residential refrigerator

In my 2007 Discovery we decided we would replace the Norcold 4000 series with a 18 CF Samsung. It is now in and it took less than 2 hours to obtain the desired temp. When running it pulls 16 amps of 12v power off the inverter. Hopefully my 4 Golf cart batteries will do the job as we don't boondock that often. I lucked out for power as when I removed the Norcold there were 2 110V outlets. With my multi-meter I discovered one of them was already wired to my inverter. By the way I installed a 2812 Magnum pure sine inverter. Anyone who has more questions about the installation feel free to ask.

    While the draw will be high for awhile while it first cools down things will greatly improve once it's cold. It won't draw that much continuously but only as needed once it is fully cooled down. I have an older larger fridge and it draws 3 A/C amps (30 DC via inverter) so it sounds like yours is much more efficient and you should do just fine with occasional dry camping. The generator could use a couple of hours exercise every now and then anyway!
