Inverter Use

Hi All, Has anyone tried running their RV fridge on a basic inverter.
In my case I have easy access to the plug on my fridge. I would disconnect the plug from the 110v outlet and plug it into an inverter. What size inverter would I need for a 3.7 size Norcold Fridge. I was thinking at least a 750W.

  • Absorption refrigerators are energy hogs, running on an inverter will take a lot of power.
  • Do you want to use AC while driving for some reason? IF so then provided your Tacoma alternator is adequate for the job then install the inverter in the truck and run AC wiring to the RV. Adequate as per above it will be about an extra 30A draw.
  • Yes I have used my 300w GoPower inverter to power the Dometic absorption fridge. Pulls almost 30 amps from the 12v battery when the cooling unit is cycled on. Most batteries will be dead in a couple hours. Probably 400 to 600 watts is actually plenty as I believe the heating elements are about 325 watts.

    I used mine when leaving town and the propane burner would not light. No time so used the inverter until I was at location and was able to get the propane going again. Turned out to be a loose connection to the propane valve solenoid.

    The question is why go to that trouble when you can run it on gas?
