Consult a local electrical contractor for details and regulations. Made in the USA by: Southwest Windpower, Inc. [. . . ] It is very important that the AIR marine can "sense" the proper battery voltage. 4. 1. 3 Blades The blades consist of an injection-molded high strength carbon fiber reinforced engineering thermoplastic that results in strong lightweight blades. The blades are computer designed to efficiently extract the most power out of the wind. The blade design also provides "overspeed" protection in high winds. In winds moving above approximately 40 mph (17. 9 m/s), the blade tips will "dump" excess wind off and prevent the turbine from over-speeding. 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". [. . . ] If you expect higher winds, shut down the turbine and either lash down the blades or remove the hub and blade set. For a precise indication of charge current you will need to install an amp meter in your system. Why is the AIR marine so powerful for its size, weight, and cost? 34 Almost every part of the turbine has been developed from "the ground up" using 3-D computer models to help analyze every element of the design. As a result, this stateof-the-art turbine features the following: · The AIR marine is the only turbine that uses a permanent magnet (PM) alternator that matches the cubic power of the wind. [. . . ]
