Feature: 1. Low start?up wind speed, high utilization of wind energy, small size, low operating vibration. 2. The main body adopts hoop connection, enabling fast and convenient installation and assembly. 3. The blade is made of high?strength PA66 and fibre?reinforced nylon with good toughness, very durable. 4. The permanent magnet generator with a special stator design can effectively reduce the resistance torsion of the generator. 5. This generator adopts an external controller, which greatly enhances the safety and stability of machine operation. 6. Solar energy systems can be used to generate electricity together, and forms an excellent wind?solar power generation system.
