Industrial-grade solar power system control panel electronic solution

The full name of the solar controller is the solar charge and discharge controller. It 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.



1. Function description


This product is a new generation of intelligent solar charge and discharge controller, adopts industrial-grade product reliability design, has super stability and extremely high service life
1. This series of example products automatically recognize the system voltage of 12V and 24V
2. This controller is used to protect the battery and avoid overcharging of the battery by the solar panel and over-discharging of the load
3. Using MCU control, two indicating charging and discharging, capacity status
4. With three-stage series PWM regulation charging mode of strong charge, balanced charge and floating charge
5. Automatic detection and tracking of outside and battery temperature, built-in temperature compensation function
6. With comprehensive electronic protection functions: overcharge and overdischarge, overload, short circuit, reverse connection, etc.
7. With TVS lightning protection, no jumper design, which can improve the reliability and durability of the system
8. Parameter settings have the function of power-off saving, that is, important data such as system mode and control parameters are saved in
9. The inside of the chip is not lost after power down, making the system work more reliable.
10. All controls use industrial-grade chips and precision components, which can operate normally in cold, high temperature, and humid environments
