2023-05-29
The solar controller is an automatic control device used in a solar power generation system to control the multi-channel solar battery 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, and is a microcomputer data acquisition and monitoring control system. It can not only quickly collect the current working status of the solar 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, providing an accurate and reliable solution for evaluating the rationality of the PV system design and the reliability of the quality of the system components. sufficient basis. In addition, the solar controller also has the function of serial communication data transmission, which can centrally manage and remotely control multiple solar system sub-stations.
By using the innovative maximum power tracking technology, the solar controller can ensure the maximum efficiency of the solar array all day and all day. It can increase the working efficiency of solar modules by 30%. Also included is a search function that searches for the absolute maximum power output point every 2 hours across the entire solar panel operating voltage range. Three-level IU curve charging control with temperature compensation can significantly prolong battery life.
Lower-cost solar panels used in grid-connected systems with open circuit voltages up to 95V can be used in independent 12V or 24V systems through solar controllers, which can greatly reduce the cost of the entire system.
The function of solar controller:
1. Power adjustment function.
2. Communication function, simple indication function, protocol communication function.
3. Perfect protection function, electrical protection, reverse connection, short circuit, overcurrent.
