Yes. Exactly. That is where my Trace inverters falls down on the
job... when the voltage warbles. A dead reliable backup PSU, for
someone who doesn't want to damage hardware or risk their system
registry getting corrupted, would involve a line conditioner that
would shut the power down at the first warble, a Trace DR inverter,
and a deep-cycle battery. Then you'd be covered. Anything less, and
it's a crap shoot.
