System Circuit Diagram:

off grid wind turbine system diagram


Wind turbine off-grid system: which consists of wind turbine(s) to generate unstable electricity, through a off grid charge controller to rectify the electricity from the wind turbine into a stable DC, and then keep charging and storage in the battery bank. You will then need an off-grid inverter to convert the DC electricity stored in the battery bank to AC electricity and supply power for the home & business etc appliances. Our packaged systems are ideally suited to remote areas homes, schools and other off-grid applications. They can also be retrofitted to existing diesel generator systems to save on high fuel costs and minimize noise.

Or connect with solar panels to get a wind/solar Hybrid system:

Over-speed Control System

Smart Blade Aerodynamics Braking and Electromagnetic Speed Limitation

3kw wind turbine generator         3kW wind turbine power curve

This power curve generated by wind tunnel testing indicated that the blade aerodynamics braking system starts to take effect from 14-15m/s wind speed, the rotor RPM is always limited within wind turbine rated maximum RPM at even higher wind.


Abandoned the traditional failure-prone mechanical furling system, the blade itself is designed with over-speed braking system which will generate a reverse reluctant torque to lower the blade rotation speed so that the blades and generator can be well protected in higher wind, it solved safety and reliability problems facing by most small wind turbines.


Combination of electromagnetic braking and aerodynamic braking maximizes energy capture by extending turbine’s operating speed range into higher and lower wind speed which are missed by the old style wind turbines.

Maintenance Free Design

Innovative two-moving-part system

Typical wind turbine has three moving parts (rotor, head yawing and mechanical furling), we replaced mechanical furling by using advanced electromagnetic and blade aerodynamics braking and take only two moving parts, which improve generator reliability dramatically as it has less mechanical failure.

Innovative slip ring design

Wind turbines with typical slip ring design often twists and tangles the connection cable from generator to controller, which made the system has to be maintained every few month. We patented slip ring design solved this problem completely and made our wind turbine with higher reliability and real maintenance free.

Best Material and Workmanship

Rotor and housing

Patented rotor is made of high quality stainless steel rotor shaft attached with permanent neodymium magnet, the unique winding and multi pole design reduces the start-up torque of alternator which assures generator would produce more power at lower wind condition than other system.

 wind turbine rotor and housing

Generator housing is made of precisely casted aluminum alloy with minimal tolerance and sealed with high quality sealant, this is why our wind turbine could work normally under varlous working conditions, and this is why our wind generator features class B insulation and OP56 class protection. Besides, our generator system is designed with a sufficient buffer of overload to ensure overall wind turbine reliability.
