I have a dorm size residential fridge that I put a watt meter on and tested for several days. It averaged .85 kwh per day, 90-110 watt running, 1.2 amp draw running on 110v. If my math is right that is 12.14 amp dc when running. Assuming it has a 50% duty cycle per hour it would give about 20-22 hrs of use with 2 6v GC batteries discharged to 50%. With out additional batteries that would require either a generator or solar for charging every day. Assuming there is no 110v hook-up available. My calculations were figured in a vacuum with no allowances for inverter loss, line drop, heat or battery condition.
