I think I've finally cured my problem with the inverter/charger on my P42 overheating when the genset is running and simultaneously charging and running the A/C units. I epoxied a circular 4 in. exhaust hose flange to the rear of the inverter over the opening for the internal cooling fan. I then attached and routed a drier exhaust hose (foil type) around to a flange mounted to the edge of the shelf facing the door to the rear stateroom. I cut a round hole in the wood of the door and added a louvered vent to the outside. I removed just enough of the insulation to allow the flange on the shelf to fit snuggly. The inverter now draws air from the stateroom rather than the hot engine compartment. The exhaust from the inverter is still routed into the engine compartment. The additional noise when sleeping is negligible. I've tried it twice now and have no high temp shutdowns.
