I gave up on the small inverter for small things and the big inverter for big things business after a few years of that. (Posted about how that was a false saving a while back--with figures to show that.)
EG, my reading light is a CFL bulb in one of the 120v wall lamps. Using the 3000w inverter, this lamp causes a draw of 1 amp as seen on the Trimetric. That beats the 3 amps the regular 12v light draws and that CFL gives more light. (I don't need a bunch of LEDs instead, thanks)
Not the best example. You have a fat energy budget - fed in part by generator, but this is another story. With 3000W machine always on (for 120V lights etc), there is quite a lot of idle draw, the OP is trying to avoid such a scenario.
They only need inverter for intermittent use of 110V loads. PSW is needed for small things, so it could be small - but hair drier necessitates at least 800-1000W, and it's easier to have just one inverter. They don't need 3000W because there will be no loads anywhere close to this limit and no big battery bank to support it.
