Inverter/Battery/load combination
All, I just took delivery of a new Cardinal 5er. Came with residential Frigidaire Refrigerator, Label says 8.5amp draw The coach also was wired with a Xantrex 2000W ProWatt SW dedicated to power...

I think the best way to troubleshoot this is to try running the fridge on inverter at the house for several hours prior to taking a trip. This way you can watch things and see what is happening. I don't know about the Frigidaire but the Samsung RF18 has two compressors. The 8.5A draw on 110vac seems awfully high. You can roughly figure the DC amperage draw on the batteries as 10 times the AC current draw, so 8.5A AC would be around 85A DC on the batteries. I personally went with dual 12V batteries but yours should work. Experiment with it at the house and good luck.
