So you trick your APCs into allowing dirty power through to your
equipment? ;-) I'm trying to avoid doing that.

On Wed,
I am not sure exactly what you are getting at by using the term alternator.
But a good option is any of the honda or yamaha inverter generators. These
have a DC generator system running a power inverter so the power output is
much more constant. They are also quieter and more fuel efficient
I'm looking at inverters as a solution.
We have several generators (they increase throttle based on load and
generally have very unclean power).
We also have one Sear Alternator that runs at a constant RPM and
provides some of the cleanest power I've ever seen. 60Hz on the nose @
120volts.
Do you have equipment that is very sensitive to frequency? Most newer stuff
uses switch-mode supplies which typically can operate fine over a wide
range of voltages and frequencies.

Not that I've noticed -- it all runs fine when we plug it into the
generator directly -- but why chance it?

Why spend money to fix a problem that's not a problem?
Always two ways to look at things!
My point is that turning down the UPS sensitivity is a fine solution if the
equipment runs ok on the generator.

Perhaps My concern is what that may do to the clamping ability of
the UPS during regular operations?

We've noticed that our cheap generators won't charge the UPSs back up without
some extra load to stabilize things. To provide that load we include a 500w or
1000w halogen construction light with each generator kit. Plug the light in and
the voltage stabilizes, which allows the UPS to kick back
Now that is a creative solution!
That's exactly the problem -- I believe. The generators don't have
enough load with the small pull the WISP equipment has.

You probably want something like this:

Go straight to the battery. Monitor closely. The honda and other model
inverter generators usually only put out a small amount of amperage via
DC only.

Especially with those small, cheap 2-cycle, 800-1000W generators, a
200-400W light stabilizes it well.

The other option I've used is to use one of the tripplite online UPS'es
which have a *Very wide* input frequency range. Because it's online, it
will take the power from the gen, and then clean it up to the right
frequency for the load.

Alternatively, run your equipment on DC from an Iota DLS charger, which is
constantly trickle charging some batteries. When the power goes out, it
will run a lot longer because you're not converting (like a UPS) from DC
coming out of your batteries to AC and then converting from AC back to DC
