    This is exactly what happened to us in June. I accidently hit the Battery disconnect and the following day our 12volt fridge had shut down. The fridge has a threshold of 11.6 volts. As soon as I figured out what had happened, and re-engaged the battery, all was well.

      Installed a 50 amp hookup on the side of my house. Plugged in the shore power. and left the battery disconnect alone. Fridge is working great. So if someone tells you to throw the disconnect when hooked to shore power. DONT.....

        New to the forum. Need advice.

        This is our first trailer. We just bought Grand Design 23LDE with a 12v 10 cft refrigerator, 165w solar panel and and 2 HD24 DP batteries. Trying to determine how long the batteries will run the refrigerator while boon docking. Ran a test yesterday. Plugged in and let the refrigerator get to operating temp and unplugged. It ran for about 11.5 hours in the sun and then shut off. It automatically shuts off at 10.5v. I have two small quiet generators but am curious if it will run all night without damaging the batteries.

        Any advice would be appreciated!

          There are so many variables that it's hard to give an answer. Here are some considerations:

          1. Is any shade hitting your panel?
          2. How hot is it? (The hotter it is, the more the refrigerator will run).
          3. What is the true capacity of your battery bank? For example, a typical group 24 RV lead acid battery will produce about 45 amp hours of power. Two will give you about 90 amp hours.
          4. What temperature to you try to maintain with the refrigertor?
          5. Were the batteries fully charged when you started the experiment?
          6. What other devices are the batteries running. Lights, furnace fans, stereos, ceiling fans, etc. all share the available power in the RV.

          I think you're on the right path with experimenting to see how your specific uses impact the length of time you can run. In my own application, I have 800 watts of solar and three 100 amp hour lithium batteries. I can run indefinitely as long as I get 5-6 hours of sunlight per day. If you find out that you're not able to run 24 hours without a recharge, there are two primary areas to focus. The first would be to increase your battery bank, and the second would be to add another panel to your roof.
