H3.8-2000w windmills wind turbines

Hummer H3.8-2000w windmills wind turbines combines solar and wind energy in one hybrid system. It is well used for street lighting since its safe and reliable. The Model H3.8-2000W Wind Turbine has the great advantages of high efficiency and low rated wind speed. It introduces several patented technologies and uses some special materials.

The off-grid controller adopts the integrated design which consists of the controlling, inverting and load-diverting parts. It fulfills the functions of charging and protection for over charging/discharging, over-loading and short circuit, also supplies a load diversion.

The controller outputs sine wave and has a spare interface for solar energy. Without especial fixation, the controller for 2000W could be connected to the solar panel within 700W.The on-grid controller can connect wind power to electrical grid.

The Yaw Shaft has the equipment of electric slip ring inside which can ensure the free running of generator without cable twisting. Due to the modularization-design, Model H3.8-2000W Wind Turbine is free for maintenance and easy for installation. It can be installed only by the manual work, without welding, concrete or cranes. Even a tyro can handle it easily and swiftly.
