The complementary wind-solar controller is designed for the wind and solar power generation system, which integrates the control of wind and solar energy. Wind MPPT charging way, make sure power max. input to battery and high charging efficiency obtained. The boost charge function, solve the low charging efficiency problem of low wind speed. Solar charging uses series MOS tube PWM charging technology, which makes the controller's power consumption small and the system more stable. LCD screen clearly displays the voltage and electric quantity of the storage battery, this product is artistic, economical and practical. The humanized keys operate function, all of the parameters according to the request of customers in orders to adjust all kinds of using environment. In high wind speed or wind turbine power is beyond the reach of the battery and charge absorption, the controller immediately launched the continuous discharge function, the equipment protection system. Lightning Protection, Solar Reverse Charge Protection,Battery Open-circuit Protection, Battery Reverse Protection, Over Wind Speed and Over-voltage Soft Automatic Brake Protection, Overload Protection. Perfect protection function, thus the system has higher reliability. size Wind 300W-Light 500W 12V-24V Wind 400W-Light 500W 12V-24V Wind 500W-Light 500W 12V-24V Wind 600W-Light 500W 12V-24V Wind 800W-Light 600W 24V-48V Wind 1000W-Light 1000W 24V-48V Wind 1200W Light 1000W 48V Wind 1500W-Light 1200W 48V
