@pianotuna I finally installed the micro-air 364 on to my Carrier Air V 15k air conditioner. I'm in campground hooked up to 50a service, completed the 5 learning cycles. It was interesting to watch the me-arc display in the ac input screen, the air conditioner fan would run for a couple minutes then I could see 3-4a load coming in for 60 +/- seconds then quickly climb to roughly 18a then settle at 14a.
Here are the test that I did. While still plugged into the pedestal I turned the load share down 15a, 10a, 5a and turning the air conditioner off for a couple minutes between each lowering and at no time did the ac unit stumble or did a red fault light show on the me-arc.
Then I disconnected the the power from the pedestal and connected it to the eu2200i generator setting the load support to 15a and 10a, same results no red fault light on the me-arc and no "overload" or stumble on the generator. Also I'm in tree cover/ overcast so little to no solar was helping.
I didn't try the ac unit on just batteries but I'll bet there shouldn't be a problem especially if solar is contributing. In a couple weeks when I'm back at boondocking I'll update those results.
Maybe with the lfp batteries that's the difference that I'm not getting the fault lights on the hybrid inverter or stumble in the ac unit or generator. ;)
