I have 6,500 gas generator to run two 12,500btu roof a/c units on my bus.Nothing but problem after problem with generator.I was advised to change unit out to diesel unit! Any advise on what size i should be looking for?
If you love the roar of a diesel engine and the smell of diesel fuel then I guess that's the way to go, places like Camping World have technicians that can answer all your questions and will also sell and install the perfect unit for you.
You don't say what the generator problems are. It may be undersized for the AC units you are trying to run plus other things you are trying to run. The AC unit may require all of the generator's capacity for about 2 seconds to start. So if one AC is running, there may not be enough capacity to start the second AC unit. What other things are you running off the generator at the same time? The 6,500 watt generator can only supply a maximum of 27 amps out of the 240 volt outlet or 15 amps out of each of the 120 volt outlets or any combination that does not exceed the 6,500 watt capacity of the generator. A diesel engine has nothing to do with the capacity of the generator. Diesel engines are used on larger capacity generators or continuous duty generator sets. The generator itself doesn't care what type of engine is spinning the rotor. Will the generator run just one of the units? If it does, then my thoughts are the generator doesn't have the capacity to run the loads you have.
