There are devices for RV's to lessen the load when the RV A/C starts
up. Sounds like a good adaption for these A/C units.

I have seen backup generators actually stalled out when attempting to
start two bard AC units on a telecom shelter. That is what happens
when a guy goes cheap on the generator sizing. Sure it would pull the
running load just fine.
I had to develop some kind of circuit to not start the AC until the
gen had been running for a while. I think I also did something to
prevent them from both operating during a power outage.

Most of the new ones are AC Variable speed drives. The drive
rectifies the incoming power into about 350V DC before converting it
back to a variable frequency AC to drive the compressor at whatever
speed it needs. Good drives could care less what the incoming power
looks like since all they are doing is turning it into DC through a
big rectifier. Now what feeds back to the power line from the drive
can be really ugly but that’s a different subject.
Biggest issue with the older geothermal was the compressor inrush
current was high. You needed a pretty substantial generator to get
them started.

My brother has a geothermal heating\cooling system. The primary
reason he got a generator was to run the geothermal system.
The people that sold the geothermal system to him told him that he
shouldn't run the geothermal system on the generator.
Why would this be?
Could he purchase a line conditioner of some sort to clean the power
before it gets to the geothermal system?
I'm not sure of the size, but it's one of those Bobcat portable
welder\generators and he hooks it up to a transfer switch at the
meter for his farm.
