WindMax H series is the most reliable, most efficient wind turbine with lowest noise level and Incredible 134 mph (60 m/s) survival speed Low noise level, neighborhood friendly: Pole adjacent noise level is < 55dBA, conforming to IEC 61400-11 wind turbine standard for Noise Measurement. 1. Strong Neodymium magnet PMA, unique winding and multi pole design reduces the start-up torque of the alternator that assures the WINDMAX-H series can generate electricity at low wind speed. 2. Advanced aerodynamic braking by patented nylon/reinforced fiber glass blades. 3. Electromagnetic over-speed control, no more problematic mechanical furling. 4. H5 integrated wind and solar power sources capture the most energy in all conditions. solar and wind energy can be mutually complementary in that solar and wind hybrid systems make full use of wind and solar energy together to generate as much power as possible compared to a single energy source for power generation. A solar & wind hybrid system is more cost-efficient than wind or solar alone. 5.
