At low wind speed, the wind turbine input voltage is lower than the battery, MPPT function can help solve this problem and can allow the wind turbine to be able to charge the battery at low wind speed and low RPM. 2、Comprehensive Protection: MPPT boost controller is available for 300‑800W wind turbines. Helps to automatically control wind turbine charging batteries. When the battery is fully charged, the brake can automatically take effect. 3、Fast Heat Dissipation: The controller adopts heat dissipation wind tunnel with heightened design, which effectively solves the heat dissipation problem of the controller in the case of high current charging. Safe and stable working condition, with heat conductive silicone potting treatment, sealed and waterproof, dustproof, anti circuit oxidation. 4、Automatic: The wind turbine controller can automatically match 12V or 24V battery. It controls the voltage and current limits during charging to ensure the best charging effect. At the same time, it provides maximum protection for the wind turbine and the battery. 5、Clear LED Indicator: The wind turbine controller has LED indicators to clearly view the working status of the controller. The rating reaches IP67 or above for full waterproof protection. Also includes automatic overvoltage braking, battery reverse connection and open circuit protection.
