A wind turbine is a long term investment. Before you purchase a wind turbine, the first factor to consider is if the energy produced by a wind turbine can pay for itself in 10 years or less. The second factor to consider is installation and ownership cost. Poor reliability, low quality and high maintenance will greatly increase ownership cost and make the wind turbine impossible to pay for itself. The third factor is environment and safety. A wind turbine should be safe for high winds, quiet and have no vibrations to make it residential/home friendly. WindMax wind turbines can meet the above requirements and do much more: * Designed and built by an experienced wind turbine technology R&D team that are committed to innovation and quality. * CE and ISO certified * Amazingly quiet operation with little or no vibration. * Reliable two-moving-part maintenance free design. No problematic furling. * Fully automatic with blade aerodynamic braking and controller electromagnetic braking. * Safe operation at high wind. Survival wind speed is up to 134 mph (3 blades models). Old style fiberglass blades make the old style furling based wind turbine a hazard at high wind. * High efficiency is achieved by matching the design of the generator and blades. * Patented Blades with twisted aerodynamic design and high efficiency are made using the latest advanced thermoplastic engineering and precision injection molding technology for highest strength, performance and durability. * Easy installation, no welding needed. Pole connector provided for standard Schedule 40 2 pipe pole. * High quality generator design with strong neodymium magnets. Every magnet must go through stringent tests before use ! * The blades are made of high-strength Nylon-fiberglass materials. They are not the hollow fiberglass blades which are dangerous in high wind and need to be replaced in a couple of years. Rated 400W @ 12 m/s or 26 mph Maximum Power: 600W with wind/solar hybrid Blade Diameter: 4.6 Feet ....read more
