Generator Integration

 

How would Powerwall be installed with a backup generator?

Powerwall can be added to an existing system that has solar panels and a backup generator connected with an external Automatic Transfer Switch (ATS) or Manual Transfer Switch (MTS). Powerwall is installed between the electrical service entrance and the transfer switch, where it charges from solar while the grid is operational.

How does Powerwall work with an existing backup generator?

In an outage, Powerwall responds immediately and provides backup power before the ATS is able to detect the outage. The ATS switches to the generator only when the Powerwall state of charge drops below a set threshold, or if loads exceed Powerwall's maximum output.  When grid power returns, the ATS turns off the generator and Powerwall can again charge from solar. If Powerwall is installed with an MTS, manual operation of the switch is required to power the home with the generator.

Can my generator charge Powerwall?

Powerwall does not currently have the ability to charge from a generator. Please stay tuned for future updates.

Does Powerwall work with existing battery systems?

Powerwall does not currently have the ability to work with existing battery systems. Please stay tuned for future updates.

I have a wind turbine/hydro turbine. Can I charge Powerwall with it?

Powerwall does not currently integrate with other renewable generation equipment. Please stay tuned for future updates.
