We have a typical Dometic propane/AC fridge. Have been following this debate for a while; however, I have not seen a discussion of how many Watt-hours are required to run a compressor unit for a day.
We are able to run the Dometic on AC during days of good sunshine from the solar (1400 W) and from battery suite overnight (9.6 kW-hrs of LFP) in midsummer but we do wake up with a 3 to 4 kW-hr deficit. This is no problem in mid-summer since we can harvest over 8 kW-hours. However, we primarily boondock and some of our favorite sites have heavy foliage (it can also rain and be overcast for a week at a time), aka very little solar. Therefore, the propane makes sense for much of our travel.
