We attempted to run the AC (Dometic 3300) in the new Winnebago with a Kipor 2600 generator. With the generator running, the AC “moaned” and the compressor refused to start. The fan in the AC unit worked.
Spoke with Dometic who advised that a 2kva generator with invertor technology should start the unit.
Spoke with Sydney RV and Michael advised that the Kipor WILL run the AC unit provided that you TURN OFF the electrical power to the water heater if it has been left on. The water heater draws .5kva power when running. After starting the AC unit, you can restart the water heater on electrical power or run it from gas.
Needless to say, the information from Michael was correct.
