GordonThree, that is an interesting situation. The PM 100amper is PF corrected so it can run on a 15a circuit but I am not sure how much it actually draws in VA. It might well be too much for a 2000w generator. You can't set a 120v amp limit on it like you can with the charger portion of your inverter/charger either.
Not clear if that is what the trouble is when your inverter takes over from the gen when the 120v load gets a high surge. If so, then a lower amp charger might be necessary that can run from the 2000w or it will just pop the gen's breaker instead of running the charger as intended.
I am unclear as to how you get the generator to be on when one of these episodes happen. It is not like being on shore power. Anyway, there must be a way to get it all to work.
