Vertical-axis small wind turbine WS-4 RANGE

helical Savonius rotor

Silent & graceful power generation. The 4B is suitable for highly visible installations in populated urban areas. Likewise, the 4B or 4A is well suited for multi-unit installations in heavy wind environments in remote locations or offshore where a moderate-level of electrical output is required. Cut-in speed and power output at any given wind speed varies depending on generator configuration (Star/Delta) & charging voltage (12/24/48VDC).
