Hi
 For the square wave inverters, they have a flat line
square wave of 115V RMS and peak.
 AC rectification as seen on most switchers use
a simple voltage doubler that doubles the peak voltage
that is around 160v on a sinewave. This means that
if the inverter was intended t run lights, it will
have too low a voltage for a switcher input. If
it was intended for a switcher input, it would burn
the lights at too high of a voltage.
 Swithcers don't like to run at low voltage.
