Feature: 1. Low start-up wind speed ensures stable and reliable operation with high wind energy utilization rate. 2. Adopting flange installation, the quick assembly of this wind turbine is very convenient. 3. The blade is made of high-strength PA66 and fibre-reinforced nylon with good toughness, not easy to deform in long use. 4. The special stator design can effectively reduce the resistance torsion of the generator. 5. Comes with a controller, which guarantees the stable, safe and easy operation of the wind power generator. 6. Can combine with solar energy system to form a perfect complementary wind-solar hybrid power generation system.
