The Proven Energy 7 wind turbine is the perfect system for Alaska's harsh weather ,strong gusty winds, and remote locations. The unit has the same design and features as the Proven 6kW or 15kW, yet it is light enough to allow for easy transport to remote sites by bush plane or sled. Although this turbine may be small with a 3.2kW output, it is still a Proven with the patented Flexible Blade System enabling the wind turbine to generate power in light turbulent air or dense gusty wind.
Proven Energy has designed and patented the flexible blade system which enables the wind turbine to generate power in light or strong heavy winds up and over 156mph .
- The Proven 2.5EX (explosion proof) is widely used on off-shore oil platforms
- Safety cord through blade and attached to hub for more safety
- Permanent Magnet design for simplicity
- Keeps producing energy in high winds up to 156mph
