Residential Fridge Practicality

We have a Maytag 20 cubic ft. residential fridge in our Suites. We also have 4 6 volt batteries and a 2800 watt pure sine inverter. The inverter switches automatically between shore and battery power with no need to throw a switch. Someday we may add solar panels. As far as the fridge working no issue. The fridge is just like in a house. You have more storage and we have a built in ice maker and cold water dispenser. I have been told by others with a similar set up that 3 days on batteries is pretty much the norm. If needed the batteries can be recharged with the gen set 6500K if no shore or truck power available. The new fridges use very little power. If you want to boondock for a week or two you might want the rv fridge. However with solar panels the residential fridge will work also. You just need batteries to store the power. Good luck
