Configuration: Wind500W plus Solar500W Color: Auto12/24v Product overview A hybrid wind and solar charge controller designed for reliable off grid charging and battery management. The controller combines booster MPPT technology for wind turbine input and MOSFET PWM control for solar input to deliver efficient charging, stable operation, and comprehensive system protection. Key benefits and why you need it Continuous, efficient charging at low wind speeds thanks to booster MPPT for the wind input. Keeps batteries charging even when wind is light. Low controller power consumption and stable solar charging using MOS tube PWM technology. Reduces energy loss and improves long term system performance. Flexible discharge control with stepless dump load support and external dump load resistor for safe dissipation of excess wind energy. Clear system status and easy setup with a color LCD display and four navigation buttons for monitoring and adjustment. Robust construction in aluminum alloy for mechanical strength and wear resistance in outdoor installations. Main features Wind input MPPT: MPPT control algorithm for wind, ensuring maximum power point tracking at low wind speeds. Wind charging stages: MPPT charging, boost charging, floating charging. Solar charging technology: MOS tube PWM with threestage charging: CC constant current, boost charging, floating charging. Stepless discharge function: supports external dump load resistor for controlled dump load operation.
