I have two issues happening at the same time (very much related).
- The APC brand UPS backups in my office all start buzzing at the same time, then click once every 5-10 minutes. This happens at all times of the day.
- If my car is plugged in (Tesla wall charger), the Tesla app starts over when I hear the noise the APCs make. It does this 3 or 4 times, then the car turns the charging off and I get an alert that the charging is interrupted.
Note, I have tried two different chargers and both do the same thing. (One charger is the wall charger, and the other is the charger that is never used that came with the car.)
I have called the electrician and the power company and both parties say that everything is normal. I am having the breaker boxes exchanged out ($5000 later.) This is scheduled, but doubt this is the cause also.
I don't think this was a surge as the second car charger that I use still does the same thing, and it was not plugged in when this problem first started.
What could the issue here be?
