Application This product is suitable for home, business, and industrial energy supply for boats, gazebos, cabins or mobile homes, and the tops of streetlights. Package Included 1* 12V/24V Vertical Wind Turbine Generator 1* Controller Other Needed Accessories Long Service Life: The product adopts nylon fiber, aluminum, copper, stainless steel, and the plastic spraying process, making the product resistant to corrosion and impact, making it hard to deform, and keeping it glossy and practical for long-term use. High Efficiency: The 5.59mph low starting wind speed, 100W high power, and powerful copper wire permanent magnetic levitation motor allow this product to efficiently utilize wind energy to generate electricity. Reliable Design: The permanent magnet levitation generator is characterized by low loss, high power, and low torque during start-up, ensuring high power conversion efficiency and smooth and reliable operation. Simple Installation: The product adopts a humanized flange mounting design, which makes the installation, maintenance, and overhaul of the equipment more convenient. Thoughtful Design: The product adopts an intelligent microprocessor controller to effectively regulate the current and voltage. In addition, the product comes with an automatic braking design. When the product reaches the braking voltage (14.4V/28.8V), the speed will be reduced, until the voltage drops to about 12V/24V and then speed up, and so on and so forth to ensure stable and safe operation. Details Nylon Fiber Blades: The blades are made of premium nylon fiber, which is strong and durable with excellent aerodynamic shape design, reducing the starting wind speed and improving the efficiency of wind energy conversion. Spiral Structure: The product adopts the spiral structure, making the product rotate in the horizontal plane to bring low wind pressure to withstand strong typhoons.
