AC/DC Compressor Refrigerators
I was looking at a motorhome that was equipped with an all-electric compressor refrigerator. I have never seen one before in a motorhome. I found a video on the net about the pros and cons of comp...

The amps in the posted link are rather limited and inconsistent. What is needed for a RV that is off grid is the power usage as in Ah or KWh. ie 0.9A AC for how long or say average KWh per day or year. That information is available for popular residential refers.
The AC power is 108W, 12V is 42W and 24V is 53W. This suggests that the AC power is rather inefficient, but when plugged in most would not care.
42W is reasonable but for how many hours a day is the critical missing information?
This unit may be efficient and a viable option for it's size but the information to determine this is lacking.
With 220Ah batteries at 12V the refer would run for 31 hours before reaching 50% SOC. If the cycle time is 25% then it's good for 5+ days. ie For fully charged batteries and no other loads.

Amps: 0.9 at 120V AC; 3.5 @ 12V DC; 2.2 @ 24V DC.
