Between my brothe and I we have installed the micro air on two units, One a coleman MachIII 13.5KBTU the other a dometic 13.5K BTU. In both cases with a honda 2000 in eco mode, both AC's will easily start on the honda 2000 even up above 5000 ft. But then they will overload after a bit. The honda 2000 seems to be good to about 3500ft. Now on both units the honda 2200 will start and run them on a hot day at 5000ft plus. In once case it was run several times at 7,000ft. the micro air will detect impeding overload and kick out the load if it thinks it is close to overload. On occasion at 7000ft and 90F or so it would kick out once, then come back on and run for hours.

The honda 2200 has two advantages, 200more VA, but more importantly a much larger engine so less affected by altitude. BTW the honda's were jetted for sea level, not high altitude.

Thanks for the detailed info. Our new EU2200i just arrived a few days ago. Got our fingers crossed we get similar results. BTW, in your previous post ref inrush current with the Micro Air, what did you use to measure it?

Tektronix clamp on hall effect current meter with peak hold and then later did a check with a Tek digital storage scope and Tek ac current probe. The Peak hold IIRC will catch peaks on the order of a few milliseconds. Did the measurement with the scope just to verify the peak capability of the clamp on meter for future use.


My results were consistent with the micro air claims. I think The key is to follow the learning instructions exactly. It's best if let the system learn on a good stiff power source, like your home service on as big a line as you can get to minimize voltage drop during turn on. I used my 30A feed I had wired in the house for the trailer.
