Lynn,
I have Sundanzer DDR165 directly connected to a 275 W panel with no battery. I would not like to live here without it. During 6 month long summer I need to drink at least 5 liters of cold home made beverages per day. My well water is a little bit too warm to cool my body from the inside.
I purchased it in 2014. For last 5 years I kept it outside in the elements. Works wonderfully.
Negatives:
1. Top loaded fridge is always dirty, it gets filthy in one week, because everything drops to it, liquids leaks out, butter falls, etc. For someone who would like to make some civilized cakes, tiramisu, cheesecakes, that need refrigeration would not be happy.
2. The seal has broke off and Sundanzer does not offer replacement parts any more for this model; they told me I would have to replace entire lid - what a waste! I tore off the glued seal and bought some adhesive universal white and wide seal. Just replaced it a week ago. They use the body of Electrolux fridges, but it was impossible for me to find the model number and SKU of the parts.
Also the side plastic compressor compartment cover got broken (when we played soccer) and there is no replacement either. I will have to fabricate it.
Of course in winter when it's overcast here, the fridge does not work too much with no battery backup and mold quickly develops inside.
I consider it to be my favorite tool.
I also have the same size freezer that I still need to connect to a panel and battery.
