Suzhou Yueniao Machinery & Electronics Imp & Exp Co Ltd is one of the pioneer renewable energy business and has been in this field since 2002. We are dedicated exclusively to the business of small wind generator, mini hydroelectric generator and solar energy. As a manufacturer with advanced technology, we are making in our own workshop the wind turbine from 300w to 20kw with CE certificates. Beside that we are dealing with business of mini hydroelectric generator from 200W up to 60KW and solar panel from 20W to 280W. We do not claim any of its products to be the best, but we are proud to hear the owners of our products praise them. And that is what makes all the time and effort we spend on our products worthwhile. Thank you for your support!

Wind Generator


An attractive, reliable and economic source of electricity for remote areas.  Enough power for lights, radio, television, fan, kitchen appliances, microwave oven, washing machine, power tools and more, depending on the average wind speed.  The ideal source of power for telecommunications and scientific equipment.

The WFD500W is used to charge  24V/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.

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.



  1. 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.
  2. Variation: All values are nominal as there will be some variation in manufactured product.  Specifications subject to change.
