The most recognised home battery in the world. The Tesla Powerwall 3 stores 13.5 kWh and integrates a hybrid inverter with 11.5 kW of continuous output — enough to back up an entire home, not just a few circuits.
Why it stands out
It charges from solar, shifts your consumption into cheaper tariff windows, and powers straight through outages with automatic, seamless switchover. Tesla’s app and software are the benchmark for the category, and up to four units combine for 54 kWh of whole-home capacity.
