Once the refrigerator is cold, it will require a minimal amount of wattage to keep it running. Do some research on your particular fridge, and determine the watt draw on 120 start-up is. I suspect “near zero”, as the fridge does not have a compressor as a house refrigerator! We have a little 800 watt inverter (seperate from the big 2500 watt inverter) dedicated to our little 5cu. ft. chest freezer (it does have a compressor) and the bedroom television. I think I would go a little bigger than the 300, a little “overkill” (hunting talk) can’t hurt! memtb
