New polar cub Mach 8 AC and the Honda eu2000i question

2200i and Mach 8 here. So far, so good. Have not tried it at altitude yet, so MicroAir might yet be needed..
I have no experience with lithium, but 950 sounds like a lot. Convertors generally provide a variable load as battery state of charge and and dc loads dictate. Since my ability to carry gasoline is limited, I shut off the convertor and switch the fridge to propane. These are my only two AC loads.
