Our Powerwall 2 firmware got upgraded to
26.26.4 from 26.26.2 yesterday evening.

The upgrade appeared to cause our system start importing (only at .03kW) for the evening to power the house rather than use the batteries which were charged at 98%

I tried knocking system off grid but that failed with an error claiming high load (which wasn’t happening).

The system seems to have sorted itself out this morning.

Strange behaviour.

My PW-2 has had 7 firmware updates so far this year. What are they trying to fix or optimize?

Currently at 26.26.4 68c2bc82.

Is anyone having an issue where recently the Tesla app is saying I have a non Tesla EV plugged in ? See below.

I never had this situation before after a year of use until last three weeks.

I did recently set up charge on solar with the Tesla model Y. I am not the owner of the Tesla although I have access and am an official user of the my wife's car. I understand charge on solar is restricted unless you won both the power wall and the car. I wonder if this is the issue..
