Hi, I have four PowerWall +. I lost power yesterday and my power walls stopped operating. My energy consumption at that time was very small and the PowerWall’s were almost fully charged. The only major appliance operating was a dishwasher. When power was restored about 1/2 hour later, the PowerWall started operating again. Called Tesla online and was told that I had experienced a power surge probably due to some appliance that was operating at the time of the outage. As I recall, the surge magnitude was said to be around 30 A. Given that I have four PowerWall’s this explanation seems doubtful. Is it possible that there is some setting on the PowerWalls that is incorrect? Thanks.
