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.
