Electrical Management Systems questions
I'm considering installing a hard wired EMS. I recently saw a thread, that I can't find again, that implied these EMS systems will not work with an inverter generator supplying the trailer. I real...

I don't see the reason to use an EMS downstream from the generator. You already know the voltage from the generator. The generator would stall out before voltage became too low.
There is also my pet peeve about EMS. The low voltage disconnect is far too low. I'm not comfortable with running the roof air below 107 volts.
Because generators, being made by man, can and do fail. I don't want the electronics in my RV subject to the generator failing in a GOOD way. Murphy's law says that would not happen for me. It is too easy to let the EMS protect from a generator too.
As far as the generator stalling out before the voltage becomes too low, you are betting your electronics on that. I am not. What if the generator fails by providing voltage that is too high? What if the generator fails by providing power that is not 60Hz +/-?
