First, I plan to follow the weather and not be camping in 100 degree sun or freezing temps. Second, I have a residential refrigerator behind me in this house and for the last 15 or 30 minutes it has been quiet. The point is, they don't run 24/7. And if you don't open the door a lot it can hold it's cold temps for several hours offline. The other day they shut off power here (in Colombia) for 8 hours and our food in the fridge stayed pretty close to normal temps.
My thought is to also supplement with some solar and run the generator when necessary. If I decide to boondock more often and longer then I may replace the original 2 12V batteries with 2 golf cart batteries, or whatever the best tech is. Maybe add more solar or nuclear. HA HA. Sound like a plan?
No it does not sound like a good plan. First the 100 watt/10 amp estimate was for use in moderate temps with cycling on and off. Again a battery will last about 3 1/2 hours in those conditions. If the temperatures go up to 80 degrees, or if you add some warm beverages or food, the units will consume more power. If you shut it off for a while, then it will run continuously for hours to make up the loss.
If you are going to boondock you will need to have a serious solar system with sun, of course, or you will need to run a generator for hours and hours and frequently. You will also need a serious bank of batteries to carry you over the night time or when the sun it not shining or when you are not allowed to run a generator. There are lots of reasons for propane refrigerators.
There is another choice. You can get a highly efficient 12 volt compressor refrigerator. Most of them are small and expensive. I have one. It is about the size of a small dorm refrigerator and cost well over $1000 several years ago. I also have a solar system and another $1000 of AGM batteries.
