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 )
Airforce4.1 48V off-grid 220V/380V on-grid
H10kw--30kw 240V on-grid or off-grid
H18-50kw 380V on-grid or off-grid
Q4: What thickness of pole would we use for your horizontal wind turbine and what would be the height approximately of the section that we would add on to your unit?
A: We recommend to use 3mm-5mm thickness, 8m height guyed cable tower or 5mm-8mm thickness, 8-24m height free standing tower or hydraulic tower for our HAWT 1KW-50KW. Please contact our sales to get more tower information.
Q5: How is your HAWTs to realize the security protection during heavy winds?
A: There are multi security protection to ensure our HAWTs speed regulation and protection during high wind: yawing + electromagnetic brake (by controller) + manual brake (available on HAWT 5KW to 30KW models).
