12volt conversion/addition

[Lorraine_374412928]

I am trying to run both a 240v and 12v system in my German Caravan. At the moment I have a 12V transformer for running a few 12V devices but have to rely on an external 240v source.

I am thinking of purchasing a 12V battery for the caravan so I can run these devices when I don't have any 240V and then charging the battery when I'm not using it. I have thought of a few ways of doing this however am looking for some advice.

My first thought was to have a manual switching system where I can switch between the 12V transformer and the 12V battery. E.g. When i'm at a site with 240V electricity I can just run the transformer. When there is no 240V I can switch to the battery source. My second thought was to see if I can get a device to do this automatically.

If anyone has any comments or any suggestions how I can go about doing this please feel free to respond

Follow the links to the pictures and explanations,and read all the information.

It is a relatively easy thing to do if you have 12v experience or know someone who does and can help you.
