  Product feature   1.Low start up speed, high wind energy utilization. 2.Easy installation, tube or flange connection optional. 3.Blades using new art of precision injection molding , matched with optimized aerodynamic shape and structure,which enhance the wind energy utilization and annual output.  4.Body of casting aluminum alloy, with 2 bearings swivel , making it survive stronger wind and run more safely. 5.Patented permanent magnet ac generator with special stator,effectively reduce torque, well match the wind wheel and generator, and ensure the performance of whole system. 6.Controller, Inverter can be matched according to customers’ specific needs. Product advantage   1. Generator: Our generator with cooling function. It can not burn out when the wind is too strong. 
2. The wire package in the generator is made of copper wire which can resist 160 centigrade heat. High insulated performance, high magnetic permeability, High generating efficiency. 
3. The magnetic sheet is Neodymium iron boron not ferrite. Neodymium iron with long life time than ferrite and not easy to demagnetize. The stator is made of 470 silicon steel sheet. Not iron sheet. 
4. Blades: Streamline shape three PCS FRP blades, Unidirectional fibre fabric, by use of epoxy resin mold made by hand. Not hollow it is inner foam. Low Noise. No need to adjust and good quality of balance. No shaking. High strength, fatigue resistance. 
5. Controller is solar and wind hybrid, have manul brake button. 200% immediate protection function. 
6. Inverters are ture sine wave, not square wave or Vehicle-bone inverter. 
7. The material of tower is steel tube, PET paint, anti-decaying, antiseptic, rust-proof. Product pictures for reference     Packaging & Shipping
