Adding NG Generator to Existing PV & PW2 System

[BIC1]

Thinking about adding a NG generator, such as Generac, to my existing PV & PW2 system. Would that integrate with the existing Tesla Gateway 1 transfer switch or would the generator need its own transfer switch? Thanks.

I would check with local electric company. Also with Tesla. I do believe this would not be possible.

As long as the generator is a backup to the Powerwall backup it will work fine.

On-grid powerwalls are not compatible with charging from a generator.

Search the forum there is some good information here on this subject.

It’s possible. We have it done with GW2. The generator feeds the “backup” panel directly so that it senses when the upstream grid or Powerwall is not providing power and energizes the “backup panel”.

I put backup panel in quotes because it was the 200amp main panel for the home until the Powerwall install where Tesla made that whole panel the backup panel for whole home backup, and a new panel for the GW2 and grid is the new main panel.

I have separate transfer switches for the generator. They are cheap

This Tesla support page briefly describes using a generator with Powerwalls.
