Safety system
Safety system by hinged vane which will gradually turn the rotor out of the wind and a short circuit system for the generator. Stop switch – which shorts turbine to dead stop.

With it's near silent operation coming from its carefully designed composite blades the 5kW Montana is ideal for rural homes or business looking to reduce their carbon footprint and actually benefit from the rising energy costs.. * Maximum Output 5.8kW * Rotor Diameter 5m * Annual Yield 9,500kWh at 6m/s * Tower Hieght 12m * Average Turbine Lifetime Over 20 Years * Maintenance Free Direct Drive Design




12m Mast

8kW inverter charger
