Battery and solar inverter in one enclosure
The third generation integrates a high-power solar inverter directly into the battery, removing a conversion stage, cutting installed hardware and delivering 11.5 kW continuous output.
In Powerwall 3, solar arrives as DC and charges the battery as DC. Eliminating the DC→AC→DC round trip of an AC-coupled system recovers several percentage points of annual yield and removes a separate string inverter from the wall.
11.5 kW of continuous output is enough to run air conditioning, induction cooking, heat pumps and an EV charger simultaneously on most homes, so backup no longer means a reduced 'essential loads' panel.
Powerwall 3 is the default for new solar installations. Powerwall 2 remains the right answer when retrofitting a home that already has a healthy string inverter, or where multiple smaller units suit the electrical layout better.
