Sturdy and Durable: It adopts a permanent magnet generator with an iron core paired with two aluminum alloy blades, and the surface is sprayed with plastic, which can withstand bad weather and ensures the product's long and stable operation. Efficient Work: It has a power of up to 100W and a wind speed of up to 42.65ft/s, and the starting wind speed is lower than that of other wind turbines, and the power generation increases gently, so it can generate more power than other wind turbines within a certain range. Safe and Reliable: It adopts a permanent magnet rotor alternator with a special stator design, which effectively reduces the torque resistance of the generator, and at the same time makes the wind turbine and the generator have more favorable matching characteristics and the reliability of the unit operation. In addition, it will automatically brake when it reaches the maximum speed of 300 revolutions per minute. Low-noise Operation: Adopting a precision double-bearing design and a quiet and reliable rotor, it effectively reduces the operating noise, which is less than 62dB, not affecting the tranquility of the surrounding environment. Easy to Assemble: Clear installation instructions are provided to help you get started and complete the installation quickly. In addition, the humanized flange mounting design makes the installation, maintenance, and overhaul of the equipment more convenient. Details  High-quality Controller: It adopts a high-power tracking intelligent microprocessor controller to effectively regulate the current and voltage. Spiral Design: It adopts the spiral design principle, rotating in the horizontal plane brings low wind pressure, which can withstand super strong typhoons. Application It is suitable for home, business, and industrial energy supply in boats, gazebos, cabins, or mobile homes, and on top of streetlights.
