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!

30KW Grid Tie Wind Generator System

WFD30KW-4 (7.5KW x 4)

Reduce or Eliminate Your Electricity Bill
Introducing WFD30KW- 4 – A new generation Residential Power Appliance that hooks up to your home to help you reduce or eliminate your monthly electricity costs.

WFD30KW- 4 is designed for homeowners looking for a quiet, convenient, affordable way to protect themselves from ever increasing electricity costs.  It includes wind generator, controller with dump load and grid tie inverter.   With no batteries, WFD30KW- 4 connects directly to your home.  When the wind is blowing, your home is powered (in part) by WFD30KW- 4; when it’s not, your home is seamlessly powered by your utility as usual..  If the wind speed is too large, part of the dump load will be connected to the wind turbine to keep the constant power to fed in the utility grid.


And you do not need the most disposable part of a wind power system --- the batteries. 

This system consists of 4 x 7.5KW wind generators with controller and
1 x 30KW grid tie inverter.
