"Inverter" Generator??

[larrym]

In the portable generator world, I see what's referred to as an Inverter Generator. What's the difference between that and a run of the mill generator?

I ordered my 3750FL Big Sky with generator prep, for an added $695.00, what all does that include? The dealer doesn't know, except to say it has the control panel inside the unit. I assumed it had everything needed to install and run a standard portable generator, including an "inverter" if it was needed.

Thanks, Larry
