Does anyone know of a way to get a UPS to trigger a generator to start, and to switch over to the generator power automatically or does this type of thing just not exist?
What Patrick said.
But, on a minor note that probably won't affect your Symmetra but I'm posting in case anyone else here can shed light on.... we had a power event this AM. The transfer switch did it's magic and all was good... Except for two new APC1400's- they failed once the batteries drained. I triple-checked that they were on the right panel, played with sensitivity, even tried daisy-chaining one off a good working 2200. Nothing I did would convince the two 1400s they had power. Once the house power was restored they came back to life and look normal. I later learned that two of our colo customers with APC1400s had the same problem :( Other models (even a couple non-essential lower-end, dumb APC 450s and 650s) didn't blink at the generator power.
It's possible that the generatar is running to fast or slow and the frequency is out of range for the ups... I had this happen in Ghana, generator was producing 47.5hz, opened the throttle and everything was fine.
