I’m not familiar with the Yami but as others has stated, refer and hot water heater need to be on LPG, fan set on LOW speed, and on board converter-charger set to off...Generator will loose a bit of efficiency (continuous output) once fully warmed-up (say beyond 30 min) and when at higher elevations, and air cond will draw a bit more current at the highest ambient temps...
FWIW, I just replaced my Honda 2000i with the new Honda 2200i and on our first outing out found that in out in the high desert at about 6,000’ with ambient at about 95df, it still won’t run my 11k btu Coleman Mach 1 P.S. while on Eco, but I found that where the former 2000i struggled and would often overload at this same location, the 2000i delivered continuously without a hitch....Camper interior temps dropped from 97df to 77df without any hiccups ...
Published running amps for the Coleman are 9.0a (compressor and fan), but actual measured running amps are closer to 9.5a for the compressor only and 2.1a for fan (coils are clean)...This is only our first test run, but in my view the extra 200w is what made the difference...It’s not quite clear to me that running the air cond on Eco is a viable option, at least at these higher elevations...JMO
