Tried that.
Threw the breakers for the 4 PowerWalls and solar panels - and the breaker inside the TEG panel which disconnects the grid power. Waited for 10 minutes - and then powered the TEG and reset the breakers for the solar panels and PowerWalls.
The PowerWalls won't turn on - all 4 have their LEDs black.
It appears they may be looked for a 12V signal over the CAN bus from the TEG before they'll power up.
Tesla and our local tech believe the PowerWalls are likely between 75-100% charged - based on the home/grid power logs before and after they went offline.
The local tech also tried disconnecting all 4 PowerWalls from the CAN bus - and connect only one at a time - just in case one of the PowerWalls was causing this problem. And that didn't have any impact.
I plan to call Tesla tomorrow - check on the status of the replacement board (since it was supposed to be shipped by now) - and if they believe there is a firmware update coming that could fix this without the board swap.
