Use for Housing use ,public lighting system ,communication base station ,sewage disposal station,toll station  and Controller and indicating system ( traffic signal ,road condition signal ,security surveillance and forest fire prevention ) and other project .





Q1: Are you factory or trade company ?Where is your factory?

A: We are professional wind turbine factory,specialized in designing and manufacturing wind turbine for 12 years .We are in zhuhai city ,Guangdong province ,near to Macau and Hongkong (15--60mins by ship ).


Q2: Is the wind turbine price listed above include the charge controller and others? If not,where I can purchase the controller and inverter?

A: The listed price is just for wind turbine only (generator + blades), no including controller, inverter and other parts. Please contact our sales for the controller, inverter and other system parts for on grid and off grid application.


Q3: What is the working voltage of your HAWTs for my battery bank or grid utility?
A: Please find our recommended working voltage as below:

300w--12V off-grid 

Airforce1.5 600w--12v/24V off-grid 

Airforce2.0L/Airforce2.0 ---24v/48v(off-grid )/110V(0n-grid )
