[. . . ] The New 400 watt turbine! Owner's Manual Version 3. 2 2 NOTICES: · This information is believed to be reliable; however, Southwest Windpower, Inc. assumes no responsibility for inaccuracies or omissions. The user of this information and product assumes full responsibility and risk. · All specifications are subject to change without notice. · Wind generators, like other sources of electrical power, must be installed following the guidelines established by state and local regulations. [. . . ] The benefit is that the turbine is able to maintain output, providing you with the most possible power. It also reduces the number of parts, resulting in increased reliability. The only disadvantage of this type of governor is that in high winds the turbine may produce a loud noise. Other turbines have complex mechanisms that either mechanically break the turbine or turn it out of the wind. This can reduce reliability due to increased complexity, and reduce output by as much as 90%. 4. 1. 4 Four Spinning Conditions Of The AIR marine a) Open Circuit 21 When the turbine is disconnected from the batteries, it will "free-spin". In this mode the generator can spin "unloaded" with the wind. At approximately 40-mph (17. 9 m/s) wind speed, the blades will begin to go into an aeroelastic stall to prevent the rotor from overspeeding. In addition, the internal regulator has a high-speed regulation to protect the circuit from high voltage conditions. Operating the turbine in open circuit for a brief period of time will not damage the turbine. However, operating the turbine in open circuit for a long period of time can cause excessive wear to the turbine and is NOT recommended. We recommend that during long periods of operation the turbine should be connected to a battery or the turbine wires should be shorted. Shorting the turbine will minimize wear to the bearings and prolong turbine life and is quieter than running open circuit. b) Normal Operation (Charge) When the generator is connected to a battery bank in need of a charge, the turbine blades will spin "normally" with the wind. The turbine will charge the battery bank as necessary until the battery voltage matches the regulation set point. NOTE: When switched from open circuit to charge, you may notice an approximate 10% -20% reduction in RPM as the generator is now "under load". If the batteries are fully charged the turbine blades will slow to a silent spin. c) Regulation When the battery voltage matches the regulation set point, the turbine will go into "regulation". Blade RPM will lower dramatically and output will stop. (In very high winds there may still be a trickle charge. ) Normal charging operation will resume when the battery voltage drops slightly below the fully charged level. This regulation feature called Hysteresis is explained in more detail in the New Features section (see page 4). d) Braking Braking can be accomplished by directly shorting the turbine negative and positive wires or through the use of a Stop Switch. The Stop Switch will disconnect the turbine from the battery, and then short the positive and negative leads from the generator together. [. . . ] · The blades have aeroelastic twist that provides durability and simplicity. The electronic circuit/alternator allows the turbine to self-regulate. · · Most important, has been the conviction and passion of our team. While overcoming seemingly insurmountable obstacles, together we maintain our desire to help change the world by providing quality renewable energy innovations. 35 · 13.
