Solar Charge Controller Unit

 Solar Charge Controller Unit is a device that controls the charging process of the battery, monitors the status of the battery also generates alarms when required. Before microcontrollers, analogue charge controllers were used. Nowadays microcontroller-based solar charge controllers are quite popular. The benefit of these CCUs is that we can use MPPT or PWM algorithms for controlling the charging process. These algorithms help to harness maximum power from the PV panel. Even nowadays displays can be interfaced to show the Battery Voltage, Current, and Load Parameters.

Maximum Power Point:
The maximum power point (MPP) represents the bias potential at which the solar cell outputs the maximum net power. The MPP voltage can drift depending on a wide range of variables including the irradiance intensity, device temperature, and device degradation [1].

Indicator function:


Dusk to Dawn Feature:
The dusk to Dawn (D2D) feature enables the CCU to automatically turn on the load during low-light situations. Dusk to Dawn Charge controller turns the light on during the evening and then turns it back off during dawn. This feature is widely used in Solar Powered Street Lights, as it saves electricity and manpower.
