I hate to say it but this is like feeding a 500 horsepower Kenworth with a 5 gallon container of fuel.
I have a 3,300 amp hour 24 volt bank of batteries for the Trace 4024 to chew on. This is the energy of SIX THOUSAND SIX HUNDRED ampere hours of 12 volt batteries.
If I should try to operate the single Coleman roof air, absolutely nothing else through the inverter, it is a 95 ampere continuous draw with a peak cold start of 130 amperes. Ten hours of operation, a lousy pitiful ten hours, extracts 950 ampere hours. Thirty hours of operation means 2,850 ampere hours. Guess what, I have severely over depleted that battery bank that weighs more than a one ton chevy diesel pickup truck.
Please help me to understand your rationale of choosing a 5,000 watt inverter.
