Connect the wires from the controller to the solar panel.
How to keep a solar panel from overcharging a battery.
A solar charge controller is a component that helps manage the power that is going into the battery store from the solar panel.
I ve spent the winter designing a pwm solar charge controller which is now finished and working.
Even a small solar panel hooked directly to a fully charged battery can overcharge it.
As peter said you can overcharge a battery if you don t have a solar controller between the solar panel and the battery.
Match up the male and female connectors with the opposite ones coming away from the solar panel and snap the mc4 connectors into place.
It is around 14v at 40c.
It safeguards the deep cycle batteries from being overcharged during the day.
Once you ve attached the input wires to the charge connector you should have 2 loose wires each ending in an mc4 connector.
A cheap pwm controller will do this ok though they are less efficient for the charging process.
Here i m using it to charge a 12 volt car battery as quickly as possible without overcharging.
The solar power generated by the solar panel is received by the solar charge controller.
