How long is the battery backup likely to run for?
Given that you have a generator with a manual cutover, all you need the
battery to provide power for is long enough to get the generator started
up. Power the battery backup with the generator if/when the power cuts
out, and let the battery backup keep things running until the generator
You can significantly reduce the load on the battery backup by turning
off any monitor (and other peripherals) if/when the power cuts out.
I have a couple of UPSes in my setup here (I usually don't need them, but
they're nice to have on the rare occasions the power goes out here), and
when the power does go out, I come into my office and shut down all non-
essential systems and turn off the monitors. I have a couple of portable
battery-powered chargers for phones/tablets and such, so I don't plug
those devices into the UPS at all when the power's out.
Also, what operating system is in use? Some do a better job of providing
recoverability than others if the process is interrupted.
