Good luck with a solution.

The fan is controlled by heat and current sensors to dissipate the heat created by charging and inverting. The higher the amperage load the more it will have to run. Make certain the battery bank in is good condition (bad or weak batteries will be contributing factor).

Welcome to the forum!
Are you certain that it is the inverter ( 120 AC output ) and not the converter ( 12-15 Volt DC output ) ?

as others have said, the fan (either inverter or converter) operates based upon need. Usually with little power draw the fan will not operate. In my motorhome, the fan on the converter seldom runs with several lights and charging, where the fan on the inverter will readily come on with moderate loads. I also have a TT on a permanent space, it's converter fan will readily come on if I have several lights turned on.

If loads are minimal and the fan runs continually, is the unit running hot for some reason? Ensure there is no air blockage to the unit? Are the fans or a screen providing air clean? If more than one fan, are all working?

Make certain of the amperes going to the battery bank. This and air temperature around the inverter, will give you an indication as to the need for the inverter fan being needed. You may want to use some compressed air and blow out the venting of the inverter. The fan is controlled by a thermistor and would have to be sent in for repairs if all else is normal. I have only found a couple inverters with this being the only issue in 20+ years of service.

Hi rvdream,
My very limited experience indicates that the better quality/more expensive inverters use the fan "intelligently" (only when needed for cooling). The cheap inverters that I've used run the fan at max speed all the time which is very annoying. Not sure what you have but I'd follow the suggestion of measuring the current. If the inverter is basically "idle" but still blasting away with the fan, you might have a not-so-smart version. Sorry...
