We've seen that too, running an (industrial) 120v garage door opener,
pulled one leg out of phase/voltage enough with the starting current
that the control board shutdown the generator (15kw diesel). It ran a
5ton 240v AC unit cycling on and off just fine.

Using 240V AC may help with that.
We had trouble where the generator had way more load on one hot leg
than the other. It ran rough and stalled often.

The only reason you might have trouble is the air conditioning
starting load. I have seen them cause a generator to stall and die
before.

We're shopping for a generator for one of our larger POP's. The
electrical contractor is recommending this:
https://www.generac.com/all-products/generators/home-backup-generators/guardian-series/22kw-7043-whole-house-switch-wifi-enabled
This would be supporting 4 30A circuits (powering 4 APC UPS) that
are currently drawing about 30A between them (powering network gear
and servers). There is also one of the on-wall indoor/outdoor air
conditioners in this room - unsure what it's drawing.
The contractor also seems to think that this generator, with a
second transfer switch can power the remainder of the small building
which includes some lighting, a refrigerator and some small
electronics like PC's, etc.
Can someone who actually knows something about generators and this
kind of stuff give me some advice here? Will this generator support
our load and not fall over?
Thanks!
