I live off the grid with a 4.3 KWH PV system and 8 Rolls Surrette 6v/400ah LA batteries. I have a full size Kenmore side by side fridge that I brought with me from my previous home in the suburbs. To make it more efficient I turned both the fridge and freezer down to the lowest setting-this is the warmest setting if you want to look at it that way. I turned off the ice maker and went back to using trays that I empty into the ice dispenser on the freezer door (a nice lux item!). I have (2) 1 gallon water cubes that I rotate (daily) frozen between the freezer and fridge. These take up the top shelves of both sides, but the extra coolness from the frozen cubes keeps running minimal. The fridge, lcd tv, and LED lights are all I run on electric for the most part. When the sun is out - I will run the washer during the late morning/early afternoon - I line dry, so no dryer appliance needed. My heat comes from a Sedore 3000, Hot water from a SunBank solar hot water heater, and I cook on a Brown non-electric LP stove (100lb LP tank). I never have an issue with low batteries, even on multi day rain events.
