Hi
What interior do you have?
Also what do you want to run off it? Do you want to take a feed up to the fusebox and run your interior lights and stereo or just have a separate outlet that you can then use to run stuff?
Have a search on here for leisure battery setup - I had a thread going with various diagrams to show how I set mine up
There are a few options to be fair ranging from:
A simple setup with a battery in the boot and a wire coming out to a separate outlet/fusebox and then outlets
add into this:
ability to charge the leisure battery when you go along?
- you then need a split charge relay to simply charge the battery when the van runs
- or a split charge module that detects when voltage is above 13v and then switches charge to the battery
- or a split charge board/module that does the above but then allows you to take a feed to particular appliances like a fridge, that runs of leisure battery when parked, but main battery whilst running
ability to charge the leisure battery when you plug into a power socket?
- you'll need a 240v socket on the van - if you have a westy you can use the yellow US plugs (think aogrady sells them on here)
- you'll then need a 240v fuse board that you can connect to a socket for 240v power
- you'll then need a battery charger than runs on 240v off the fuse board, then connects to the battery to charge the leisure battery when the van is plugged into 240v
do you want 240v when not plugged into the shoreline power?
- you'll need an invertor plugged into the leisure battery then a 240v socket connected somewhere (most invertors have one built in but nicer to run to a permanent socket
Would you prefer to have an easy option (though more expensive)?
- then google for Zig units that have all the required logic and switches built in - you connect to the battery, the 240v input and to the leisure battery and they sort it all out
It's cheaper, easier to fix and more flexible to go for the component layout with separate 240v fuse box, invertor and 12v charger - takes up more room, Zig type units are a cleaner/smaller install - but cost more
Hope the above is helpful?
