The generator has a floating neutral and you need an adapter to make it a bonded neutral. That will work for 120v. The bonded neutral adapter in a 120v outlet will most likely bond the 240v. I made an adapter for my Eu2200i. Here’s an explanation.

Inverter is essential as is 240V with a 50 AMP NEMA plug.
Doesn't mean the generator will produce 50 AMPS, but both legs energized doubles the rate of charge I think. I vaguely remember anything since suffering a stroke.

Harbor Freight is about to release a 11.500 W inverter closed-frame any day now.
I'll be the first to buy one.

When we take our next lap around the USA pulling a travel trailer it'll be in the bed of the Sierra for charging where their is no charging.
No range nor broken charger anxiety for this driver.

A long stroke engine with the lowest RPM usually means a low exhaust note and quieter with the generators on the market now or at least last I was checking them out and buying.

I love electricity and own dozens of generators purely because I like them.

When the recent fires hit a 6 mile radius around us was blacked out for the better part of a week.
With our Starlink and Tesla solar and Powerwall we were good to go.
100 Gallons of gasoline on hand and loaned out generators our neighbors were good to go to.

I have a 2-71 Detroit Diesel that was used on a generator. I’d like to find a generator head and charge my truck with it.
