PWM stepless unload mode
LCD display of solar, wind, battery working
TVS Lightning Protection
Performance: 1. Design for off-grid wind power system. 2. Applicable to different kinds of batteries . 3. PWM stepless unload mode, which burn the excess power into mosfet, making the battery charging in best status. 4. 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. 5. Modular design with simple structure and easy maintenance. 6. LCD display function, visually display wind power , wind voltage , wind current , wind turbine speed ,battery voltage , battery power ,charge current. 7. Perfect protection function:Battery overcharge protection, Battery over current protection,Battery reverse connection protection, Open battery protection ,Wind turbine automatic brake and manual brake, thus the system has higher reliability. 8. TVS Lightning Protection. 9. .Wind turbine output voltage intelligent boost:The boost module starts automatically when the wind turbine voltage is lower than battery voltage , ensure that the wind turbine normally charges the battery.The boost module shuts off automatically when the wind turbine voltage is higher than battery voltage. 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. With press key.User can choose the intelligent boost or intelligent buck according to performance of wind turbine . To ensure the system work more reliable and more efficiently. 10 .Impedance matching self-adaption:Due to internal resistance of wind turbine, battery, 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. 11. Combine the wind turbine open circuit with dump load ,over rotational speed, over voltage, over current limitation: When the total current of wind and solar is higher than limit current point or battery is full , The PWM duty cycle of controller will be decreased untill battery is fully charged. And then controller disconnects the charging loop, the wind turbine will be on no-load operation. In order to prevent wind turbine from propeller racing .This controller is designed with over-current and over-voltage limit, Controller will automatically start PWM voltage intelligent dump-load function once wind turbine rotation speed or wind turbine voltage is more than setting point. So avoid wind turbine constant working in dump-load status, and increase the controller service life. 12. Maximum charging current limiting for battery: User can set the battery capacity and maximum charge current according to systems’ exact configuration . To ensure the battery service life. 13. Wind turbine charging able or enable by manual: Turn on or turn off the charging switch by manual, The wind charging is shut off if choose switch off, The wind charging is normal if choose switch on . To avoid sparks when connection the wind turbine to controller , User can choose switch off .
