Chuck, exactly where Magnum didn't think before they wrote. My guess is they assumed the generator would be sized for the same critical loads as those supported by the inverter. But they didn't say that or any other comment about the generator. Sometimes, far too often, you have to understand the function or at the very least assume everything written is just an example. BTW, their reference to the generator isn't relative to the shore cord setting. I'm not sure where you read that. What I do know is you have to be careful reading the manual that's for both the dual input hybrid versions and single input units.
