UPS with less sensitive AVR?
So I recently moved to a new home, I have 3 APC 1500 UPS for some of my stuff, but the issue I’m having is that the voltage input in this new home is around 129-130v. During the day it’s not an issue, because things are being used so it drops down to 125 sometimes less, but at night when I go to sleep, the AVR kicks in on all 3 UPS, which makes all 3 of them start humming.
Is there a way to prevent this? Modify the AVR values? Or is there a UPS I can replace these with that has a less sensitive AVR threshold?
