I thought I would post my experience with my set up since there has been a lot of talk about it during the recent snow storm.
The exact equipment I used is in my sig.
The only thing plugged into my UPS is the pellet stove. It was running on low when I unplugged the UPS. The UPS kicked on and the pellet stove didn't miss a beat. I then plugged it in to my generator which took about 10 pulls to start. UPS shut off and was back "online". The voltage fluctuated between 122/121. Hertz output was always 60. After about 5 minutes I plugged in another fan..one of those floor drying type units. Voltage stayed constant at 121..UPS did not kick on. Then about 5 minutes later the UPS kicked on....Hmmmm...generator stalled. Then ran another 30 minutes without incident.
No sure why the generator stalled but the gas is a little old and maybe it did not warm up long enough. I hear its better to run generators frequently so I plan on doing a 30 minute run every other week.
Hope this helps.
Edit: Building wiring fault light is on on the UPS?? Not sure if this is something it would do with all generators
