12V 24V 400W Low Speed Household Vertical Wind Generator Roof Price

Security. Using vertical blades and triangular double-fulcrum,The problems of blade lose/broken or leaf flying-out have been well solved.

Noise. Horizontal rotation and aircraft wing design reduce the noise to an unperceivable level in natural environment.

Wind resistance. Horizontal rotation and triangular double fulcrum design make it only bear a small wind pressure even in strong wind.

Rotation radius. smaller rotation radius than other types of wind turbines, space is saved while efficiency improved.

Power generation curve.The power generation increasing gently , it could produce 10% to 30% more power than other types of wind turbines.

Effective wind speed range. special control principle expended the wind speed to 2.5 ~ 25m/s, utilizes wind resource effectively and obtains a higher power generation.

Brake device. The blade itself has speed protection, and can configure manual mechanical and electronic brake meantime.

Operation and maintenance. Without gear box and steering mechanism, the wind turbine only needs regula check every 6 months.
