To overcome the shortfall of self-start for Darrieus¹ type of VAWT and poor

efficiency (Cp) from Savonius² type of VAWT, Hi-VAWT has integrated

both designs into DS Series VAWTs that offsets the disadvantage over

each other.

Advance Generator Design

Direct drive coreless PMG in extreme low startup torque without clutch and

motoring.

Integrated Blades Design

With integrated lift and drag type of design to provide low wind self-start and

high wind efficiency.

High Performance Controllers

All DS-Series wind turbines are equipped with special designed power

controllers with built-in MPPT function to maximize the power generation.

For safety control purpose, both DS-3000W and DS-1500W also equipped

special designed control box.

• Excellent wind direction adaptability, fit to Install at urban area such as roof of building.
• Excellent Turbulence Compliance.
• Genius low wind self-start and excellent high wind efficiency.
• Extremely silent.

Remark:

• Named after the French inventor, Georges Darrieus.
• Invented by the Finnish engineer Sigurd J. Savonius in 1922.
