What is a solar controller?

The full name of the solar controller is the solar charge and discharge controller, which is an automatic control device used in the solar power generation system to control the multi-channel solar cell array to charge the battery and the battery to supply power to the solar inverter load.

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. It can not only quickly collect the current working status of the photovoltaic system in real time, obtain the working information of the PV station at any time, but also accumulate the historical data of the PV station in detail. sufficient basis. In addition, the solar controller also has the function of serial communication data transmission, which can perform centralized management and remote control of multiple photovoltaic system substations.

The solar controller adopts microcomputer program control to realize intelligent optimization of SOC control, intelligent PWM charging mode, higher charging efficiency, and protection from overcharge, overdischarge, lightning protection, backflow prevention, and overheating. LED digital tube display, with power indicator and light control indicator. 12V/24V battery is automatically recognized without manual switching. Quality assurance, using SMT patch production technology, high-quality PCB, industrial-grade chips, can run stably in high temperature, high cold and other environments. With power display and light control designated time function, the battery power status is more direct, and the light control timing function is more practical.
