Tom,
If your unit has the Danfoss BD35/BD50 compressor, yes, the compressor motor is a 12V device. My Vitrifrigo has a Danfoss compressor with a power supply that accepts 12VDC, 24VDC and 110VAC inputs. When AC is available, the power supply defaults to 110VAC operation. In your case, if only 12VDC is available, the unit should run.
After a couple of years in service, my power supply went TU, and I had to replace it. The power supply unit is made by Danfoss, so the refrigerator brand doesn't matter. The part number of my power supply is 101N0500; Danfoss calls it an "electronic control unit." If you google that number, you'll get lots of hits.
Replacement is easy DIY. The unit comes off with one screw. Then, there is a single 3-wire power connection plug for the compressor side, and a bunch of slip-on connectors for the various incoming power connections, fan, interior light and thermostat controls. I found an Internet price at $272 from gsistore.com http://gsistore.com/. All others were much higher, but that was a year ago, so check around. The cost does create some heart burn, so DIY definitely makes sense, as it will save you a professional service call on top of the price of the part. Take a picture of your electrical connections before you un-install anything. Make sure you count the male spade connectors on the power supply correctly; they can be hard to see in cramped quarters. There is nothing technically challenging about replacing the power supply, but small hands would be an advantage.
Hope this helps.
