Have you actually tried it? I bought a marine battery and

I am actually planning to use a 1.5 kw inverter connected to
a Prius.
It can run my frig including start-up.

Any speculations on why the battery/inverter setup failed to run
the furnace?
I have a relatively new furnace, and I don't want its control board
getting clobbered by a few spikes in the genny output.

I'd say it depends on the requirements/sensitivity of the AC device.
Inverters can put out a modified sine wave, sawtooth wave, square wave or
virtually the same wave as the power company. Then there's the quality of
voltage amplitude, frequency and ability to maintain phase. It's always
about the money...how much you pay for the inverter.

Many things will run on crap waves just fine, some run but less
efficient, some run and screw up the device to some extent.

Couple of links to inverter output waveforms.
