DC to AC INVERTOR - FANLESS

I installed an invertor under the bed in our RV in order to be able to run my CPAP machine while dry camping. The invertor is well oversized (4000W) and runs the CPAP very well.

Problem is the unit has a very annoying fan that starts and stops frequently (even if the CPAP is not plugged in or in use). I picked up the unit at Harbor Freight and it may not be of the highest quality.

I'd like to replace the inverter with one that doesn't require a cooling fan. Without the humidifier (which is how I use the CPAP when dry camping) the load is only 1.09 amps at 120 Watts. However, I'm not able to find this kind of unit that isn't just the kind that you plug into your cigarette socket. The current unit is wired on the supply side and has a normal 110V outlet on the output side.

Any suggestions on how to address the fan issue?

Thanks

I have not seen an inverter without a cooling fan except for those small charge your cell phone types.
I installed a 1000 watt Zantrex inverter in the battery compartment of our camper and ran a wire back to the kitchen area....... (to make blender beverages in the woods!)

You could mount yours remotely and you should also have a switch on the 12 volt side to turn it off when not in use.
It still draws power when no load is connected.

If you wanted to spend a bit more money on your inverter the Zantrex can be mounted remotely and has a small control panel you connect with a network cable and can operate it and read voltage and current draw remotely.
