This may be helpful to some. I spent some time weeks ago looking for some data as to what the draw is with the fridge in our camper and didn't find much. So now that I've got it ready for camping I spent a few days running the fridge on solar only with a Renogy 100AH lithium battery that has built in Bluetooth.
My curiosity was how many days with sun, of course, could I realistically stay out on a single 100AH battery if we were extremely careful with other DC components. Lights could be supplemented with AA type and the other main draw is the water pump.
I started at 10am on a sunny day, outside temperatures are around 80 here, with the fridge off and 100% battery. Where it sits, it only gets about 6 hours of full sun.
This fridge has an area on the dial for off-grid, which I found only got down to about 44°. So I ended up with the temperature dial at 12 o clock which is in the center and it got to 38°. It only took about 2 hours to cool to temp. I was trying to get below 40° for safe food storage.
Through the day there was no battery loss. At 8pm it was at 92% and 12 hours later at 8am it was at 72%.
The following day was cool and rainy, there was an hour or two of partial sun during the afternoon hours. At 7pm, 33 hours after turning on the fridge, the battery was at 84%.
On to the following morning, at 7am battery had dropped to 70%. That day was bright sunshine all day and mid 80's for outside temperatures. At 7pm, battery was at 96%, 57 hours after turning on fridge. This was the end of my test.
While nowhere close to scientific, it seemed like during the hottest part of the day the fridge cycles were about 50minutes. 30 minutes off and compressor running for about 20 minutes. The highest amp draw I recorded during the night time was about 6.2amps and on average was 5.6amps.
