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!

10KW Off Grid Wind Generator


Introducing WFD10KW – A 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 WFD10KW is used to charge  240V batteries.   Equipped with suitable DC to AC inverter, it is capable of supplying power for: Refrigeration, Electric fan, Lights, Air conditioner , Communication equipment.

When used in conjunction with a suitable Grid Tie inverter WFD10KW can also be connected to the power grid.



Reliable passive self furling.

Autobrake  slows down the blades spin when the batteries are charged.

Marine quality powder coated aluminium body, water tight housing.

Iron Boron Neodymium magnet alternator.

Reliability: The design of the body efficiently flows excess heat into the wind reducing operating temperature.

Two years warranty; operational life expected to be in excess of 15 years.

Electrical Installation

In most cases the loads will be AC(alternating current) and they will be supplied through a DC-to-AC inverter.


Battery bank

This off grid system should use 8 pieces of 12V/200Ah batteries.

Maintenance free Lead Crystal Battery

New Technology

The invention of the lead crystal battery is a breakthrough in battery history. Based on the composite electrolyte and proprietary intellectual property rights, makes the reaction of the electrolyte formation caused the forming for the crystal state.


1. Ideal green and environmental protection battery.
Lead crystal battery is using special SIO2 composite electrolyte to replace the sulfuric acid solution of traditional lead-acid battery. The electrolyte is non-toxic, non-smell, to surrounding environment.
2. Excellent high and low temperature operating characteristics
Working temperature from -40°C~65°C
3. Easy for depth discharge
Working life of is no effected by the general over-discharge.   Excellent recovery capacity of charge-discharge.
5. Long working life

Lead crystal battery can work for 10 to 15 years,  and charging time is 25% faster than normal lead-acid batteries and gel batteries.

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.
