Residential Refrigerator

You will need an inverter with either 2 or 4 batteries depending on size. I run a 2800 watt pure sine inverter with 4 6v batteries. On smaller inverters you may have to switch between converter and inverter if you are on shore power or on the road. The larger inverters such as the one I have takes care of that automatically. If you want to just make sure your frig works while you are traveling you can go with a smaller say 1000 watt inverter and 2 12 volt batteries. If you want to boondocks, do solar etc. then you will need more. By the way the res. frigs are great.
