Where are folks buying the Vitrifrigo DP-150 12 V/120 V? All I can find is outlets in Australia using google.

My experience running refrigerator on 12v

My Dometic refrigerator draws about 3 amps on 120v and 33 amps on 12 (measured with a Trimetic meter) when run with a 450 watt modified sine wave inverter.

Based on that, if you have a single group 24 battery with about 75 amp hours, you could run your refrigerator about 1/2 hour before risking damage to your battery.

In my case, I have 300 amp hours of batteries plus 400 watts of solar and I can run my refrigerator with the inverter while driving for 5 or 6 hours and have from 0% to 8% battery drain depending on sun, clouds etc...

"Where are folks buying the Vitrifrigo [refrigerators]?"

Sure Marine Service. They sell Vitrifrigo, Isotherm, and Novakool 12 V compressor refrigerators in a variety of shapes and sizes. (And Force 10 all-stainless marine stoves--my new Airstream will be getting one of those as well! :-)

I purchased the DP2600 model and I believe that I bought it from Bay Marine in San Diego....

My propane usage is greatly reduced, there's no worry about fire, and no need to shut off the fridge at gas stations... I love it! Electric power consumption is typically about one sixth that of a standard RV absorption fridge operated from an inverter. The only drawback is the cost--these compressor fridges are about 40% more expensive than standard RV fridges. Well worth it to me, though!
Hello there,

We just purchased 72 Tradewind 2 weeks ago and we were wondering what exactly do we need to run only electrical fridge as you mentioned? If we install 2 or 3 batteries in our trailer and solar panels.. would it be enough to support the fridge? Thank you. Aras.

Depends on the refer size and solar panel capacity.
You will also need an inverter with ample capacity to start the compressor in the refer. It should be a pure some wave inverter.
Inverters of the size required to start a refer will require heavy duty wiring and ample protection (fuse) between the inverter and the battery(s).

For the Vitrifrigo, you don't need an inverter at all. When running, the Danfoss compressor pulls about 6 amps of 12vdc as I recall. The duty cycle averages about 50% in a reasonable climate so figure 72 amp/hours in a 24 hour day. Tough on a single battery, better with two, perfect with solar.

All you need with a Vitrifrigo is a bucket full of money.

True that. But I am still going that way when my Dometic finally gives it up.

I replaced the Dometic with the Vitrifrigo last Fall and have been extremely happy.

Have you priced a new Dometic lately? They're not bargains either... the Danfoss fridges are in the same ballpark price-wise with propane models.

Sorry as I do not know the electrical system terminologies yet.
I am planning to buy 2 Interstate Deep Cycle Group 27 batteries + Solar Panel (don't know which one yet). Do you think so that will be enough? Some says I need inverter some says no.. not sure how to proceed here.

Thanks a lot
Aras

If you plan to use a mini refer you will need an inverter unless you are going to be plugged in to shore power.
If you go with the "V" refer no inverter necessary. It runs on 12 volts.
