Wiring Diagrams - Off Grid Solar & Wind Power
Here we aim to provide a range
of typical wiring diagrams for solar & wind power systems, as well
as for battery bank wiring.
We often see batteries
incorrectly wired - especially when there are more than two 12v
batteries in parallel. Here's how we recommend that two or more 12v
batteries are wired to 12v or 24v. The idea is to make every battery do
the same amount of work and receive the same amount of charge.

Wiring multiple 12v batteries to 24v (PDF).
Cable size is important -
especially in solar & wind energy systems .... as a few percent of
energy lost in the cables can cost many hundreds of pounds to generate.

application, use our online cable
size calculator.
