12 volt fridges use about 25 amps in a 24 hour period when set to 40 degrees. I measured this on my edgestar fp430 with a dc wattmeter, most 12 volt fridges use the danfoss compressor so they will have similar power use.
A 100 ah battery will only last you 2 days before you have to charge it, the reason is because you dont want to drain below 50 percent which will decrease the life of the battery.
From my own experience using a 75 ah agm battery, it wouldnt run the fridge more than a day without it being charged. Connected to my 120 watt panel and good weather, I could run the fridge 24/7 for months at a time.
Interesting, I didn't know the limit was 50%. I'm assuming that's the same with devices such as the Goal Zero Yeti etc? Good to hear about your panel. Do you have it permanently mounted on the roof? I'd love to do that but I have a CVT rooftop tent on there right now and thus no room to really put one.
