I'm in the midst of a multiple day power outage and my UPS decidedly does not like my backup generator. I thought that was because this is an old generator with a mechanical speed govenor which starts at 62Hz dropping to 60Hz once you get to about 30% load. Having not much else to do, I tried running the UPS when the generator was under load and it still didn't like it. It kept switching on and off battery.
Power outages are not uncommon and, since I'm in a rural area, I'm often at the bottom of the priority list. One and two day outages happen a couple times a year.
Because this is a multiple day outage, I bypassed the UPS so the server rack could come up, but I'd rather just let the UPS carry over the systems until the generator is up and running.
So what are my options here? A double conversion UPS? Some kind of power conditioner? Replacing the generator is not an option (this is a 16KW generator, 66A, 240V at 60Hz)
