20KW Wind generator:
1. Pictch controlled wind turbine
2. Mechanical brake and active yawing
3. Generator galvanized
4. CE and ISO certificate
5.10 years warranty
New technology pitch controlled 20KW wind turbine generator system:
FD-E series 20KW wind turbine generator with pitch controlled protection, and electromotion slewing drive system. With 10 years long time protection for the wind generator. The generator is galvanized with 25 years anticorrosion life span.
Advantages:
1. Generator, cabin, hub etc. All are galvanized processing with 25 years anticorrosion lifespan
2. Generator bearing is fully sealed design for easy oiling and cleaning
3. Generator bearing lifetime is more than 303680H (25 year)
4. Patented technology ensure generator high output when in low wind speed
5. Generator with strong overload capacity which could run in 2 hours when overload is more than 50%.
6. Generator insulation class is F.
7. MPPT function ensure the maximum power output.
8. The safety factor is high because solid of revolution output torque up to 10KNM.
9. Solid of revolution is fully sealed design and lifespan is more than 25 years.
10. Mechanical brake system is drum brake, which is high stability and strong brakeage.
11. Cabin fully sealed design, good waterproof.
12. Space in cabin is large. It has a maintenance entrance in the cabin for repair, maintenance which reduce the maintenance cost.

Foshan Ouyad Electronic Co, Ltd was founded in 1998, covering an area of more than 20, 000 square meters. We have our own independent wind turbine manufacturing plant and R&D department of wind turbine generator control system, solar panel, grid tie inverter, off grid inverter, battery, etc. The headquarters are located in Guidan Road, Nanhai district, Foshan city with convenient transportation. At an early time, our company was famous for producing a variety of inverters at home and abroad. In 2005, we began to R&D and produce new energy products, and set up R&D center in Shenyang, R&D generator and brushless DC generator, and obtain great success, with 15 terms of new patents have been reported. Depending on powerful technical strength and many years manufacturing experience, Ouyad has rapidly developed into a new energy production manufacturer with a core of wind turbine system research. Our company established marketing sales and service center in Washington State in 2010. Ouyad was CE certified and has passed ISO9001 international quality management system certification, and UL certified is being tested. Our company has possessing a large of professional, and we have advanced production facility and professional inspection(testing)equipment.
The main products include the main classes:
1. Wind turbine 500W to 200KW (generator+ blades+ tower), etc.
2. Controller: (PWM&MPPT, optional)
