I have a new Champion 3500 inverter generator and a newly installed SurgeGuard 50A hard-wired surge protector. Upon connecting the generator, it would charge the batteries and power the ceiling fan (after the SurgeGuard start-up delay)
This statement definitively says you do not need a G-N bonding plug. If you did it would not have powered anything at all.

but when I tried the 15K A/C, the SurgeGuard faulted and cut power. Tried another approx 15 times, some with AC and some without (no load, only batteries charging). With the AC, usually it would run 3-5 seconds before the SurgeGuard would fault. With no load, the SurgeGuard faulted instantly sometimes and others times it would not fault and continue to charge batteries.
This is classic low voltage cutoff. You need more generator to run that A/C.
An alternative if you don't mind spending about $300 is to install a
MicroAir Easy Start module in your A/C. While I don't have one (as I don't have a generator) it has excellent reviews on every forum I read.
