Solar charged second battery
Hi,
We are going though Africa in a Land Rover shortly, and are trying to set up a cheap, effective separate battery system to run various bits and pieces. Current thinking is per the attached wiring diagram (apols for it’s amateur, unconventional nature – complete beginners, clueless about electrics).
THE THEORY:
· A solar trickle charger permanently connected to the leisure battery keeps it continuously topped up (we will be in the sun continuously).
· A cigarette lighter socket is connect to the battery with crocodile clips, with a 30 amp inline fuse on the positive wire.
· A multiple socket lighter adapter for the cigarette lighter socket allow us to hook up various bits and pieces – in particular an inverter for running a laptop, and an electric coolerbox to provide a cold at the end of each day’s driving.
· Made from CHEAP components, and kept VERY basic.
QUESTIONS:
· Will this work / are there any glaring flaws / minor adjustments that would make it work?
· Is the size of the Solar Trickle Charger sufficient to keep this running pretty much ad infinitum?
· What type/thickness should the wire from the battery to the Cigarette Lighter Socket be?
Would appreciate any insight you could provide.
Many thanks
Brett
