Wind Generator
WFD1KW

Introducing WFD1KW – A 5 blades wind generator with beautiful shape, safe, portable and reliable. It is especially designed to meet the demand from individual householders for a renewable energy source.

The WFD1KW is used to charge 24V or 48V batteries. Equipped with suitable DC to AC inverter, it is capable of supplying power for:

Refrigeration, Electric fan, Lights, Navigational equipment and .Communication equipment

Features:
Reliable passive self furling
Autobrake slows down the blades spin when the batteries are charged
Marine quality powder coated aluminum body, all stainless steel hardware, water tight housing
Iron Boron Neodymium magnet alternator.
Reliability: The design of the body efficiently flows excess heat into the wind reducing operating temperature
One year warranty; operational life expected to be in excess of 15 years.

Advantages of 5-blade wind turbines over 3-blade wind turbines
1) 5-blade wind turbines will greatly improve annual energy production in low wind conditions.  For areas with average wind speeds of 11 MPH (5m/s).  If you compare annual energy output to conventional 3-blade wind turbine, there is an increase of annual energy output of more than 60%.

2)  5-blade wind turbines will dramatically improve the reliability and safety of the wind turbine.  The blade rotation speed of a 5-blade turbine is 60% of the rotational speed for a 3-blade wind turbine.  5-blade wind turbines will greatly reduce the chance of overspeed control malfunction.  This will ensure operational reliability from a long term perspective.

3) The lower blade rotation speed of a 5-blade wind turbine will lower wind turbine noise and make 5-blade wind turbines more community friendly than 3-blade wind turbines.

Apparent Sound Power Level for the Acoustic Reference Wind Speed

• Turbine Sound Pressure Level at 7.3~8.7 m/s: 66.4~73.8 dB
• Background Sound Pressure Level at 7.3~8.7 m/s: 54.6~66.8 dB
• Different between background and turbine :7~11.8 dB

Test was made at 10 meters from the turbine.
