You need to be a bit careful with this approach. I've had trouble in the past
running one UPS off of a second one - the one downstream thought the power
wasn't
clean enough to come off of battery. I was assume it would have a similarly
difficult time running off of an inverter (which is essentially the output end
of a
UPS).
This was for an attempt (successful, I might add) to transport some computer
equipment without shutting it down for more than a minute.
