Frequently Asked Questions

Yes, you can charge an EV with solar. It is the cheapest fuel you will ever put in a car.

There are 2 setups worth knowing about. The first is daytime charging directly from your panels. When your car is at home during the day and your solar is producing surplus power, that power flows into the car instead of exporting to the grid at the feed-in tariff. This works well for anyone who works from home or leaves the car in the driveway during the day.

The second is battery-linked charging. Your solar fills a home battery during the day, then you charge the car overnight from the stored solar power. This suits anyone who commutes and cannot charge during solar hours.

The best setup combines all three: solar, battery and a smart EV charger, designed together from day one. A smart charger like Zappi or Wallbox reads what your solar is doing in real time and only draws surplus power, so you never accidentally pull expensive grid electricity into the car.

There are 3 ways to charge an electric car at home in Australia. Standard power point, dedicated 7kW wall charger, or 22kW three-phase fast charger. The right choice depends on how much you drive and what electrical setup your home has.

A standard power point delivers around 2 kilowatts. That is enough to add roughly 10 to 15 kilometres of range per hour. Fine as an occasional backup or for a plug-in hybrid though slow for a daily-driven EV.

A 7kW single-phase wall charger is the standard home setup. It fully charges most EVs overnight and works with the same power supply almost every Brisbane home already has. This is where most people land.

A 22kW three-phase charger is the fastest home option. It needs three-phase power and a car that can accept a 22kW AC charge, which most current EVs cannot. Worth considering if you already have three-phase power at home or drive one of the few cars that supports it.

Volteam installs all three setups across Brisbane. Get a quote at volteam.com.au to work out which fits your home and driving pattern.

Charging time for an electric car in Australia depends on the charger and the car. A typical mid-size EV takes anywhere from 30 minutes to 36 hours for a full charge, depending on where you plug in.

A standard power point takes 24 to 36 hours for a full charge. Adds around 10 to 15 kilometres per hour. Fine as a top-up or backup.

A 7kW home wall charger takes 6 to 10 hours for a full charge on most EVs. This is the standard home setup and covers overnight charging comfortably.

A 22kW three-phase home charger takes 3 to 5 hours. Only useful if you have three-phase power and a car that accepts 22kW AC. Most EVs cap at 7 or 11kW AC.

A public DC fast charger takes 30 to 60 minutes for an 80% charge. Handy for road trips though expensive per kWh compared to home charging.

For a Brisbane home with regular driving, a 7kW overnight setup covers everything without needing a public charger. Volteam installs 7kW and 22kW EV chargers across Brisbane.

For most Brisbane homes, a 7kW EV charger is the right choice. A 22kW charger only makes sense if you have three-phase power and a car that can actually accept 22kW AC, which most current EVs cannot.

A 7kW single-phase charger delivers a full overnight charge on almost every EV sold in Australia. It works with the standard single-phase power supply in most homes. Install is simpler and cheaper. Cars that only support 7 or 11kW AC charging get the same benefit either way.

A 22kW three-phase charger needs three-phase power at your switchboard. If your home has single-phase power, adding a three-phase upgrade costs several thousand dollars, which wipes out the reason to install a faster charger. Then there is the car. Most EVs on the road today cap AC charging at 7 or 11kW. A 22kW charger on a 7kW car still charges at 7kW.

If you have three-phase power at home and drive a car that supports 22kW (some Renault, Audi and Porsche models), the extra speed is a genuine benefit. For everyone else, 7kW is the sensible choice.

Home solar batteries in Australia cost around $800 to $1,200 per kilowatt-hour installed before the federal rebate. That figure falls as batteries get bigger, because the fixed install cost spreads across more capacity.

A 10 kilowatt-hour battery at $10,000 installed works out to $1,000 per kWh. A 20 kilowatt-hour battery at $16,000 works out to $800 per kWh. Larger systems get better value per unit of storage.

After the federal rebate, the effective per-kWh price drops. The rebate is calculated at around $271 per usable kWh of the first 14 kWh at the current 2026 rate. A $1,000 per kWh install becomes closer to $730 per kWh after rebate for the first 14 kWh of capacity.

This is why size matches usage, not just budget. Undersizing means paying a higher per-kWh price for a battery that fills up too early in the day. Oversizing means paying for capacity you never draw down.

For a Brisbane household using 15 to 20 kilowatt-hours a day with the majority of that after dark, a 10 to 13 kilowatt-hour battery hits the sweet spot on both cost per kWh and daily fill rate.

Payback on a solar battery in Brisbane sits at 10 to 16 years for a typical install in 2026. For a well-sized battery in a home with high evening use, favourable solar production and a low feed-in tariff, the timeline can shorten to 8 to 12 years.

The payback maths comes down to daily bill savings versus install cost. A 10 kilowatt-hour battery delivering 8 to 9 kilowatt-hours of usable daily storage in a Brisbane home typically saves $500 to $800 a year in electricity costs. At a post-rebate install cost of $5,300 to $9,300, that returns the investment in 8 to 16 years depending on the numbers.

Payback shortens when a few things line up. High after-dark electricity use pulls the timeline in, because a battery replaces expensive grid power every night. Low feed-in tariffs help too, because storing your own solar makes more sense than selling it cheap.

Payback stretches when the opposite happens. Households with low evening use, high feed-in tariffs, or oversized batteries all see slower returns.

Rising grid electricity prices shorten payback across the market. Every retail price rise makes a battery a better investment because you avoid more expensive grid power each night.

Volteam runs the actual numbers on your home before quoting a battery. Get a proper payback estimate at volteam.com.au.

Charging an electric car at home in Australia costs around $5.80 per 100 kilometres on standard grid electricity. Most popular EVs sold here use 15 to 20 kilowatt-hours per 100km. At the Queensland residential rate of around 32 cents per kWh, that works out to roughly $4.80 to $6.40 per 100km depending on the car.

Compare that to petrol. A typical petrol SUV at 7.5 litres per 100km costs around $14 per 100km at $1.90 per litre. An EV on grid power runs at about 40 cents in the dollar compared to petrol.

Charge from your own solar during the day and the cost drops to almost nothing. Excess solar power that would otherwise export to the grid at a feed-in tariff of 10 to 12 cents per kWh goes into the car instead. For most Brisbane homes with a decent solar system, this is the cheapest fuel you can put in a car.

Setup matters. A dedicated 7kW wall charger installed in the garage or carport gives a full overnight charge and lets you schedule charging when solar is running. A standard power point works in a pinch, though it takes 24 hours or more for a full charge.

The federal solar and battery rebates are available to residential and eligible small business properties in Australia that meet a few conditions. Your installer handles the paperwork so you rarely deal with it directly.

The core eligibility requirements are set by the Renewable Energy Electricity Regulations 2001 and administered by the Clean Energy Regulator. Your system needs to meet 4 conditions.

First, the installer must be accredited by Solar Accreditation Australia (SAA). For a battery install, the installer needs the appropriate battery endorsement. Only accredited installers can create the Small-scale Technology Certificates that generate the rebate.

Second, the products used (solar panels, inverters, batteries) must be approved by the Clean Energy Council. Unapproved products do not qualify.

Third, the install location must be a residential premises or an eligible business. Most Australian homes qualify.

Fourth, the system size must fall within eligible ranges. For solar, that is up to 100 kilowatts. For batteries under the Cheaper Home Batteries Program, it is 5 to 100 kilowatt-hours of nominal capacity. Batteries must also comply with AS/NZS 5139:2019 and be capable of participating in a virtual power plant if grid-connected.

Volteam handles the paperwork and confirms eligibility as part of every quote. Get yours at volteam.com.au.

The federal Cheaper Home Batteries Program discount is calculated using Small-scale Technology Certificates (STCs) based on the battery’s usable kilowatt-hour capacity. For the May to December 2026 period, the discount works out to around $271 per usable kWh for the first 14 kWh, then $162 per kWh for capacity from 14 to 28 kWh.

The mechanism works like this. The battery earns a set number of STCs based on its usable capacity. Your installer applies for the STCs and sells them into the market at around $39 to $40 each. That value comes off your quoted price directly, so you see the discounted number rather than paying full price and claiming back.

Worked examples for May to December 2026:

A 5 kWh battery earns 34 STCs, worth around $1,355 off the price.

A 10 kWh battery earns 68 STCs, worth around $2,710 off the price.

A 13 kWh battery earns 88.4 STCs, worth around $3,523 off the price.

A 20 kWh battery earns 119 STCs, worth around $4,766 off the price.

Above 28 kWh, the discount tapers further to $61 per kWh, capped at 50 kWh of usable capacity.

The rebate declines every 6 months until 2030. From January 2027 the per-kWh rate drops to around $228 for the first 14 kWh. Volteam builds the current rebate into every battery quote. Get yours at volteam.com.au.

The federal Cheaper Home Batteries Program runs until the end of 2030. The rebate value declines every 6 months over that period, so the earlier you install, the higher the discount.

The step-down uses the Small-scale Technology Certificate (STC) factor. For the May to December 2026 period, the factor is 6.8 STCs per usable kWh for the first 14 kWh. Here is the full schedule:

• January to June 2027: 5.7
• July to December 2027: 5.2
• January to June 2028: 4.6
• July to December 2028: 4.1
• January to June 2029: 3.6
• July to December 2029: 3.1
• January to June 2030: 2.6
• July to December 2030: 2.1

The same battery installed today attracts a bigger rebate than one installed in a year, and a much bigger rebate than one installed in 2029. Battery prices are also expected to decline over the scheme’s life, which partially offsets the smaller rebate.

The federal scheme is separate from state schemes. Queensland has a history of state battery incentives that come and go independently. Check both when researching what applies to your install.

Volteam confirms the current rebate on every quote. Get yours at volteam.com.au.

The federal solar rebate is a discount at the point of install, not cash in hand. Your installer applies it directly to your quoted price, so what you see on paper is already the after-rebate figure.

The mechanism runs through Small-scale Technology Certificates (STCs). Every eligible solar system generates a set number of STCs based on the system’s kilowatt capacity, the location’s solar generation zone and the remaining deeming period. Brisbane sits in Zone 3, one of the higher-value zones.

For solar installed in 2026, the deeming period is 5 years. That drops by one year each January until the scheme ends in 2030. So a solar system installed today generates more STCs than the same system installed next year.

Your installer applies for the STCs on your behalf, sells them into the market at around $39 to $40 each, and passes the value through as a discount on your invoice. You never handle the STCs directly or wait for a cash payment.

The battery rebate under the Cheaper Home Batteries Program uses the same STC mechanism with a different formula. The battery earns STCs based on its usable kWh capacity multiplied by the current STC factor (6.8 per kWh for May to December 2026 for the first 14 kWh).

Volteam handles all rebate paperwork as part of every install. Get a quote with the current rebate built in at volteam.com.au.

The Cheaper Home Batteries Program is a federal Australian government scheme that reduces the upfront cost of installing a home battery by around 30%. It runs until the end of 2030 and applies to residential and eligible business installs across Australia.

The program works as an expansion of the existing Small-scale Renewable Energy Scheme (SRES) that has driven Australia’s rooftop solar uptake for over a decade. Batteries between 5 and 100 kilowatt-hours of nominal capacity now generate Small-scale Technology Certificates (STCs) just like solar systems have for years.

The Clean Energy Regulator administers the program. Your installer handles the paperwork, applies for the STCs on your behalf, and passes the discount through to your quoted price. You never see the STCs directly.

The discount is calculated on usable capacity, capped at 50 kWh. The first 14 kWh earns the full rate. Capacity from 14 to 28 kWh earns 60% of the rate. Capacity from 28 to 50 kWh earns 15% of the rate. This taper keeps the scheme sustainable while still supporting larger battery installs.

Eligibility requires an installer accredited by Solar Accreditation Australia with a battery endorsement, Clean Energy Council approved battery products, and the install must meet AS/NZS 5139:2019 safety standards. The battery must also be virtual power plant capable if grid-connected.

The rebate value declines every 6 months until 2030. Earlier installs attract a higher rebate. Volteam handles all Cheaper Home Batteries Program paperwork and applies the discount to every quote. Get yours at volteam.com.au.

Adding a battery to an existing solar system qualifies for the federal battery rebate under the Cheaper Home Batteries Program. The battery rebate is separate from the original solar rebate, and applies to the battery install regardless of when the solar was installed.

The original solar rebate was a one-time discount at the time your solar system was first installed. You have already received that benefit and cannot claim it again on the same system.

The battery rebate is a distinct scheme. It applies to the new battery install and generates its own set of Small-scale Technology Certificates based on the battery’s usable capacity. Your installer handles the paperwork and passes the discount through to your quoted price.

The installer needs to confirm your existing solar system is compatible with the new battery. Most modern solar setups work with an AC-coupled battery that connects to the existing inverter. Older systems may need an inverter upgrade or a hybrid inverter to work with a DC-coupled battery.

Only one battery per premises is eligible for the rebate under current rules. If you add a second battery in future, that install may not qualify.

Volteam runs a compatibility check on your existing solar before quoting a battery. That includes checking your inverter model, switchboard capacity and whether you have room for backup wiring if wanted. Get a quote at volteam.com.au.

The solar feed-in tariff is what your electricity retailer pays you for excess solar power you send back to the grid. When your panels make more electricity than your home is using, the surplus flows out to the network and your retailer credits your bill at a set rate per kilowatt-hour.

The tariff rate is set by your retailer, not the government. Rates vary widely between retailers and change over time. In South East Queensland (Energex area), competitive retailer feed-in offers sit around 10 to 12 cents per kilowatt-hour. In regional Queensland (Ergon area), the Queensland Competition Authority sets the regulated tariff, which is around 6 cents per kWh from July 2026.

Compare that to what you pay to buy electricity from the grid: around 32 cents per kWh in Queensland. The gap between what you get paid for exports (10 to 12 cents in SEQ) and what you pay for imports (32 cents) is around 20 cents per kWh. That gap is why storage makes sense. A battery lets you use your own solar power at night instead of selling it cheap and buying it back expensive.

Feed-in tariffs have declined significantly over the last decade. Older solar owners on legacy premium tariffs (up to 44 cents per kWh) keep those rates until their scheme ends. New solar installs get the standard retailer rate.

Some retailers offer higher feed-in tariffs alongside higher usage charges. Compare the whole plan, not just the tariff, when shopping for a retailer.

Volteam sizes solar and battery together to make the most of what your feed-in tariff is worth. Get a quote at volteam.com.au.

Solar batteries only work in a blackout if they are set up with backup capability. A standard grid-tied battery shuts down when the grid goes down, for safety reasons. Adding backup functionality is a separate configuration at install.

The reason standard batteries shut down is called anti-islanding. When the grid goes down, network technicians work on the lines. If solar panels or batteries kept feeding power back into the network, that would put those workers at risk. The inverter detects loss of grid voltage, abnormal frequency or other disturbances, and disconnects from the network within the required protection time.

Backup-capable batteries get around this with an automatic transfer switch or backup gateway that isolates your home from the grid during an outage. The battery then powers your home directly through a set of essential circuits, creating a controlled local voltage and frequency. When the grid returns, the transfer switch reconnects and normal operation resumes.

Backup circuits are usually a subset of the home rather than the whole house. Fridge, lights, internet, phone chargers and a few power points typically make the essentials list. Full-home backup needs more battery capacity and heavier transfer switching, which costs more.

Backup runtime depends on the battery capacity and the load. A 10 kilowatt-hour battery running essential circuits at 500 watts lasts around 20 hours. Same battery running a 2kW load lasts 5 hours.

Volteam installs battery systems with backup wiring on request. Specify backup at quote stage so it can be designed in. Get a quote at volteam.com.au.

Modern home solar batteries are safe when installed by an accredited installer using approved products. The Australian safety framework is one of the strongest in the world, backed by Clean Energy Council product approval, Solar Accreditation Australia installer certification, and state electrical safety regulators.

The battery chemistry matters. Most quality home batteries now use lithium iron phosphate (LFP) chemistry, which is thermally stable, does not release oxygen during a fault, and is very difficult to set on fire. That is different from older nickel manganese cobalt (NMC) chemistry used in some earlier generations, which had higher energy density but greater thermal risks. GoodWe, Sungrow, Tesla Powerwall 3 and Sigenergy all use LFP cells.

Install standards cover ventilation, mounting, cable rating, safety switches and isolation points. AS/NZS 5139:2019 is the Australian standard for battery installation and covers battery-system location, separation from habitable areas, physical protection, wiring and isolation, enclosures, ventilation, and fire safety considerations. Your accredited installer designs the location to meet this standard.

A properly installed battery has automatic fault detection, cell temperature monitoring, and shuts itself down if anything falls outside safe operating limits.

Cheap grey-market batteries without Clean Energy Council approval or Australian support pose real safety risks. Stick with tier 1 brands installed by a licensed installer.

Volteam installs Clean Energy Council approved batteries to AS/NZS 5139 standards. Get a quote at volteam.com.au.

Solar panels only charge a battery during a blackout if the system has a backup-capable hybrid inverter. A standard grid-tied solar system shuts down when the grid goes down, for safety, and stops generating power.

The reason is anti-islanding. Standard grid-tied inverters detect a grid outage (loss of grid voltage, abnormal frequency or rate-of-change disturbances) and immediately disconnect from the network. That safety cut-out also stops the battery from charging during the outage.

A backup-capable setup uses a hybrid inverter that can operate in island mode. When the grid drops out, the hybrid inverter isolates the home from the grid using a transfer switch, then creates its own controlled local voltage and frequency. Solar panels keep generating and charging the battery independently. Essential circuits keep running throughout.

This needs to be specified at install. Retrofitting backup capability to a standard grid-tied system usually means replacing the inverter, so it is much cheaper to plan for backup from the start.

Not every home needs backup. If blackouts are rare in your area and you can manage without power for a few hours, a standard grid-tied setup saves money on the install.

Volteam installs backup-capable hybrid systems on request. Get a quote with backup wiring included at volteam.com.au.

A retrofit solar battery install takes 1 day on site for most homes. Installing a new solar and battery bundle together takes 1 to 2 days depending on system size and roof complexity.

The retrofit process starts with the installer arriving in the morning. First, they isolate power to the switchboard and any existing solar inverter. Then the battery mount goes on the wall, the battery is fixed in place, and the cabling runs to the switchboard.

Next comes the switchboard work. This is often where retrofit installs get more time. Older switchboards may need an upgrade to accommodate the battery isolation switch and any backup circuits. Commissioning follows, where the battery is tested, connected to Wi-Fi, and the monitoring app is set up.

For a full solar plus battery bundle from scratch, day 1 usually covers the roof work (panels and rails) and switchboard prep. Day 2 covers the battery install, inverter setup and commissioning.

Paperwork happens before and after the on-site work. Energex approval for grid connection is submitted before install starts. The meter alteration paperwork for solar export goes in after install is complete and the final invoice is paid.

Yes, most modern solar batteries are rated for outdoor install. GoodWe, Tesla, Sungrow and Sigenergy all offer outdoor-rated units. Check the IP rating on the specification sheet to confirm.

IP65 and IP66 are the typical ratings for outdoor solar batteries. GoodWe Lynx systems are IP65, ESA systems are IP66. That means dust-tight and protected against water jets, which covers Brisbane’s weather. IP rating alone does not certify fire safety or long-term UV durability, so location still matters.

Direct sun and heat shorten battery life. Lithium chemistry degrades faster at high temperatures. In Brisbane, avoid west-facing walls that cop the full afternoon heat. A shaded east or south wall, or a covered area under a carport or eaves, works well. GoodWe’s warranty conditions specifically require installation away from direct sunlight.

Ventilation matters. Batteries release a small amount of heat during charging and discharging. A wall install with 100 to 200 millimetres of clear space around the unit keeps operating temperatures in the ideal range.

Coastal locations need salt-corrosion consideration. Standard outdoor-rated batteries near the ocean can have shorter lifespans without additional protection. Volteam factors in salt exposure when picking install locations for Gold Coast and Sunshine Coast homes.

Some installs go in the garage instead, which gives natural shade and better temperature control year round. Others sit outside on a purpose-built stand next to the meter box. Volteam picks the right location based on your home layout and battery model. Get a quote at volteam.com.au.

A home EV charger install in Australia costs between $1,000 and $2,500 for a standard 7kW single-phase job including the charger. A 22kW three-phase install runs from $1,500 to $4,000. Difficult installs with long cable runs, trenching or switchboard upgrades can reach $3,000 to $6,000 or more.

Three things drive the price. First is the charger type. A 7kW single-phase wall charger costs less than a 22kW three-phase fast charger. Second is the distance from your meter box to where the car parks. Long cable runs or trenching add labour cost. Third is your home electrical setup. Three-phase homes have more flexibility with charger options and single-phase homes can only run 7kW without a supply upgrade.

Use a licensed EV specialist rather than a general electrician. EV chargers involve load management, energy monitoring and safety systems that a regular sparky may not be trained for. A specialist install also protects the manufacturer warranty on premium units like Zappi, Wallbox and Tesla Wall Connector.

Yes, you can add a battery to an existing solar system. Most modern solar setups are compatible with a retrofit battery. The 2 options are AC-coupled and DC-coupled, and the right choice depends on your existing inverter.

AC-coupled batteries work with any existing solar inverter. The battery has its own inverter built in, so it operates alongside your solar without needing any changes to what you already have. Slightly less efficient than a DC-coupled setup due to extra energy conversions, though far simpler and cheaper to install. This is usually the preferred retrofit approach when the existing inverter is relatively new and working properly.

DC-coupled batteries share an inverter with the solar. That means better efficiency, since power only converts once between DC and AC. The catch is that DC-coupled setups need a hybrid inverter, so if your existing solar has a standard grid-tied inverter, you may need to replace it as part of the battery install. Inverter replacement typically adds $2,000 to $3,500 to the retrofit cost.

For most retrofit installs where the existing inverter is working well, AC-coupled is the sensible choice. DC-coupled makes more sense when the existing inverter is old, needs replacement anyway, or when installing solar and battery together from scratch.

The federal battery rebate applies to the battery install regardless of when the solar was installed, and regardless of AC or DC coupling.

Volteam runs a compatibility check on your existing solar and inverter before quoting a battery. Get a quote at volteam.com.au.

Buying solar and battery together typically saves $1,500 to $3,500 compared to installing the same battery later. That works out to a 5 to 15% saving on the overall bundled install cost. Adding a battery later to existing solar still makes sense, though the retrofit costs more than doing both at once.

Together saves money in 3 places. One install visit rather than 2. One Energex application rather than 2. One switchboard upgrade rather than 2. Those savings add up.

A system designed with a battery from day one uses the right hybrid inverter for the whole setup. That means better efficiency, cleaner integration through a single app, and no wasted inverter swap later. Adding a battery to older solar with a standard grid-tied inverter often means replacing the inverter, which adds $2,000 to $3,500 to the retrofit cost.

AC-coupled retrofits eliminate most of the penalty. If your existing inverter is working well and battery-compatible on the AC side, you keep the inverter and just add the battery with its own inverter built in. The saving from bundling in that case is much smaller.

Sizing is easier when done together. Solar output and battery capacity should match your household load, and designing both at once means the right ratio between generation and storage. Retrofit installs sometimes end up with battery capacity that does not match the existing solar output.

If you already have solar and it is working well, adding a battery later is still worthwhile. The battery rebate applies regardless of when the solar was installed. Volteam handles both bundled installs and retrofits. Get a quote at volteam.com.au.

Running a whole house on battery power is possible with the right sizing and backup wiring. Most Brisbane homes go with essential circuits only, which is more economical and covers the important loads.

Whole-home backup needs a large battery. A typical home draws 5 to 10 kilowatts during peak use (aircon, oven, hot water, appliances all running). To run everything for a full evening or an overnight blackout, you need 20 kilowatt-hours or more of storage plus a battery inverter rated to handle the peak load.

The install cost sits at $18,000 to $25,000 before rebate for a full-home backup setup. Add a whole-home transfer switch and the switchboard work to isolate the home from the grid during outages, and the numbers climb further.

Essential circuits backup is the more common approach. A 10 to 13 kilowatt-hour battery powers fridge, lights, internet, hot water, phone chargers and a few power points for 12 to 24 hours during a blackout. Install cost sits at $8,000 to $15,000 before rebate.

Essential circuits also work fine for normal daily use. During normal operation, the whole home runs off solar during the day and battery at night, drawing from the grid only when the battery runs low.

Volteam designs battery systems to match household priorities. Get a quote for essential or whole-home backup at volteam.com.au.

Home solar batteries in Australia cost between $8,000 and $19,000 fully installed depending on size. A common 10 kilowatt-hour install lands at $8,000 to $12,000 before rebate. A larger 20 kilowatt-hour system runs $14,000 to $19,000 before rebate.

Size is the biggest driver. A 10 kilowatt-hour battery suits most 3 to 4 person Brisbane homes with moderate evening usage. A 13 to 16 kilowatt-hour system fits bigger households with aircon running overnight or homes charging an EV at night. A 20 kilowatt-hour or bigger system covers full-home backup requirements.

Brand matters too. Tier 1 brands like GoodWe, Sungrow and Tesla carry a premium over budget imports, backed by proper warranties and local support. Volteam recommends GoodWe as the preferred battery for most Brisbane installs, with strong Australian support and cyclone-rated options for northern Queensland.

Install complexity is the third piece. Retrofit installs on homes with existing solar are simpler and cheaper than a full solar plus battery bundle from scratch. Older switchboards, upstairs meter boxes or three-phase homes add cost.

The federal Cheaper Home Batteries Program takes around $2,700 off a 10 kilowatt-hour install and around $4,800 off a 20 kilowatt-hour install for the May to December 2026 period. After rebate, most Brisbane homeowners pay $5,300 to $9,300 out of pocket for a 10 kilowatt-hour install.

Volteam installs GoodWe, Tesla, Sungrow and other tier 1 batteries across Brisbane, the Gold Coast and Sunshine Coast. Get a real number for your home at volteam.com.au.

First a quick clarification. When people search 10kW battery they usually mean 10kWh, which is kilowatt-hours of storage, not kilowatts of output. The 2 numbers matter for different reasons and are easy to confuse.

A 10 kilowatt-hour (10kWh) battery costs $8,000 to $12,000 fully installed in Australia before rebate. It stores enough energy to run an average Brisbane household through the evening and overnight, then refills the next day from solar.

After the federal Cheaper Home Batteries Program discount of around $2,700 for a 10 kWh battery in the current 2026 period, expect to pay $5,300 to $9,300 out of pocket for a quality install. Your installer applies the rebate at the quoting stage so you see the discounted price directly.

If you actually meant a battery with 10 kilowatts of power output, that describes a battery rated to deliver 10kW instantaneously (roughly enough to run a whole home under load). Those units are typically 13 to 20 kilowatt-hours of storage and cost $10,000 to $19,000 installed.

For a typical Brisbane household of 3 or 4 people, a 10kWh storage battery hits the right size for evening use. Volteam installs across Brisbane. Get a quote at volteam.com.au.

The best solar battery in Australia is the one matched to your home. 4 things matter more than picking the loudest brand: usable capacity, warranty terms, blackout capability, and installer support.

Usable capacity is not the same as advertised capacity. A battery sold as 10 kilowatt-hours often has 9 to 9.5 kilowatt-hours of usable storage after the manufacturer sets aside a buffer to protect battery life. Check the specification sheet for usable capacity.

Warranty terms vary widely. A 10 year warranty at 70% capacity retention is stronger than a 10 year warranty at 50% retention. Tesla Powerwall 3 uses an unlimited cycle warranty. GoodWe, Sungrow and Sigenergy typically warrant 70% capacity retention over 10 years with cycle or throughput conditions.

Blackout capability is a separate feature. Grid-tied batteries shut down in a blackout for safety unless they are set up for backup. Confirm which circuits run on backup and how much of the battery capacity is reserved for outages.

Installer support matters more than brand marketing. A tier 1 brand with strong Australian support (GoodWe, Sungrow, Tesla, Sigenergy) beats a cheap import that no local installer can service in 5 years.

Volteam installs GoodWe as the preferred battery for Brisbane homes, with strong Australian support and cyclone-rated options for northern Queensland. We also install Tesla, Sungrow and other tier 1 batteries where they suit the home. Get a quote at volteam.com.au.

GoodWe is a tier 1 global solar and battery manufacturer with a strong presence in the Australian market. The GoodWe Lynx and ESA battery ranges are Volteam’s preferred batteries for most Brisbane home installs.

The Lynx and ESA ranges cover 5 to 20+ kilowatt-hours of usable capacity, sized modularly. A single battery unit or a stack of units to suit larger homes. All units share the same inverter family, so scaling up later is straightforward.

Cyclone-rated options are available for northern Queensland installs. That matters for homes in cyclone-prone areas where standard batteries would not meet install standards.

The 10 year warranty covers 70% capacity retention, meaning the battery is guaranteed to hold at least 70% of its original storage capacity after a decade of use. The ESA range uses a lifetime energy throughput limit alongside the capacity guarantee.

Hybrid inverter integration is a key benefit. GoodWe batteries pair directly with GoodWe solar inverters, so the whole system talks to itself through a single app. Cleaner than stitching together components from different brands.

A GoodWe battery in Australia costs between $7,000 and $11,000 fully installed for a 10 kilowatt-hour system before the federal rebate. GoodWe sits at the value to mid-market tier, priced above budget imports and below premium brands like Tesla Powerwall.

The GoodWe Lynx and ESA ranges start around $7,000 to $9,000 installed for a smaller 5 to 8 kilowatt-hour battery, which suits smaller Brisbane homes or homes with light evening use.

The most common install is a 10 kilowatt-hour GoodWe setup at $7,000 to $11,000 before rebate. That covers most 3 to 4 person Brisbane households comfortably.

Larger 13 to 20 kilowatt-hour installs sit at $10,000 to $16,000, often with backup wiring for essential circuits during blackouts. Good fit for bigger households, homes with EVs charging overnight, or anyone wanting full-home backup.

The federal Cheaper Home Batteries Program applies around $2,700 off a 10 kilowatt-hour install in the current 2026 period. After rebate, expect to pay $4,300 to $8,300 out of pocket for a 10 kilowatt-hour GoodWe battery install in Brisbane.

Honest answer, it depends. In Brisbane in 2026, a correctly sized solar battery typically has a simple payback of 10 to 16 years. That is longer than a lot of marketing suggests, and worth understanding before committing.

The first factor is after-dark power use. The more electricity you consume after sunset, when solar has stopped generating, the more a battery earns. Most Brisbane households use 60 to 70% of their daily power after dark, which is exactly what a battery replaces.

The second factor is whether you already have solar. Adding a battery to existing solar is cheaper and faster to pay back than installing both from scratch. Without solar, the payback stretches significantly because you have to generate the power in the first place before you can store it.

The third factor is the gap between grid rates and feed-in tariffs. In South East Queensland, grid power costs around 32 cents per kWh, while retailer feed-in tariffs sit at 10 to 12 cents per kWh. That 20+ cent gap is what a battery captures every night. A wider gap means faster payback.

For a well-sized battery in a home with high evening use, favourable solar production and a low feed-in tariff, payback can come in at 8 to 12 years. A lightly used or oversized battery can push beyond 15 years. The federal rebate improves the timeline by shortening it 2 to 3 years compared to pre-rebate maths.

Batteries also add benefits the payback calculation ignores: blackout backup, protection against rising grid rates, and independence from retailer price rises. Volteam sizes batteries based on actual household usage, not sales targets. Get a real quote at volteam.com.au.

Match battery size to what you use after dark. Not to what you use in total, and not to how much solar you generate. Start with your electricity bill.

Most Brisbane households use 15 to 20 kilowatt-hours a day. Of that, around 60 to 70% is used after sunset when solar has stopped generating. For a typical home, that means 9 to 14 kilowatt-hours of after-dark consumption. That is your battery target.

A 10 kilowatt-hour battery suits smaller Brisbane homes with lighter evening loads. A 13 to 16 kilowatt-hour system fits larger households, families running aircon overnight, or homes with an EV charged at night.

Oversizing wastes money. A battery you cannot fill during solar hours or drain during the evening is capacity you paid for and never use. It also stretches your payback timeline.

Undersizing is a daily frustration. A battery that empties by 9pm means the last few hours before bed pull from the grid at the highest rates of the day.

The right sizing looks at your electricity bill, your evening usage pattern, whether you have an EV or plan to get one, and your daily solar generation. Interval data from a smart meter shows exactly when you use power. Volteam runs this sizing analysis as part of every battery quote. Get yours at volteam.com.au.

A 10 kilowatt-hour battery is enough for smaller Brisbane households with modest evening electricity use. For larger homes running aircon overnight, EV charging at night, or high evening loads generally, a 13 to 16 kWh system is a better fit.

The rule of thumb is your after-dark consumption. Most Brisbane homes use 60 to 70% of their daily electricity after sunset. For a household using 15 kWh a day total, that is 9 to 10 kWh of evening and overnight usage. A 10 kWh battery covers that comfortably.

For a household using 20 kWh a day total, evening use runs to 12 to 14 kWh. A 10 kWh battery empties before dawn and the last few hours before sunrise pull from the grid at peak rates. That is a real cost across a year.

Heavy evening use adds up quickly. Reverse-cycle aircon at 2kW running from 6pm to 10pm uses around 8 kWh. An EV charging at 7kW overnight uses 30 to 50 kWh. Neither fits inside a 10 kWh battery.

The right answer depends on your bill and your habits. Volteam sizes every battery based on real household usage rather than a default number. Get a proper sizing analysis at volteam.com.au.

A 6.6kW solar system typically pairs with a 10 to 13 kilowatt-hour battery in Brisbane. That combination captures most of your daily solar surplus without oversizing beyond what the system can fill.

A 6.6kW solar system generates around 25 to 29 kilowatt-hours a day averaged across the year in Brisbane’s climate. Your home uses 5 to 10 kWh during solar hours (fridges, standby loads, some daytime cooking). That leaves 15 to 24 kWh of surplus available for storage or export each day.

A 10 kWh battery captures most evening use for a smaller home and leaves plenty of surplus to export. A 13 kWh battery covers larger evening loads and reduces grid draw before sunrise. Anything you cannot fit in the battery exports to the grid at 10 to 12 cents per kWh in South East Queensland.

Going bigger than 13 kWh on a 6.6kW solar system usually leaves capacity underused. The battery can charge fully but only if you have consistently sunny days. Cloudy weeks leave a bigger battery partially filled.

The right pair depends on your evening use, not just the solar size. Volteam sizes solar and battery together so both work at their best. Get a quote at volteam.com.au.

Quality solar batteries in Australia come with a 10 year manufacturer warranty and typically deliver 12 to 15 years of real service. Two things matter here: the warranty terms and the underlying battery chemistry.

The 10 year warranty covers a minimum performance level. Most tier 1 brands (GoodWe, Sungrow, Tesla, Sigenergy) guarantee 70% capacity retention at the end of the warranty period. That means a 10 kilowatt-hour battery at year 10 still stores at least 7 kilowatt-hours of usable energy.

Real world lifespan usually exceeds the warranty. Lithium iron phosphate (LFP) batteries, which most quality home batteries now use, are more thermally stable than earlier chemistries and degrade more slowly. Expect 12 to 15 years of practical service for a well-installed LFP battery, sometimes longer.

Warranty structures vary between brands. GoodWe warrants the ESA range at 70% capacity retention. Tesla Powerwall 3 uses an unlimited cycle warranty. Sungrow and Sigenergy typically publish around 6,000 cycles or an energy throughput limit, whichever comes first.

Read the warranty carefully. A 10 year warranty at 70% capacity retention is stronger than one at 50%. Check whether the warranty covers labour, what the operating temperature conditions are, and whether the warranty tracks calendar years, cycle count or energy throughput.

Volteam installs tier 1 batteries with strong warranties. Get a quote at volteam.com.au.

Home solar batteries need very little hands-on maintenance. Modern lithium iron phosphate batteries are sealed units with no fluids to top up or components to service. What they do need is a light annual check and firmware updates, which happen automatically.

Firmware updates come through the manufacturer app over your home internet. GoodWe, Sungrow and Tesla all push updates without needing anyone on site. Keeping the battery connected to Wi-Fi is enough.

An annual visual check picks up anything unusual. A good installer looks at cable connections, checks the battery is sitting cleanly on its mount, wipes dust off vents, and confirms the monitoring app is reporting normal cycles. Takes 20 minutes.

For outdoor installs in dusty environments, clean the intake vents twice a year. A soft brush handles it. Indoor units sitting in a garage rarely need cleaning.

The manufacturer app also gives you a running health check. It shows charge cycles, capacity, and flags any faults early. Most homeowners check the app once a week for the first month then forget about it.

Volteam includes an annual check-in as part of aftercare on every battery install. Get a quote at volteam.com.au.

A home solar battery stores surplus solar power during the day and releases it after dark. The whole system works in 3 stages.

Stage 1 is generation. Your solar panels produce electricity whenever the sun is shining. On a sunny Brisbane day, a typical 6.6kW system generates 25 to 29 kilowatt-hours. Anything your home uses right now (fridge, aircon, appliances) draws straight from the panels.

Stage 2 is storage. Anything you generate but do not use right away flows into the battery instead of exporting to the grid. The battery charges through the day until it hits full capacity, then anything above that exports to the grid at the feed-in tariff rate of 10 to 12 cents per kWh in South East Queensland.

Stage 3 is use. When the sun goes down and your panels stop generating, your home draws power from the battery first. Only once the battery is empty do you pull from the grid at around 32 cents per kWh. For most Brisbane homes with a properly sized battery, the grid kicks in only during the last hours before sunrise.

Backup capability is a fourth feature on some batteries. If configured for backup, the battery keeps essential circuits running during a blackout. Standard grid-tied batteries shut down in a blackout for safety (see the anti-islanding FAQ), so backup capability needs to be specified at install.

Once a solar battery is full, any excess solar power flows to the grid at your retailer’s feed-in tariff rate. The battery management system stops charging automatically, protecting the battery from overcharging.

This is normal and expected. A well-sized battery hits full capacity by mid to late morning on a clear day. From that point until the sun goes down, your home draws directly from the panels for immediate use, and anything above that exports to the grid.

The feed-in tariff is set by your retailer and varies. In South East Queensland, competitive feed-in offers sit around 10 to 12 cents per kilowatt-hour. Regulated regional Queensland tariffs from July 2026 are around 6 cents per kWh. Either rate is less than you pay to buy grid power (around 32 cents per kWh), which is exactly why storage makes sense in the first place.

If your battery hits full capacity every day by 10am, that is a sign it is undersized for your solar output. You are exporting a lot of power at cheap feed-in rates that could otherwise cover more of your evening use.

Proper battery sizing looks at solar generation, daytime use and evening use, and fills the battery to full most days without exporting significant surplus.

The right inverter size depends on factors such as your solar panel capacity, household electricity usage, export limits, and local installation requirements. A qualified solar installer can recommend an appropriate size for your system. 

The right inverter size depends on factors such as your solar panel capacity, household electricity usage, roof space, export limits, and local installation requirements. Here are some examples to help:

• Small residential home: A 2-3 bedroom home with moderate electricity usage could suit a 5kW solar system with a 5kW inverter.
• Larger residential home: A 4-5 bedroom home with higher electricity usage could suit a 6.6kW solar system with a 5kW inverter or a larger system with a 6kW inverter, depending on the home’s energy needs and export limits.
• Small commercial property: A small office, retail shop, or similar business with higher daytime electricity usage could suit a 10-20kW solar system with a 10-15kW inverter, depending on energy consumption, available roof space, and network requirements.

These are general examples only. A qualified solar installer can assess your electricity usage, roof space, and local requirements to recommend the right inverter size for your property.

For instance, if you have a standard detached or semi-detached house in Brisbane and want a moderate solar setup, you could opt for a 6.6kW solar system with a 5kW inverter. This takes around 15 panels, so it is great for single-home roofs and is among the more affordable options.

The cost of a solar inverter in Australia depends on its capacity, brand, features, and whether it is installed as part of a new solar system or as a replacement. Plus, the price depends on the type of inverter. Is it a microinverter (which can cost around $150 to $300), a string inverter (around $1,000 to $3,000), or a hybrid inverter (the most expensive at between $2,000 to $5,000)? Installation and system requirements can also affect the total price.

A solar inverter is a fairly small electrical appliance that converts the DC (direct current) electricity generated by your solar panels into AC (alternating current) electricity that can be used by your home and your other electrical appliances. It also helps monitor and manage your solar system. The excess energy that it generates (i.e., the energy that you don’t use) can potentially be sent to the grid for a rebate or stored in a compatible solar battery.

The best solar inverter depends on your system size, budget, battery plans, monitoring requirements, and other installation needs. Popular inverter brands in Australia include GoodWe, Sungrow, Fronius, and SolarEdge.

The best solar inverter depends on your system size, budget, battery plans, energy usage, and installation requirements. Different inverters can suit different types of homes and solar systems.

For example:

• For a household with solar panels, high energy usage, and an EV, GoodWe can be a good option, particularly if you want to combine solar, battery storage, and EV charging.
• For a large home with a larger roof and higher energy needs, Sungrow offers a range of inverters that can suit larger solar and battery systems.
• For homeowners looking for advanced monitoring and panel-level optimisation, SolarEdge can be a suitable choice, particularly where roof layout or partial shading makes optimisation important.

Other popular inverter brands in Australia include Fronius. The right choice ultimately depends on your home’s energy usage, solar system size, battery plans and site conditions. A qualified solar installer can recommend the most suitable inverter for your property.

Yes, you need a solar inverter if you want to use the electricity generated by your solar panels in your home. A solar inverter converts DC electricity generated by solar panels into AC electricity, which is what your home appliances use (like lights, appliances, air conditioning, and washing machines).

This means you can’t simply install solar panels and connect them directly to your household appliances. You need an inverter to make the electricity generated by your panels usable.

A good inverter can also help you monitor how much solar energy you’re producing and using, manage energy flows, and (depending on the model) work with a home battery or EV charger. This can help you use more of your own solar power and reduce the amount of electricity you need to buy from the grid.

So, while solar panels generate the energy, the inverter is what makes that energy practical and usable for your home. Choosing the right inverter is an important part of getting the most from your solar system.

Solar inverters commonly last around 10-15 years, although the exact lifespan depends on the inverter type, quality, installation conditions, operating environment, and maintenance. Solar panels generally last much longer, so your inverter may need to be replaced at least once during the life of your solar system.

For example, an inverter installed in a cool, well-ventilated location may experience less heat stress than one exposed to high temperatures. Regular monitoring and addressing faults early can also help maintain its performance.

Most manufacturers provide warranties covering their inverters, but the warranty period varies between brands and models. When choosing an inverter, it’s worth considering both its expected lifespan and warranty coverage, not just the upfront price.

Solar inverters generally require limited routine maintenance, but they should be monitored for error messages, unusual operation, and performance issues. Professional inspections can help identify potential problems early. Volteam provides friendly support after installation, so you can rest assured you’re getting quality maintenance for your solar inverter.

If a solar inverter stops working, your solar system may stop producing usable electricity even if the panels are still generating power. The inverter display or monitoring platform may show an error that can help identify the issue. If you’re experiencing issues with your solar inverter, please contact Volteam on 1300 865 832.

The right inverter brand depends on your solar system size, energy usage, roof configuration, battery plans, and installation requirements.

The cost of solar panels in Australia depends on the system size, panel brand, and model, installation requirements and other components included in the system. Government incentives and rebates may also affect the final cost.

The cost of solar panels in Australia depends on the system size, panel brand and model, installation requirements, inverter, and other components included in the system. Government incentives and rebates may also reduce the upfront cost.

As a broad guide, a typical residential solar system installation in Australia may cost around:

• 5kW system: approximately $5,000-$8,000 AUD
• 6.6kW system: approximately $6,000-$10,000 AUD
• 10kW system: approximately $9,000-$14,000 AUD

Larger systems, premium panels, complex roof installations, or additional equipment such as a battery can increase the total cost.

These are indicative price ranges only, and the actual cost will depend on your property, system design, equipment and available rebates. A qualified solar installer can provide an accurate quote based on your energy needs and property.

The best solar panel depends on your available space, energy needs, budget, and the type of property you are installing the system on. Different panels can make more sense in different situations.

For example:

• For a small home with limited roof space: Choose high-efficiency panels, such as REC or SunPower, so you can generate more electricity from a smaller number of panels.
• For a typical family home: Jinko Solar or Trina Solar can be a good option if you want a balance of performance, reliability and value.
• For an office or commercial building: Larger-format panels from brands such as Trina Solar or Jinko Solar can be suitable for larger systems where there is plenty of roof space and high daytime electricity usage.
• For a large ground-mounted system with plenty of land: Cost-effective, larger-format panels from brands such as Jinko Solar or Trina Solar can be a practical choice, helping keep the overall cost per watt lower for larger installations.

When choosing solar panels, consider efficiency, warranty, degradation rates, available space, and the overall cost of the system. A qualified installer can recommend the most suitable panels based on your property and energy requirements.

Solar panels use photovoltaic cells to convert sunlight into DC electricity. The electricity is then sent to an inverter, which converts it into AC electricity that can be used by your home or business.

The number of solar panels you need depends on your electricity usage, available roof space, panel wattage, and the size of the solar system you want to install. As a general guide, assuming panels of around 440W, you could expect:

• Small home with moderate electricity use: A 3.3kW system would require around 7–8 panels and may suit a smaller 1–2 bedroom home or household with lower energy usage.
• Typical family home: A 6.6kW system would require around 15 panels and is a common choice for a 3–4 bedroom home with moderate to high electricity usage.
• Large home with higher electricity use: A 10kW system would require around 22–23 panels and could suit a larger 4–5 bedroom home with higher energy consumption, including households with air conditioning or an EV.
• Small commercial property: A 20kW system would require around 45–46 panels and could suit a small office, retail property or other business with significant daytime electricity usage.

These are general examples only. The ideal number of panels will depend on your energy consumption, roof size, panel specifications, shading and local network requirements. A qualified solar installer can design a system that matches your property’s energy needs.

Absolutely! For many Australian households, solar panels can be a worthwhile investment because they allow you to generate your own electricity instead of buying as much power from the grid.

For example, when your solar panels are producing electricity during the day, you can use that energy to run air conditioning, appliances, pool pumps, hot water systems, and other household devices. This can reduce the amount of electricity you need to purchase from your energy retailer.

Solar can be particularly valuable for households that use a lot of electricity during the day. You can also use excess solar generation to charge a home battery or an EV, making better use of the energy your panels produce.

Another benefit is that solar can help reduce your exposure to changes in electricity prices. Instead of purchasing all of your electricity from the grid, you generate a portion of your own energy for many years.

The financial benefits depend on factors such as your system size, installation cost, electricity usage, solar generation, feed-in tariff and available government incentives. For many homeowners, the key is to choose a system that matches their energy usage rather than simply installing the largest system possible.

Overall, solar panels can be a good option for Australian households looking to reduce electricity bills, generate their own renewable energy and make better use of their home’s energy.

Solar panels are designed for long-term operation and typically last around 25-30 years. They can continue generating electricity beyond this point, but their energy output gradually decreases over time.

Most quality solar panels come with long-term performance warranties that guarantee a certain level of power output after 25 years. The actual lifespan can depend on the panel technology, manufacturer, installation quality and environmental conditions such as heat, humidity, and exposure to the elements.

This means a well-maintained solar system can continue helping you generate electricity and reduce your reliance on grid power for decades.

Solar panels generally require relatively little maintenance. Keeping panels reasonably clean and having the system inspected when necessary can help maintain performance. Monitoring your system can also help identify potential problems.

Solar panels continue to operate when it rains, although electricity production is generally lower because there is less sunlight. Rain can also help wash dust and light dirt from the panels, so the occasional rainfall can actually be beneficial for solar panels.

Yes. Solar panels can still generate electricity on cloudy days because they can use available daylight. However, their electricity production is usually lower than on a clear, sunny day.

Solar panels generate DC electricity, while standard household electrical systems use AC electricity. Therefore, a typical home solar system needs an inverter to convert the electricity into a usable form.

A standard grid-connected solar system will generally shut down during a grid outage for safety reasons. Solar systems designed with suitable battery backup and backup functionality may be able to provide power during an outage, depending on the system configuration.

Solar panels can be an attractive feature for some home buyers because they can help generate renewable electricity and potentially reduce electricity costs. The impact on property value varies depending on the property, system and local market.

Monocrystalline and polycrystalline panels use different manufacturing processes and have different characteristics, including efficiency and appearance. Monocrystalline panels are commonly used in modern residential installations because of their efficiency and space-saving potential.

In many cases, a battery can be added to an existing solar system, but the compatibility of your existing inverter, solar system, and battery needs to be checked before installation.

The main benefit of adding a battery is that it allows you to store excess solar energy generated during the day and use it later, such as in the evening or at night when your panels are not producing electricity. This can help you use more of your own solar power and reduce the amount of electricity you need to buy from the grid.

A battery can also be useful for households with higher evening energy usage or those looking to have greater energy independence. A qualified installer can assess your existing system and recommend a compatible battery solution.
