The trouble with using a UPS is they generally are not meant for long term use- at the very least I imagine they would overheat.
I just meant trying to use a ups as an inverter for long term use is not a good idea. As you say, they are meant for orderly shutdown, not hour after hour of inverting.
I should qualify this to specify inexpensive UPSs- large, expensive online UPSs are a whole different ball game.
I know some industrial UPSs DON'T carry the load but are able to cycle match very quickly so equipment doesn't notice when the mains go off.
Nope- they use transfer relays. Because I have disabled all of the alarms, now I just hear all of the relays kick over when there is a power glitch. Mine also buzz while operating on battery.
I should add that I only have experience with the APC Backups series and Cyberpower- basically whatever is on sale of Office Depot.
