Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few wind driven generator manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom wind driven generators has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

Light and small: 350W Hummer generator weighs 5kg, which is about the weight of a hub used in traditional wind generator for fitting blades.
Low energy consumption: Due to small size, less iron and copper used compared with the traditional wind generators, so energy consumption is low.
Low noise: Due to smallness, lightness and efficient rotation controlling (blades never rotor excess 1.5 times of rated speed at any condition) , the noise is low, the blades are more safe and reliable.
Low rated wind speed: For example, 350W Hummer generator can output 350W electricity power if wind speed is 6.5m/s, while traditional similar products require wind speed of 8m/s.
Sure to start with wind of 2.0m/s, and run well in low speed wind.
The nose cone, inside which the generator is set, is made of aluminum alloy, which is very good at cooling.

Streamlined three-bladed glass fiber reinforced blades have the advantages of great intensity, fatigue resistance and high efficiency. The Hummer-patented generator characterizes its high efficiency and good low-speed-performance.
The speed regulating system adjusts automatically to wind speed. The whole system is easy to install and convenient to maintain. Controlling, inverting and discharging are integrated into one system.
