Tesla Powerwall 3 is an integrated home battery and solar inverter system designed to help you make better use of the energy your solar panels generate. With 13.5 kWh of usable storage, it stores surplus solar power during the day so you can use it after sunset or when household electricity demand increases. This helps reduce reliance on grid electricity and gives you greater control over how your home uses energy.

Its built-in solar inverter supports up to 20 kW of solar input, combining solar conversion and battery storage in one unit. With continuous AC output of up to 11.04 kW, depending on configuration, Powerwall 3 can support multiple household appliances. When installed with Backup Gateway 2 and suitable backup wiring, it can provide whole-home or selected-circuit backup during an outage. Backup duration depends on battery charge and the appliances running.

The Tesla App brings monitoring and control together, allowing you to view energy production, storage and consumption and adjust settings to suit your household. Designed for indoor or outdoor installation, Powerwall 3 supports wall or floor mounting. Compatible expansion units also allow you to increase storage capacity as your energy needs grow.
