How well do those units deal with poor quality power from an emergency 
generator? I have a Champi8on 100296 dual fuel generator. When I'm 
running it, my UPS boxes won't run. They reject the power from the 
generator. I'm guessing it's because it's not 60 HZ, but something close 
enough that it's good for all the rest of the appliances, but not the 
UPS boxes.
