Anyone heard of Semi Pure Sine Wave inverters? Ebay #Item number:   290418862632 link:

Will these run a AC unit?

My gut tells me it's a new name for modified sine wave cause I can't identify the wave pattern in any of my old books the way they describe it.

With no published specs on the waveform, I would say this is marketing double-talk for MSW.

Also note that this one is a 240-volt unit, so it won't be useful to run anything else in your coach.

Lastly, the stacking capability as shown in their diagrams is against code in the US.  Stacked inverters must be hard-wire models, not plug-and-cord models.  For that matter, plug-and-cord models are really not suitable for use in conversions since they may not be hard-wired into anything, which limits them to being installed within cord-length of whatever needs to be powered.
