The diagram below shows the working principle of the most basic solar charge and discharge controller. The system consists of a PV module, battery, controller circuit, and load. Switch 1 and Switch 2 are the charging switch and the discharging switch, respectively.
At the heart of this process is the solar charge controller’s ability to discern the battery’s current state of charge. It does this by measuring the voltage, which gives an indication of the battery’s overall charge level. Based on this information, the controller adjusts the power output from the solar panels.
This is called the charging system. As you’ll learn below, the solar battery charging process is also a controlled chain of events to prevent damage. The solar battery charging system is only complete if these components are in working order: the array or panels, the charge controller, and the batteries.
During daytime the panel starts to load power to the battery (charge or PV load) until full charge it automatically cut off. In the evening when switch on the power button it starts to load power to the lights ( battery load).
No, the terms "solar charge controller" and "solar charge regulator" are often used interchangeably and refer to the same device. Both terms describe the component of a solar panel system with the function of regulating the charging process to protect the batteries and ensure efficient operation.
The solar battery charging system is only complete if these components are in working order: the array or panels, the charge controller, and the batteries. Here is what happens right from when sunlight hits the panel to when the battery receives and stores energy:
