My wife and I have had our 6.3kW system with a Powerwall 2 for almost a year now. In this (we will call it) year, power has gone out quite a few times for short periods of time, but generally it's been while we weren't home. Well, since December we've had the power drop out for an hour and a half in December and then a short stint of a few minutes a few days ago that we were home for. Now, in our house, I have a few things hooked up to individual backups as well. These are things like our modems, routers, TV, and PC. These are Cyberpower battery backups plugged directly into the wall. Well, both times we've been home, we noticed that the battery backups are thinking they lost power from the wall and causing them to run on their battery! The power is running on backup, our lights are on, other outlets that are not on the Cyberpower battery backup are working FINE. But the Cyberpower units will not notice that there is still power coming from the wall. As soon as it swapped from grid/solar power to the Powerwall, the Cyberpower units would switch to their battery. I have tried unplugging the units, but it's as though that outlet is dead to them. But then I'd plug in a light and BOOM. There is power there! We wanted to keep our individual battery backups working so that if and when the Powerwall runs out of juice during a longer outage, we can keep our internet running as long as possible. Do you guys think it has to do more with the Cyberpower units or the Powerwall feature? The Cyberpower units are probably nearing the end of their life in general (I think they're about 5 years old each) and I'm thinking of getting new ones anyways. But I don't want to if I'm going to run into the same issue as before. Let me know if you guys need any additional info. I'm happy to provide additional specs. Thanks!
