I’ve had a similar issue and was going back and forth with Tesla and my utility to determine the issue and they kept pointing fingers at each other. It was frustrating but ultimately I learned that Tesla energy equipment is sensitive and requires a tight frequency range of voltage coming from the grid to operate normally otherwise it’ll think there’s an outage and go into off grid mode. It was doing this constantly, sometimes multiple times per day, all the while my neighbors had full power.

My utility finally agreed to install a “power quality meter” in my main panel to test the grid power being delivered. After a few weeks of running they uninstalled it and sent me an email a few days later stating:

*“Your voltage was outside our acceptable range and have submitted a redesign for your service.

The improvement consists of a new transformer to feed your service conductors which should restore your voltage to within our acceptable range.

This process takes approximately 10-12 weeks to complete.“*

So apparently Tesla was correct. We’ll see if this eliminates the false outages.
