The solar charge controller is called a solar charge and discharge controller, which is used in the solar power system, and then controls the automatic control of the battery charge and the load of the battery to the solar inverter.
The solar controller adopts high-speed CPU microprocessor and high precision A/D analog to digital converter. It is a microcomputer data acquisition and monitoring control system. The current working state of the photovoltaic system can be collected quickly and real-time, the work information of the PV station can be obtained at any time, and the historical data of the PV station can be accumulated in detail. It provides a very accurate basis for evaluating the rationality of the design of the PV system and testing the quality reliability of the components of the system. In addition, the solar charge controller also has a special function of serial communication data transmission, which can centrally manage and control the sub stations of multiple or many photovoltaic systems.
The controller with low power consumption should be selected. The controller works uninterruptedly for 24 hours. If the power consumption is larger, the power consumption will be consumed. The best choice is to choose the controller less than 10 mA.
If you choose MPPT solar charge controller with high charging efficiency, the controller with MCT charging mode can automatically track the maximum current of the battery, especially in the period of winter or light, and the MCT charging mode is about 20% higher than PWM solar charge controller.
