Update:
Thanks to All !!....So at 90df in my garage I took the cover off the rooftop Coleman and using a clamp-on meter at the compressor (excluding fan), I came up with this having no other appliances on...
On shore power:
Shore power volts, no load 117v
Shore power volts w/compressor running 113v
Volts at compressor 111 to 112v
Amps at comp motor (minus fan) 9.2a
On Honda 2200i:
Volts at Generator, no load 127v
Volts at Generator, w/compressor running 124v
Volts at compressor 120v
Amps at compressor (minus fan) 9.4 to 9.5a
The results seem a bit ambiguous, but it appears that the compressor amps are high - If I can believe Colemans specs of 9.0 total amps (incl. fan) at 95df (90df during my test), and the fan is supposedly using about 2.5a, then the actual compressor only amps should be about 6.5a, which (if correct) means that the compressor is using 2.5-3.0 extra amps than the specs call for. Seems like quite an overage to me, yet the air runs fine otherwise - maybe a bad omen awaits - lol
The air unit is about 9.5 yrs old, but has not been used a whole lot...I have run it off the inverter only occasionally (for brief times), but the inverter seems to have no problem starting or running it, shore power always works too - Operationally, it’s only the genny that struggles (only when on Eco...), except when the inverter is set to ‘standby mode’ to assist with compressor starts...And this charicteristic is when at higher ambient temps and elevations (4,800’), so it’s not clear to me that it’s all that unusual (I just don’t know....??)....Absent other issues causes me to ponder the ‘outside-chance’ as to whether Coleman’s published spec’s for this particular unit are quite accurate or possibly outdated...Maybe just ‘wishful thinking’ here, admittedly, I have no other experience with a Coleman air conditioner...
