Working System: Wind and solar charge controller adopts MPPT boost charging function, which make it charge continuous and efficiently even in 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. Dual Power Supply: This kind of dual wind charge controller is special design for small off-grid he course of which wind genrator and solar panels charge to batteries safely and efficiently. LCD Display: Clear LCD screen can clearly display parameters such as voltage and current of wind, solar and load. Besides, it also has four key operation functions. Customers can adjust parameters according to their own requirements to adapt to all kinds of using environment. Excellent Design: The inner circuit board of the hybrid charge controller is sprayed with conformal coating to prevent dust, moisture and static electricity. The controller's power supplies use high-quality imported components to ensure excellent controller performance and stability. Perfect Protection Function: Wind solar hybrid controller has multiple protection functions such as reversed charging Protection of solar, reverse polarity protection of battery, battery open circuit protection, lightning protection and over voltage over current over load voltage protection.
