Generator Body
Features high-grade Neodymium Iron Boron permanent magnets, each tested for magnetic flux by authorized institutions. Engineered for low starting torque while maintaining high generating efficiency through optimized internal structure.
Blade Specifications
Streamline shape with 3 reinforced fiber plastic blades. Manufactured using unidirectional fiber fabric and epoxy resin molds with inner foam core construction. Designed for low noise operation, excellent balance, and superior fatigue resistance.
Wheel Hub & Connectors
Precision-made steel wheel hub connects blades to generator. Blades connectors constructed from Q235 plate with anti-corrosion surface treatment for durable performance.
Tower Options
Available in Q235 guy wire tower with anti-corrosion painting or free stand tower with hot dip galvanized plastic spraying for various installation requirements.
On-grid Controller
Brake function activates when issues occur in on-grid inverter and disconnects from the state grid. Controller delivers stable current even in strong wind conditions with comprehensive indicators including wind energy, unload, delay stop, under voltage, and grid electricity. Features emergency brake button for forced rotation stop.
On-grid Inverter
Utilizes IPM from Mitsubishi as power components and American ATEMEL company microprocessor as figure controller. Features perfect protection, warning functions, MPPT (Maximum Power Point Tracking) technology, pure sine wave output, automatic grid synchronization, power factor close to 1, low harmonic content, and non-polluting power grid operation.
