Tesla Powerwall › gateway control board and firmware
Gateway briefly cuts house power for no outage
reported in the field
Symptoms
- The house loses power for a few seconds to a minute or more, or switches to battery-only, while the grid is up and neighbors are unaffected
- Often coincides with heavy loads (EV charging, a large combined solar+Powerwall setup, a second independent gateway on the same property) or a brief unnoticed grid dip
- Tesla's own explanations vary (surge, overload, line impedance) and are often not confirmed
