i think we are drifting off topic
the question was not "run a/c from inverter"
the question was about load support from inverter to 'START' a/c using smaller generator. large enough for run load but not large enough for reliable starting surge
and i think the magnum 40 amp 120vac surge support, should be enough for any RV roof top a/c than can run from the generator
after all the 40amps from the inverter is in addition to the generator power, as long as it is load support such as the magnum which syncs to the input power
situation with inverters where it switches to inverter for start and then back to generator
would be limited to the max the inverter can supply
battery bank size has little to do with 'start only' support
as long as it can supply the needed boost for a few seconds
as PT found out tricking the inverter into continuous support is Not good
better off doing double conversion and running directly from the inverter
with enough inverter to do the job safely, and charging the bank with however much wattage can be mustered
