A Micro Air Easy Start, a plastic box with circuitry inside, can reduce inrush current (LRA) as much as 25-40 amps. This is a massive, huge difference in capability.
I have a supco soft start on the AC unit already - which is how, I can get the 2000 to get the AC going; However, if i'm altitude or it's really hot, after 20 minutes it overloads the 2000's surge capacity.
Hence i'm looking at a bigger unit . . .
Soft starts aside, to give you a clearer picture of your power needs, I'd suggest looking up the continuous current rating for your a/c unit. Or, better yet, use an AC clamp-on ammeter to verify the continuous current while it's operating.
A BTU rating only gives a very general idea of an a/c unit's power needs. Some of the more efficient 15k BTU a/c units can draw less continuous current than some 13.5k BTU a/c's. If the continuous current rating/reading is less than 13a, and a MAES is used/installed, most 2000w inverter generators (in good running condition) should power it. If it's less than 15a, the newer 2200w Honda generator should power it.
