Powerwall 3 solar inverter
Integrated into Powerwall 3
Solar conversion and battery storage in one Powerwall.
Solar and storage, together.
Powerwall 3 has its solar inverter built in. Solar panels connect directly to the unit, combining solar production, battery storage and backup in one system.
One system for solar and storage
The built-in inverter converts solar power for your home. The battery stores energy for later use.
No separate Tesla Solar Inverter needed
A new Powerwall 3 solar installation uses its integrated inverter. Tesla’s standalone Solar Inverter is a different option.
