I think You are hitting the limits
Cooler temps mean higher charging voltages for lead batteries (AGM is lead)
When you did the power supply test, supply voyage was lower, the battery was under load, the combine converter & battery voltage level was probably barely above 13v maybe less
13*75 is less than 14.× * 75
Which means a different VA loading on the generator
92 Oct non ethanol may help, warmer weather may help
A bigger generator or smaller charger WILL help
So you use the battery voltage for "output watts" and not the voltage set on the charger. That would make the required input VA different for the same output amps.
I need to do a Kill-A-Watt while battery charging and compare results.
I have a 75 and a 55 to choose from. Probably should have the 65 amper and no worries. The 55 is more gen time than the 75 but it gets it done (eventually).
