Why did my computer (on a UPS and generator) crash!?

We are having a power outage.  I have the computer on a UPS and a whole house generator.  Everything worked normally; UPS kept the computer powered, and the generator kicked in 30 seconds later.


The computer just crashed.  I think I know why, but would like some confirmation.


My freezer is not on a generator powered circuit.  After 3 hours I figured it would be good to get some electricity to it.  The closest powered outlet happened to be the UPS.  I plugged it into a battery powered outlet on the UPS rather then a surge protected only outlet; didn't think it mattered.  It was fine for a while, and then the computer crashed.  I am thinking that the freezer came on and needed more power than the UPS could deliver, so the UPS tripped out.  I am surprised the UPS capacity mattered when it was on the generator, but have no other explanation.


Does that make sense, or should I look further for a problem.

A UPS has load limits, regardless of the incoming power. As well, a UPS does not tend to like motors, which have a very high startup current, although for a brief period of time.


So, yes, that makes sense.
