Re: 12v 5w LED light Solar/Battery source ?

Apostle40 to get a better idea of how 12 V systems are put together find a book on RV or boat wiring. These books will give you the basics of DC circuits for power and light. Many of the better books also include the formula for calculating the wire sizes needed for longer wire runs as well as the kind of wire cinstruction and insulation. Like everything else technical ther are many factors involved in putting together a safe, reliable system. i know of one person who killed himself when he short circuited a 12V line and the toxic fumes overcame him before he could take 4 steps to the open door.

The problem, he bought cheap wire at a discount store and failed to install proper fusing to protect the wire in case of an accidental short circuit.

Ther are books on Off-grid but they are fewer so chances are better in finding RV or boat books dealing with 12V wiring and the subject is essentially the same when it comes to basics.
