I feel more comfortable pairing a set of Eu2000i's for running my Dometic 13.5K Btu AC unit. Most of the time, though, I am at higher elevations where AC is not necessary... my Diesel motor did the work instead hauling everything else up the mountain. I get all of it back when I go down hill.
I do run my Eu2000i genny a bit hard running the microwave, but that is rarely over 7 or 8 minutes a shot.Warm the gennie up, then run the microwave. Always warm the motor up before putting in under heavy load, for at least 3 minutes.
