Tesla Powerwall 3
The most complete home battery solution available. Built-in solar inverter, whole-home backup, and one of the best energy apps on the market.
Why We Recommend the Powerwall 3
The Tesla Powerwall 3 is the most complete home battery solution available in Australia. Unlike most battery systems that require a separate solar inverter, the Powerwall 3 has one built in — simplifying installation and reducing the number of components on your wall.
With 13.5 kWh of storage and up to 10 kW of continuous power, it can run more appliances simultaneously than most competing systems. Whole-home backup is standard, and the Tesla app makes it easy to monitor your energy use, set preferences, and track savings.
It's the right choice for SA homeowners who want a simple, powerful, and reliable battery from a globally recognised manufacturer.
