The solar charge controller provides automatic lighting control functions which is food for street and pathway lighting systems.
The advantage of BR Solar marked solar charge controller.
1. Automatic control technology based on MCU and special software.
2. Tandem PWM charge control method, so that the voltage loss of electrical circuit is only half of the diode charge, charge efficiency improved by 3% - 6%.
3. The over discharging recovery control and automatically floating charge control can increase battery service life.
4. Battery reverse connection protection, over-voltage protection and under-voltage protection.
5. Solar module reverse connection protection.
6. Automatically recovery output, output over current protection and out short circuit protection
7. Intelligent time control system
8. Light control, time control, temperature control
9. High-precision voltage control for the battery safety work.
10. Waterproof design.
