I have the 100A version, they make 2.I don't really get the point of the autotransformer. Isn't it limited to 32A on the neutral thus limiting you to 3800w from the 7500w? I can see the point of being able to utilize both of the inverters to charge since each inverter can charge 1700w, but I'm assuming it would be better to disable switch as group so you can run 7500w through the inverters even though only charge 1700w. Also you'd still get the split-phase power in the RV since inverter2 would be inverting.
I'd think it would be better to just get a 2nd charger and plug into the generator. I'm assuming its a QD7500 with single phase and provides a 50 and 20amp built in breaker. Could run the 50a to the main inverter then the 20a to the 2nd charger. Also it'd give you a backup charger just incase any issues.
The Onan 7500 makes ~32A on each leg (Same Phase), the Autotransformer simply changes the legs to 180* out of phase, but in either case, I do have the 100A version of the Autotransformer.
I apologize if I misunderstood your question
