Powerwall switched itself back ongrid this morning

[CrazyRabbit]

i don't know if this is firmware upgrade related, but i went off grid as thunder storms were rolling in last night, and around 6:00 am the system switched its self back online.
what would cause this to happen, powerwall was at 79%, discharged 20.4 kwh over night.
system didn't reboot: "up_time_seconds":"89h37m24.249736177s"

Alerts: perhaps normal

Based on the alert titles only my WAG is that there was a glitch on the CANbus and the powerwalls lost communication with the gateway momentarily.

that is my thought too. do i need to contact tesla, pending problem?
i checked my cameras looking for a utility power glitch at 6:16am and didn't see anything, i can see the lights of the houses behind me that are on the same transformer...

Hmmm. My guess is that it is worth telling Tesla, so that if the issue recurs, you can waive off the "well it isn't an issue because it only happened once..."

The canbus connectors are pretty solid, but they have to be locally wired, so I think that there is the potential for human errors, loose wires, etc. You could go pop your covers and look for obviously loose items, or wiggle the wires into the connectors to see if anything happens...

All the best,
