Solar controllers are used to manage the voltage and current created by the Photovoltaic module. A 12 volt module can product between 0-22 volts so the controller is used to regulate battery charging and turn off charging if the voltage isn't high enough to charge the batteries.

An MPPT featured controller can be used to optimise charging performance on low light days or during cold weather. These features are normally available on the higher spec units but you can purchase a module seperately to retro fit a system.
