Generator/Progressive Industries EMS-LCHW30

With that installed in the camper will I have problems plugging into a Honda or Yamaha generator's 30 amp plug?

Also, should I expect to lose 18% to 27% of a generator's capacity at 6000' to 9000' altitude? Or, put another way, would a thousand watt gen become 750 watts at 9000'?

I'd like to buy a generator, but it's beginning to look as though it's going to take at least 5k to be of much use at our altitudes, and those are pretty darned heavy. Obviously, I'd want to run more than a couple of lights but not necessarily the 15k ac.

    Because of grounding issues, when you plug into the generator you have to switch the EMS into bypass - there's a switch on the remote.

    For a Honda, there are high altitude main jets if this is a problem; of course, changing the jets is a problem, too. I have run my Hoonda 2000i with low altitude main jet at 8000 feet to recharge my trailer batteries with the on board converter and have not had problems.

    We use our generator only to recharge our trailer batteries. If your planned use of a generator is mainly to recharge batteries, I think a 2000 watt generator is plenty; a 1000 watt generator may be a little small for some power converters at high altitude. If you want to run an air conditioner, obviously a much larger generator is required.

    Looks fine to me.
