750W Off Grid Wind Generator

WFD750W 

Introducing WFD750W – A 5 blades wind generator with beautiful shape, safe, portable and reliable.  It is a small wind turbine with 2.10 m diameter rotor and can be used on land or on larger vessels.  It includes a 750W battery charge controller which will brake the turbine and stop charging automatically when the batteries are charged full.  The WFD750W is used to charge 36V or 48V batteries.   Equipped with suitable grid tie inverter, it can also connect to grid.

 

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.
