gpez points out some important consideration with the different type's of UPS models.
Another very important consideration is the type of output waveform.
the less expensive UPS models output a modified square wave instead of a true sinusoidal waveform.
less tolerant devices may suffer from non sinusoidal inputs
Here is a good link with examples:
Database of UPS inverter output waveforms
