1.Excellent Generator: The generator adopts 300W/12V three-phase NdFeB permanent magnet synchronous motor, low noise, and long lifespan. The outer shell is designed for fast heat dissipation. And the external MPPT controller provides you an efficient tracking performance. 2.Low Start-up Speed: The blade is made of nylon fiber, waterproof, corrosion-proof, and lightweight. Temperature bearing is available from -40 to 80. The generator's start speed only needs 2 m/s, and it can automatically adjust the direction to get the maximum wind speed. 3.Easy Assembly: This wind turbine kit will come with the hoop installed, more convenient than the flange. Meanwhile, the blade is accurately designed with the hub and fixing accessories, providing easier assembly for you. 4.High-quality Material: The turbine's body is made of die-casting aluminum, and the tail is made of stainless steel, features of casting shape, model in one, high tenacity. The surface of the turbine is disposed of baking varnish, corrosion-proof, waterproof, and durable. 5.Various Application: With high wind energy utilization and efficiency, the wind turbine can be widely used in charging for home monitoring, motor home, boats, gazebos, chalets, marine, and any other home usage. ******************************************************************************************************* *Specifications Model: VV-FLFDJ-S7-5Y500W12VKZQ Rated Power: 500W Max Power: 500W Rated Voltage: 12V/AC Rated Current: 29A Hoop Diameter: 2in/54mm Rotor Diameter: 47in/1.2m Net Weight: 21lb/9.5kg Blade Numbers: 5 Blade Material: Nylon Fiber Start-up Wind Speed: 6.56ft/s(2m/s) Rated Wind Speed: 42.65ft/s(13m/s) Survival Wind Speed: 164ft/s(50m/s) Rated Speed: 900r/min Working Temperature: -104~176/-40~80 Package Dimension: 27x11.5x7.5in/69x29.5x19.5cm Generator: 3-Phase AC Permanent Magnet Magnetic Material: Neodymium Iron Boron Controller System: Electromagnetic/Yaw Regulating Way: Automatic Adjustment Cabin Material: Die Casting Aluminum with Paint Coated Finish Tail Material: Stainless Steel with Paint Coated Finish ******************************************************************************************************* *Pakcage Content 1 x Wind Turbine Generator 1 x MPPT Controller 1 x Set Screws and Nuts 1 x Instruction Manual 5 x Nylon Blades Steel Pipe Does Not Include
