I am doing a conversion and have installed a mach 8 as well. Was hoping ro run it via a 2800 watt magnum pure sine inverter powered by a combination of the high output alternater/transit batteries (engine idling) powering a 120 amp sterling batt to batt charger and 3 or 4 grp 31 AGMs (3-400 AH AGM).Yes. While driving. I haven't tested yet but (I don't trust my battery meter) according to my meter the AC unit draws around 80-90 amps from the batteries but alternator charge shows as 30 amps.Keep up how, like instantaneously while driving?
I’m curious why you went with 9,200 BTU/hr A/C when the 11,000 Power Saver requires less current. Coleman really needs to manufacture a Power Saver versión of 9,200 BTU/hr air conditioner. At 2/3 the size of a 13,500 Power Saver, they could get power requirement for a 9,000 BTU/hr A/C down to 700 ~750 Watts. I’d jump on that if it were available.
How have you connected your transit power to your house power and do you have the high output alternator/dual starting batts?
The 30A from the transit seems way low. If that is all I will get my scheme wont work.... I am counting on upwards of 100 A from the transit.
FWIW, I measured the mach 8 pulling 11.4A AC on high (10.7 on low) while plugged into an extension cord. Converting to DC A going into the inverter by multiplying by 11 yeilds 125A DC expected on high cool (118Avon low cool). Not the 90A you reported.
