750W Off Grid Wind Generator
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.
It is especially designed to meet the demand from individual householders for a renewable energy source.
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.
Reliable passive self furling
Auto rake slows down the blades spin when the batteries are charged
Iron Boron Neodymium magnet alternator.
Reliability: The design of the body efficiently flows excess heat into the wind reducing operating temperature

Claims & Return Procedures
In order to be eligible for service under this warranty, the Customer must send us pictures showing his installation of the system in 5 days after the installation.
If any problem takes place within the warranty period, Notification must be provided including a description of the alleged defect, the manner in which the wind turbine was used, the serial number, and the original purchase date in addition to the name, address, and telephone number of the party requesting warranty service.
Power Curves and Annual Energy: The performance of wind turbine systems is impossible to predict with any certainty due to the variability in the wind from location to location and from year to year. These estimates are based upon the best available information but are given as guidance only and should not be considered as a guarantee. For a greater level of certainty we would recommend on-site wind speed monitoring for at least a year.
Variation: All values are nominal as there will be some variation in manufactured product. Specifications subject to change.
