My powerwalls started cutting power to my house tonight. It did this several times and when it did it would take several seconds for the power to come back on. I was the only house in my neighborhood to experience this. Normally when I simulate a power outage all I get is maybe a light flickering. I called Tesla support was was told that if the gateway detects an over power of lower power it will cut-over to the battery. When I asked about why it took so long to cut over she said you may be over powering the powerwalls. But I don't understand how that would happen as there was only a couple of lights, a couple of computers, and 2 TV's on. When I checked it said I was using 2.1KW of power and I have 3 powerwalls. I also have 11.5KW of solar but it was at night so that shouldn't play into this. Is this normal?
