Therein lies the problem. There is no switching at the OUTPUT of the inverter. The inverter calls for generator and then takes power from the generator into itself. It may pass generator power on to the loads but that is only incidental. The inverter does not switch BETWEEN itself and anything else. The inverter is always the "source".
This thread is about the place of the N-G bond, GES etc. on an off grid system. Some postulated that it maybe should be at the generator.
I thought of another analogy for this. If the generator is a valid place for the N-G bond then the solar array would also be a valid place. But this would be ridiculous. The generator, solar array, some water wheel, are all auxiliary sources that feed into the inverter (or battery system) but the inverter is the one thing that is always there, always running, always required.
