Yesterday evening after dark I was watching a streaming show on the internet. Suddenly the dim fluorescent lights in the tv room started to flicker wildly, and then went dark. I don't recall if the tv went dark when the flickering started or when the lights went dark. After maybe ten seconds (not sure at all) all the power came back on, but I had no internet. The local neighborhood remained dark. I tried connecting to the internet again a short while later. I was connected to my wi-fi, but there was no connectivity.

My A/C does not have soft-start so maybe if it tried to start it could have caused the flickering. But the internet outage seemed to coincide exactly with the flickering, and what are the chances the A/C tried to start just at the moment the grid and internet went down? My system is supposed to switch over so quickly that if the A/C were running it would not even notice the grid going down. And anyway, I don't think it was running because when I went to shut it off at the thermostat it was off at the moment.

I'm wondering why the flickering, since the system is supposed to switch so quickly.

I'm also really happy that I have the Powerwalls. I couldn't watch the end of the show or go on-line, but after ten seconds of dark I had power when all my neighbors' houses were dark. This morning my Powerwalls are at 60% which is normal or a bit higher than normal pre-dawn, since the outage shut off my A/C an hour or two earlier than I'd have shut it off normally. Ceiling fans are not as good as A/C but my neighbors would not have had even that. Thank you Tesla. But I'm still wondering about the flickering.
