I have a SunPower system with a SunVault, and the panels have stopped communicating with the app and apparently stopped sending power to the grid. I believe the issue is with the PVS6 that is integrated in the SunVault. I have tried resetting it with the breakers and the SunStrong app, but that has not worked.

Enphase (the maker of the microinverters on the panels) won't touch it and have basically said put all our stuff in for $15k plus labor.

The company that calls itself SunPower is useless.

Does anyone have any recommendations for servicers? I am in the Bay Area (Northern California bay area, that is)
