4.3 - Solar charge controller
See figure 5 for the circuit layout. Wiring of batteries and ground
are pre-wired. Connect cable 1 and 2 as in figure 5 and see par.
4.4 for the technical specification.
Make sure battery and solar panel are disconnected to controller,
and do not connect the positive and negative terminals of solar
