Wiring refrigerator to batteries

Yes it will be run on LP as well. Just needs the DC to light because it has an LED screen (is how I was explained the situation).

Presumably you understand that installing a gas absorption fridge has specific requirements that a conventional compressor fridge does not - details are in that installation manual linked to earlier.

The LED screen is beside the point - the N641 is a DSI fridge so it needs 12 vdc to run the main circuit board, spark the ignitor, and operate the gas solenoid ... without 12 vdc it's just not going to work at all, even when forced to the gas mode.

I guess my husband just didn't get as technical with me. My question was how to hook it up to the battery so that it will run with battery power and propane. I don't know where you are getting the idea we are trying to get away from using 12 volt, but anyway I got the answer we needed with the links to the manual. We have had trailers for many years, just have not installed a new refrigerator or have had to depend on total solar/12 volt power.

Unfortunately, properly installing any gas absorption fridge is quite technical and is not as simple as sliding a compressor fridge into position and plugging it in. The fact you've come here to the forums to ask such a simple question about how to feed it 12 vdc because the fridge "needs the DC to light because it has an LED screen" raises alarm bells as to whether you understand just how important it is to install such a fridge properly so it not only functions as intended but also doesn't subsequently kill you by venting CO inside the camper, either / both of which can easily occur if you don't understand & follow those installation instructions which are clearly detailed in the aforementioned installation manual that is available to anyone to download ... including yourself. :R

Good luck with this project - sounds like you're gonna need it. :)
