Alex, although I have not installed this particular
refrigerator, I have installed a NOVAKOOL Danfos 12 volt only
refrigerator in our 13'
Scamp, using a single 100 watt Renogy
solar panel hooked to a single group 27
battery, with great results.
I have also installed a 12 volt only Truckfridge (I think that this may be a rebadged Engel) Danfos
refrigerator, using a single 160 watt Renogy
solar panel and a group D AGM
battery. I don't think I will ever go back to using an absorption style refrigerator again. I do have a 2000 watt Yamaha
generator incase of several rainey days, or shadey campsites. I have been looking into wind generators for RVs just for fun, but I don't think I would go that route. Just as a side note, the people at NOVAKOOL encourages extra insulation around the refrigerator where ever possible, and I had used a combination of ridged styrofoam and reflectix.
Best of luck with your project.
