Premium Quality: This brand-new wind turbine controller is constructed with high-quality materials, ensuring durability and reliability. The brake circuit and rectifier are designed with an integrated module for enhanced performance and extended service life. Fully Waterproof: Designed with full waterproof protection, this controller meets an IP67 protection level or higher, making it suitable for harsh weather conditions. Automatic Control: The controller enables automatic battery charging from the wind turbine. When the battery reaches full charge, the internal circuit automatically engages the braking system. Charging resumes when the battery voltage drops to the recovery level, helping protect both the battery and the turbine.
