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the ‘outside-chance’ as to whether Coleman’s published spec’s for this particular unit are quite accurate or possibly outdated...Maybe just ‘wishful thinking’ here, admittedly, I have no other experience with a Coleman air conditioner...
