I wanted to figure out just how much power our Norcold 12 refrigerator uses in 24-36 hour period.

With our Alliance 340RL parked in our barn, so it is getting no solar power, I turned the Victron system off, so it was no longer charging the RV or creating AC power.

Of course refrigerators don’t run/cool 24hrs a day, so you will see times with just over 1.1 amps being drawn and other times with 6.9 amps being drawn. It was 85 degrees as a high in the barn and 55 degrees for the low overnight

I was a bit surprising to see the Norcold frig used over 113.4Ah in 25.5 hours…and then almost 163Ah after 36hrs. Test done on 810Ah of Lithium batteries from 4 year old Battle Born batteries

Of note...there are tiny vampire DC draws that I did not turn off…stuff like LED on radio, Co2 detector, etc
