The MPPT controller has the function of maximizing charging power under different lighting conditions. Compared with the PWM controller, it can use solar energy more efficiently and adapt to a wider PV voltage range. It uses wireless communication and can be built on 4G and 5G networks. It has the advantages of low power consumption and wide coverage. Each street lamp uses a separate e-sim card for communication, and there will be no batch loss of connection. The specific product features are as follows:

1. Automatic period control: multiple period strategies can be set, and the duration and lighting power can be defined for each period. The controller automatically determines day and night based on the PV voltage;

2. Adaptive morning light: The controller automatically calculates the night duration based on the changes of day and night to ensure the correct execution of the morning light period;

3. Fine management: In the case of multiple lamp heads on one lamp pole, it can achieve precise control of a single lamp head and deeply realize on-demand lighting.

4. Platform management: Controllers with NB function can view the controller status, charging amount, discharging amount, alarm information and other operating data through the Internet of Things management platform, and can remotely modify the controller time period parameters through the platform to achieve remote operation and maintenance;

5. Automatic power reduction: After the battery voltage drops to the set power reduction point, the controller automatically lowers the load brightness, prolongs the lighting time, and ensures that the light does not go out during continuous rainy days;

6. MPPT charging: When charging, the controller automatically tracks the maximum output power point of PV and uses solar energy for charging with maximum efficiency;

7. Overheat protection: If the internal temperature is detected to be too high during charging or discharging, the controller will work at a reduced rate to avoid overheating damage;

8. Power-on test light: After correctly connecting PV and light source, connecting the battery will trigger the power-on test light, the light source will light up, and the light source will go out after 20 seconds, and the test light ends;

9. External temperature sensing: You can install an external temperature sensor to detect the external temperature to achieve external temperature protection (special customized function);

10. Human body sensing: The controller can be connected to an external microwave (or infrared) sensor to achieve induction lighting (special customized function).
