CC mounted the inverter/charger on my Allure in the rear most passenger side compartment. The small enclosure for much of the 12V stuff and the inverter is poorly ventilated and is very close to the engine bay and just over the muffler. The original Xantrex inverter failed on the prior owner and the Magnum Energy inverter he used to replace the Xantrex failed on me. The Magnum kept overheating. I monitor the temps in that space and they were exceeding 120F many times.
When I had the Magnum replaced with a new Magnum, I had the shop cut a hole in the partition between the inverter area and the battery compartment. They installed a new muffin fan in that hole. So the original fan that CC installed pulls air in from the lower front and the new fan exhausts hot air from the top rear into the battery compartment. Better but it still gets very hot in that area, especially in warmer weather.
So, I decided to install a waterproof high flow fan in the battery compartment door to help move the hot air to outside. I had misgivings about drilling a 4 1/4" hole in the door but I am pleased with the end result.
I was impressed with how thick the aluminum was on the outside of the door. I inserted some tubing into the gap between the inner and outer panels to fill the space. I used RTV to seal it well to prevent water that may splash into the vent from collecting inside the door between the panels.
This is the fan mounted on the inside of the door. It is attached to the same temp control that turns on the other two fans.
Finally, this is the polished stainless louver I installed over the opening.
This fan really moves a lot of air. I will test my work on the next trip and see if the temps drop even more.
I realize CC was motivated to locate the inverter near the batteries but it certainly would have made more sense to do something different/better.
