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.

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

Yes, what’s wrong with using propane?

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.

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.

Absorption refrigerators are energy hogs, running on an inverter will take a lot of power.

Why not run it on 12 volts if the fridge has a 12 volt setting? Inverting 12 volts DC to 120 AC takes power. Your batteries will last longer if you run the fridge on 12. If you only have gas or AC, I can understand why you want an inverter.

Any time we have full sun and im headed down the road on longer trips I use my fridge on AC off the inverter. I have 400W of solar plus the small trickle charge from the truck so I save a small amount of LP.

Thanks guys...so My last camper had a 3way fridge. Originally my dealer disconnected the dc operation in fear that I would kill my battery by forgetting to change it over to gas when I might go into a restaurant or whatever. I did have him reconnect it and I absolutely loved running it on dc while running down the road. I had absolutely no trouble at all and never killed my battery. I was vigilant about changing over to gas or electric when it was available. So fast forward. I do have no trouble running on gas down the road and it does function fully. Unfortunately my new fridge only runs a/c - propane. I noticed my fridge plug was so accessible, I figured I would ask here if it could be done before I ordered an inverter.
Thanks again for all the responses.

I don't understand why you wouldn't run it on propane
our fridge runs on propane for days at a time, perfectly I might add

running electrically while on the road so basically off the alternator is still going to cost something(vehicle fuel), the alternator is not a free energy source

with all the various losses, particularly at the invertor(heat), it will likely cost more to run it electrically not to mention more wear on the alternator and its drive system
