But engine speed will affect voltage. At least on older units.

Not sure what the generator is but most have the ability to adjust the
output voltage and frequency. If you have the option you could just crank
the generator output voltage up enough to make the UPS happy. Note that is
done by adjusting the excitation voltage, not the speed of the engine.
Engine speed changes frequency. (All of this assumes a traditional
generator, not a inverter style generator like the small Honda’s)

So Friday we have another 3 phase go down in the building. They unplugged
it all so that wing had nothing.
As a precaution I start up the generator. When they're cutting the other
phases we are using I move it to the generator. The generator complains
and the UPS units don't switch over. I drop it to say 90% open choke and
the UPS switches over - but it's only 110v. I'd like to know what's going
on here.
I have 175 feet of 10 gauge (times 2). Two circuits on the generator, two
runs of copper, two UPS. UPS is doing about 5-6 amps each.
What can I do better? Should I? It runs but I'd like to keep it as
simple as possible to avoid "teaching someone" to lower it from full open
choke.
