SD6 Wind Turbine

The SD6 6kW small wind turbine is our most popular model. It has been the best-selling small wind turbine in the UK and is regarded as the turbine of choice world-wide for over 25 years.

Available as Grid-Tied and Battery Charge, the SD6 small wind turbine is designed for those with a high energy demand, or for applications that require a greater level of power autonomy when used in an off-grid or hybrid system.

The unique over-speed protection system, the delta rotor, ensures continuous energy generation during extreme winds. This provides excellent value to users of this durable and reliant small wind turbine. As wind speeds increase, the SD6 will maintain output and performance. When compared to alternative wind turbines, which need to brake themselves in strong wind conditions, the SD6 is the small wind turbine of choice. Continuous energy output and performance delivered.
