Compatibility summary

The Tesla Powerwall 3 fully runs 50 of 50 loads on North American power and 53 of 53 on 230 V UK/EU/AU power.

The Tesla Powerwall 3 is a permanently installed hybrid battery. It sits behind a gateway or system controller, so loads are fed from the home's own panel rather than from outlets on the unit.

With 13,500 Wh of storage and 85% inverter efficiency, the unit delivers about 11,475 Wh of usable AC energy — enough for 8.5 days of a full-size refrigerator, or 7.7 hrs of a 1,500 W space heater. Its 20,000 W solar input refills it in roughly 51 min of strong sun.
