Tesla Powerwall 3 Review
The Powerwall 3 doubles the industry standard of delivering only 5 kW of power at any one time with an impressive 11.04 kW AC of continuous power per unit. Because it can store up to 13.5 kWh of energy and begin heavy loads rated up to 185 A LRA, a single unit is sufficient to support the energy needs of most Australian homes.

Frequently Asked Questions
Will a Powerwall run my whole house during a blackout?
It can, but it depends on your loads and how the backup circuits are designed (partial vs whole-home backup). Powerwall 3’s higher output can make whole-home backup easier in some homes, but switchboard design and appliance load still matter.
What is the Tesla battery warranty in Australia?
Tesla’s AU/NZ warranty is 10 years, with 70% capacity retention at 10 years under the stated conditions. Just keep in mind that the system should be connected to the internet so it’s still able to get remote firmware updates (which matters for full warranty support).
Which Tesla battery is best in Australia in 2026?
For most new installs, Powerwall 3 is the stronger option because it can deliver higher continuous power (up to 11.04 kW) while keeping 13.5 kWh usable storage.
Is Powerwall 2 still worth installing?
Unfortunately, the Tesla Powerwall 2 was discontinued in Australia in late 2025.
Do I need solar panels to get a Powerwall?
Powerwall can be used in different operating modes (including time-based control), but the “Best value” use case for most households is pairing it with solar so you’re storing your own generation for night use. The warranty also separates typical home use from “other applications,” so it’s worth matching the system to your intended use.
How much does a Tesla Powerwall 3 cost in Australia?
In Australia, a Tesla Powerwall 3 installation typically costs between $12,500 and $14,500 fully supplied and installed, depending on your specific home switchboard setup and installer fees.
