3KW wind turbine generator
1. Application:
Wind turbine is an equipment to convert wind energy into electric power which is charged into storage battery group or interface to utility grid. It can be widely used in rich wind areas.
Now we have 48v-240vdc off grid working system, wind solar hybrid system. It is capable of providing power for lighting, TV, washing machine, refrigerator, small water pump, air conditioner, telecommunication equipment and so on.
On grid working system 120v-500vdc: wind turbine output 3 phase AC power, PWM on grid controller convert AC to DC and supply steady DC voltage to grid tie inverter. The power can be use for home appliance, extra power interface to the utility grid.
2. Structure
3kw wind turbine off grid working system including: wind turbine main body( blades rotor, permanent magnet generator, rotor body, tail rod, tail vane), guy wire tower or tilting up tower, charge controller with dump load, battery group, inverter.

5. Wind turbine main features
- Blade: Manufacturing according to the airscrew structure principle and techniques. Optimal wide TSR & High L/D ratio. With protection film on the edge, long work life.
Select blade type by wind tunnel testing. With high efficiency, low noise.
- Blades rotor: Hub adopts casting molding; Blades rotor and generator adopt universal connection, directly driven. Connection is reliable, durable, smooth operation without vibration.
- Generator
Rotor: Nd-Fe-B permanent magnet. Prefabricated tangential magnetic circuit rotor; High magnetic flux density, small cubage, good manufacturing process and high performance.
Adopt SKF, NSK bearing.
Close transmission slip ring, the cable will not enlace.
- Speed regulation: yaw. Simple, reliable and safety.
- Anti-corrosion treatment: All the outside parts are designed to anti-salt, anti-fog, anti-atmospheric anti-sandstorm corrosion design.
- Tower: guy wire tower, tilting up tower, standalone tower, hydraulic tower… It can be designed according to your request.
- 300w, 500w 1kw, 2kw, 2.5kw auto braking; 3kw-30kw auto braking system and manual braking system.
- Wind turbine design principle is simple, safety, reliable, maintenance free.
- Provide low wind place, rich wind place solution. Wind turbine OEM service.
