Charge Controller

The charge controller (charge regulator) monitors the battery's charge state and should have logic control to know when and how much to charge the batteries. It must also be able to change the charge voltage, depending on the temperature of the battery.The same logic circuit will also protect the battery from discharging, below its lowest acceptable voltage, to prevent damage by over discharge. The charge controller also protects against wrong connection of the battery and reverse voltage to the panel.
