Not a very practical test but this
Video shows the refrigerator running on 1 battery for 40 hours. The test is conducted by putting a 24 bottle case of water in the refrigerator with nothing in the freezer. The door is never opened or closed during the entire test. I haven't been able to find any information regarding the power consumption in Watts or amps. There will probably need to be at least two batteries and probably more solar in order to keep the batteries up and run the refrigerator with other 12 volt demands.
