@pianotuna I'll update about the solar panels running the AC in a month or so. I had to go into an rv park in Montana so I ordered the Micro-Air easy start . I'll install it and run the 5 learning cycles while I have pedestal power. This camp is heavily treed and I'll have to wait for a test run with solar for the results.;)

Itinerant1,

Magnum doesn't recommend running air conditioners on the 3000 watt hybrid inverter/chargers.

Mine is a Dometic 13500, equipped with microair.

I've tried everything I can to make it possible, but the red over load on the remote comes on.

I can run the roof air on the Magnum, but it doesn't like it. red light

I can run the roof air with Magnum on load support from the generator. red light

I can run the roof air directly from the generator.

I tried putting the autoformer between the generator and the shore power cord--but I had limited the Magnum to 24 amps input. That failed to run the roof air.

This summer, if we get out of lock down, I'll try again with the autoformer and the Magnum opened up on input to say 30 amps. That's about 2 amps greater than the surge value on the Yamaha generator. If that doesn't work then I'll set it for 50 amps and see what happens.

May you have better luck with the LI batteries and larger solar system, than I have.

If I ever have to replace the Magnum, I'll go to either Victron or Outback.

I use load support a great deal.

It seems that you have put it to the test and the results are not great. Maybe with load support, eu2200i and solar.

Last year when I was exercising my older eu2000i generator and was getting good sun on the panels, there was 160a being dumped into the lfp batteries. I'm hoping now that with easy start a eu2200i and solar I don't get the red light. I'll let you know the results.

Victron seems very impressive and that would probably be what I would go with if starting from scratch again but haven't done any hardcore homework on it, for what I have used my system for the past 4 years living off of it I am very satisfied but having the AC would be nice and if it doesn't happen it won't be the end of the world seeing we have survived this long without it.
