1.HIGH-QUALITY BLADES- The blade material is made of nylon fiber blades. The fashionable spiral blade is also designed with aerodynamics to make the rotor run smoothly, reliably, and quietly. 2.EXCELLENT PERFORMANCE- Designed with three-phase AC PMG, the turbine generator boasts low torque, high-power tracking intelligent microprocessor that can effectively regulate the current and voltage. It obviously increases wind energy utilization and annual power generation. 3.COMPACT & FIXED- With dual bearings, the fan movement is more stable. Low vibration and low noise. In addition, with its compact shape, it has the lowest starting wind speed and a larger windward area, enabling it to generate electricity at lower wind speeds. 4.EASY INSTALLATION- All things you need for installation are included. Humanized and convenient hoop design(not required welding), easy to install and maintain. DIY installation methods with all materials provided. It can be used in conjunction with solar panels. 5.MULTIFUNCTIONAL USE- It is the ideal power supply system for scattered households, posts, weather stations, communications base stations, highways, scenic spots, and other places. Well suited for the leisure sector, it is famous for battery charging on boats, gazebos, chalets, or mobile homes. ******************************************************************************************************* *Specifications Blade Number: 5 Blade Material: Nylon fiber Wind Wheel Diameter: 1.19 m (3.9ft) Rated Wattage: 500 W 12V Max Wattage: 510 W Start Wind Speed: 2.0 m/s Rated Wind Speed: 13 m/s Safe Wind Speed: 50 m/s Magnetic Material: Neodymium iron boron Cabin Material: Die-casting aluminum alloy Generator: 3 phase AC PMG Wind Direction Adjustment: Auto adjust ******************************************************************************************************* *Pakcage Content 1 x Wind Turbine Generator 1 x Charge Controller 1 x Product Manual Battery/Switch/Steel Pole are not Included
