Combining Systems with Powerwall
Powerwall & Solar
Powerwall can be integrated with a new or existing solar system. Adding Powerwall to your solar is the best way to maximise your system’s value – allowing you to use solar power day and night.
To ensure reliable operation during power outages, at least one Powerwall is required for each 5 kW AC of solar included in the backup circuit.
Powerwall & the Grid
When Powerwall is installed without solar, it can charge from the grid to support Backup-only Mode. Powerwall installations must also comply with local rules around grid charging.
Though Powerwall can operate when the grid is down, Powerwall must still be connected to the grid.
Powerwall & Other Batteries
Powerwall does not currently work with existing battery systems.
Powerwall & Other Renewables
Powerwall does not currently integrate with other renewable energy sources, such as wind or hydro.
Powerwall & EV Charging
Powerwall can provide stored solar energy to your EV through your home electrical panel. However, there is no direct connection between Powerwall and the EV wall connector.
