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 on to the line power.
It also provides some nice lighting if it's at night.

This is the third time in about two years that we've had some major

Every time the situation is the same,
We roll out our portable generators to a few of our smaller sites that
don't have full-time generators -- and every time we have to fight with
them to get clean power out of them -- usually just ending up putting
equipment directly on the generators and bypassing the UPS systems.
I've seen the generators go everywhere from 40Hz to 90Hz.
Has anyone come across a nice portable alternator (as opposed to a
generator) that can be taken to tower sites as supplementary power?
