Honda 2000I versus Cpe 2000 inverter
I just weigh a Honda with full gas tank 53.2# Also weigh my cpe 2000 with full gas tank 55.6# I cannot tell the difference by lifting them For practical purposes they are the same heigh...

You are not likely to be able to run a 75a converter on that gen anyway. You are looking at one that draws about 1600VA at the most.
You could try known Non-PF loads (PF = 1) to see what watts you can stand to listen to, call that the VA, then you can work the math back to see what that would come to as battery voltage and amps for converter output.
Say an appliance that draws 1500w is too loud, but 1000w is ok. PF is 1, so VA is 1000 for what you can stand. PF of typical converter is 0.7, so input watts will be 700w. With typical 85% efficiency, that would be 595w output.
Say you want the batts to be at 14.8v Vabs, so 595/14.8 = 40.2 amps, so you could likely be ok with a 45 amp charger.
If you could stand the gen running at its 1600, then you could go for
1600 x 0.7 = 1120w input x 85% = 952w output/14.8 = 64.3 amps, so you could run a 60 amper instead of the 45 amper.
BUT--the other thing is how long do you have to stand the noise before the gen slows down? The 45 amper will be at its lower max noise longer than the 60 amper will be at its max noise before amps taper and noise reduces until it is the same as the 45 amper.
With a 220AH bank at 50% SOC, the 60 amper will be at max noise for about 50 minutes before amps taper, while the 45 amper will be at its lesser max noise for about 15 minutes longer, 65 minutes.
