Residential Fridges

I see a few posts about residential fridges
obviously running one in a campground is not an issue, but can you run one on the road or boondocking and for how long typically?
I assume an inverter of adequate size is required(or generator) for road/boondocking use plus adequate battery power

  • I did a limited test, in the drive way.
    Fridge is an Samsung RF18.
    Inverter is a Tripplite RV750ULHW.
    Batteries are 5-year-old T105 flooded cell. MH is on 30amp/110v all the time, at the house. Water level above plates.
    All measurements were done at the battery terminals. Starting, I flipped the CB off and the bats were at 12.6. At 8 hours the bats were at 12.1 and I turned 110 back on.

  • Mine setup with solar works well boondocking. Cloudy days, the generator may come into play.

    The inverter can be a smaller (1000W ish) inverter just for the fridge but most have a whole house inverter (2000W or higher) that also powers the fridge. Having the larger inverter is good if you also have a larger battery bank as the larger inverters will have a much better battery charger to top off the batteries quicker if you do need to run the generator.

    X2 Most big rigs need 2-3 hours of generator time even without a residential refrigerator. I added a 2nd system (batteries, 1000W PSW inverter, and 100A charger) for my 21 cuft refer install. 2 batteries will power it for 30 hours before needing to recharge...longer than the house batteries. Best mod ever.
