We started to manufacture wind turbine in 1994. In 2004, there are only 4 small wind turbine manufactures in China. We keep improving and develop in the small wind turbine field. We are not the leading small wind turbine exporter, but we are the leading wind turbine manufacture and designer now.
We manufacture 300w-30kw fixed pitch wind turbine;
2kw, 3kw, 5kw, 10kw, 20kw, 30kw, 50kw, 60kw pitch controlled wind turbine;
1kw, 2kw, 3kw, 5kw Vertical axis wind turbine;
On grid system/off grid system, wind solar hybrid system; Water heating system;

1. Wind turbine model selection
It depends your local annual average wind speed, daily/monthly home power consumption.
Low average wind speed place, select larger blades rotor, higher rated working voltage;
Rich wind place select speed limited wind turbine: variable pitch wind turbine, stall out vertical axis wind turbine.
The safety and steady working system is the first choice.
2. Wind turbine tower selection
Now we have guy wire tower, stand alone tower, tilting up tower, hydraulic tower.
Guy wire tower cost is lower, easy to delivery. But the installation area is larger;
Tilting up tower is for 500w-5kw wind turbine. Easy installation, small installation area. But the delivery cost is higher.
Hydraulic tower: It is used for no crane place. Easy installation and put down. The cost is higher.
Stand alone tower for the installation place with crane.
The tower height: Make sure blades rotor is higher than wind turbine surrounding barrier height.
3. Working system selection
On grid system: wind turbine with tower + PWM controller with dump load + grid tie inverter;
Off grid system: wind turbine with tower + PWM charge controller with dump load + battery group + inverter;
Wind solar hybrid on/off grid system: Safety and reliable than only wind or solar system.
Wind turbine water heating system: work in rich wind place. Average wind speed higher than 8m/s.
For more question, pls contact with us directly. We will give you a professional response.
