We have residential fridge with inverter and 4 GC2 batteries. I start fridge cooling when I pick up at storage. Plug into 110v when I get to the house. Freezer at -2°and Fridge at 38° in two hours or less. Alternator keeps batteries up while driving. When boondocking I use a combination of solar (portable 240w) and Generator. I run generator until I hit float, so longer in the morning (2.5 hours) than afternoon when solar has helped. We leave an LED Lamp on in the living room all night, watch TV and support all the other parasitic loads.
We have the Samsung RF18 and a Magnum 2000w pure sine inverter/converter. Setting converter to max charge current reduces generator run time. When I first fire it up in the morning, it puts about 100 amps back into the batteries during the bulk phase of charging.
We love having so much room, and rarely fill the fridge to capacity. We make ice while driving or on shore power. Ice Maker is turned off when boondocking.
