    I have a windblue DC-540 Low Wind Permanent Magnet Alternator. I live in a low wind area.

    Five HyperSpin blades will do the trick. You can also use three HyperSpin blades if you have decent wind.

    I am kinda confused between choosing the 28" HyperSpin Blades with 17-mm Delco hub (set of 5) which they say deliver more torque at a lower start-up wind speed but less rpm and the 24" turbo torque (set of 3) which also is for low wind areas but deliver less torque at start up but more rpm?

    So what u think? My area frequently get a lot of low wind speed.

    Using the 24 inch TurboTorque Aluminum (3 blades) with the Windblue DC-540, how many RPM may I expect in a 9mph wind?
  5. the hypersin blades will do it

    Yes they will. I ran a Wind Blue last year with them on it. I got ride of the Bind Blue but the WN 5 blade HS set doe it big time justice. The most i seen out of the Wind Blue was 20 amps at 12v. Not to impressive for the PMA. Model 540 PMA.
    Good Luck
