Solar Supplement Recommendations

I had a new Norcold Refridgerator (2 way) installed which works great. The RV is parked most of the month and I live in the Clearwater Florida area. I have really good quality shore batteries and mostly use the RV at an RV campground in the area when I am home.

The Norcold model NA7LX draws .93 amps and 11 watts when on LP mode. So when I come in even though the shore batteries are in ok shape the Refridge starts to indicate a low voltage condition after a short while.

My question is would a basic solar panel system produce enough juice to provide adequate amps and watts to power the Refrigerator on LP mode? I called Norcold and they said the chance was 50/50 of it working. It seems like such a low requirement to provide enough electricity from a 100 watt solar system but maybe I'm thinking wrong.... Thanks.

  • What are you running for house batteries?

    A single 100 watt panel should be enough, IF you have good sun every day, a couple of very cloudy or rainy days would take away most of the recharging. A single group 27 Battery would make the rainy days a problem quickly, 4 GC-2 Batteries with 100 watts of solar would likely do fine because you would have sufficient reserve power to carry you through those rainy days.
