400W Wind/PV Hybrid Street Light Controller(Buck)
Performance:
1. Design for off-grid wind/solar hybrid street light system.
2. Integrated design of wind controller and solar controller.
3. Applicable to different kinds of batteries .
4. PWM stepless unload mode, which burn the excess power into mosfet, making the battery charging in best status.
5. Digital intelligent control, With powerful imported MCU control as the core device .To ensure Simple peripheral circuit structure, And more flexible and powerful control method and control strategy.
6. Modular design with simple structure and easy maintenance.
7. LCD display function, visually display wind power , wind voltage , wind current , wind turbine speed ,PV power , PV voltage , PV current , battery voltage , battery power ,charge current .over voltage ,under voltage ,over load, short circuit , night mode, DC output modes etc.
8. Perfect protection function:Solar reverse charge protection, Solar reverse connection protection,Battery overcharge protection, Battery over current protection,Battery reverse connection protection, Open battery protection ,Wind turbine automatic brake and manual brake, over load protection and short circuit protection, thus the system has higher reliability.
9. TVS Lightning Protection.
10. High-voltage wind turbine intelligent buck: The buck module starts automatically when the wind turbine voltage is higher than battery voltage , The controller real-time tracks maximum power of wind turbine and Real-time limits the winding current of wind turbine .To solve the problem of overheating of wind turbine.
11. Impedance matching self-adaption :Due to internal resistance of wind turbine, battery, load, According to the impedance matching principle, The wind turbine will have maximum power utilization rate and maximum power output only when the input impedance equals to output impedance, with impedance matching self-adaption .This controller enhances energy efficiency.
12. Combine the wind turbine open circuit with dump load ,over rotational speed, over voltage, over current limitation
