Brand Overview: GoodWe vs Sungrow
Sungrow is established and well-known worldwide, with a strong reputation for its cutting-edge solar technology. Meanwhile, GoodWe has quickly earned a reputation for its advanced solar products, with a focus on smart energy management.
GoodWe Solar Battery Models
For residential customers, there are four main models available. With a long lifespan, all of their batteries use lithium-iron phosphate (LFP) cell chemistry.
- Lynx Home U Series: A low-voltage battery solution that’s only compatible with GoodWe’s ES and SBP inverters. It is available in 5.4 kWh, with up to six modules that can be combined to reach a total capacity of 32.4 kWh.
- Lynx Home F Series: Compatible with GoodWe EH and ET inverters, but it can only be ground-mounted. GoodWe’s F Series is a high-voltage battery solution that offers faster charging and discharging rates across 6.6 kWh units up to 16.5 kWh. Faster rates are beneficial for high-power applications, but there’s a risk of a reduced lifespan.
- Lynx F G2 Series: Seen as an upgrade of the F Series, although both are high voltage and share the same appearance and stackability features. The difference is that the F G2 Series utilises newer battery modules individually rated at 3.2 kWh. Additionally, it includes a minimum of 2 modules (6.4 kWh), which can be stacked to a maximum of 9 modules (28.8 kWh).
- GoodWe ESA Series: An all-in-one home energy storage system with an integrated inverter, designed for fast installation and a clean setup. The ESA Series offers scalable storage, smart energy management, and reliable backup power, making it ideal for homeowners seeking simplicity, efficiency, and long-term performance.
Sungrow Solar Battery Models
Sungrow has two solar battery series to choose from when it comes to solar battery installation:
- SBR Series: The SBR Series is noteworthy for delivering up to 100% usable energy, meaning you can utilise the entire battery capacity. It supports three to eight modules per unit with a capacity range of 9-100 kWh.
- SBH Series: The SBH series is designed for small commercial solar or large residential applications since additional modules can be stacked to reach 40 kWh. Just like the SBR battery, the SBH Series also has an IP55 environmental rating.

GoodWe Pros and Cons
Here are some of the pros and cons of getting a GoodWe solar battery.
- All-Back-Contact (ABC) Cell Technology: This tech makes AIKO solar panels shine, not just aesthetically, but in the efficiency of their modules.
- High Efficiency & Energy Output: The AIKO Neostar Series, for instance, achieves a maximum efficiency of 24.3% while being suited for residential applications.
- Durable, Reliable Panels: Durability-wise, it is resistant to hail and harsh conditions with special protective casing and materials.
- Optimised for Performance: AIKO solar panels are optimised for partial shade scenarios, reducing energy loss, plus it has a low performance degradation over time.
LONGi vs AIKO: Price and Warranty
LONGi solar panels are usually more affordable than AIKO solar panels. However, AIKO is considered the more advanced and sleeker choice in terms of appearance.
For example, the approximate price of a single AIKO 470 Watt Neostar 2P solar panel is around $200-$300, while a LONGi Hi-Mo 6 430W costs around $170 per panel.
In terms of warranty, AIKO offers a stronger one with a 15-year product warranty (extendable to 25 years) and a 30-year performance warranty. LONGi, meanwhile, offers a 12-year warranty for most of its panels, plus a 30-year linear warranty.
GoodWe Pros and Cons
Here are some of the pros and cons of getting a GoodWe solar battery.
Pros
Stackable Modules: Providing greater flexibility, as owners can easily scale energy capacity by adding up to eight modules on top of each other. This is ideal for those who are looking to increase their energy storage capacity in the future.
Long Lifespan: The Lynx A and U batteries deliver long-lasting performance with a lifecycle of up to 6,000 cycles.
Lithium Iron Phosphate (LiFePO4): Its use of Lithium Iron Phosphate, currently the most popular battery chemistry, means that your energy storage system is safe and reliable. Lithium Iron Phosphate is trusted for its stable performance and high depth of discharge.
Cons
Compatibility: While there’s some benefit to built-in inverters, if you’re adding to an existing system, the battery is compatible only with a GoodWe inverter.
Cost: Slightly more expensive compared to other batteries in the same category.
Warranty: Unclear wording regarding coverage of transport and labour costs; rates and maximums are at the manufacturer’s discretion.
Sungrow Battery Pros and Cons
Here are some of the pros and cons of the Sungrow solar battery:
Pros
Modular and Stackable Design: Sungrow allows users to add capacity as their needs change.
High Round-Trip Efficiency: Sungrow’s solar batteries achieve over 95% efficiency, mitigating energy loss during use.
Ease of Installation: Placement options are more flexible, as Sungrow batteries can be mounted either on the wall or on the floor. It’s also plug-and-play, meaning no cables are required between battery modules.
Cons
DC-Connection: Not a good option if you already have solar installed without a hybrid inverter.
Warranty: Excludes labour, freight, and waste disposal associated with claims after 5 years.
New Installations: Battery additions must be manually balanced or commissioned to match, which can be a technical constraint.
Frequently Asked Questions
Which solar battery is more flexible for installation, Sungrow or GoodWe?
GoodWe batteries are floor-standing models, which can limit placement options if you’re tight on space. In comparison, Sungrow batteries offer more flexibility with wall-mounted and floor-standing options and are lightweight, allowing one person to carry out the installation on their own.
GoodWe vs Sungrow: Which Solar Battery Provides Higher Efficiency?
GoodWe batteries are high-efficiency and reliable, but Sungrow has slightly higher overall efficiency ratings. If your storage needs are smaller, GoodWe is a solid choice, but Sungrow’s smart hibernation technology optimises efficiency and reduces consumption during periods of low demand.
Is Sungrow or GoodWe Better for Safety and Reliability?
Both brands use LiFePO4 chemistry, the leading battery technology, so they’re similarly matched in terms of safety and reliability. GoodWe prioritises safety during scalability, so larger systems are stable and reliable. Sungrow uses remote diagnostics and smart hibernation to enhance safety, reliability, and lifespan.
For Scalability, Which Brand Is Better: GoodWe or Sungrow?
GoodWe batteries can scale up to 32.4 kWh, making them ideal for larger homes with higher energy storage requirements. Sungrow is more geared towards residential use, so its designs are compact to fit into bespoke setups and come in slightly smaller capacities, offering greater flexibility to increase energy availability while maintaining high efficiency.
Which Battery Is Best for a Small Home?
Depending on your needs, Sungrow offers affordable, reliable solutions, while GoodWe balances cost and performance. GoodWe can be a solid option if you want a system from the ground up, while Sungrow offers small units for greater flexibility in meeting your energy needs, which may be lower in a small home.
