Primus air 40 hookup questions

PoolguyPoolguy Registered Users Posts: 10
I am thinking of purchasing an air 40 to experiment and mess around with. I am confused as the literature says that the charge controller is built in. Do I just hook this directly to my battery bank? I have solar now with a charge controller and could I just hook this directly to the battery bank and not damage my existing solar charge controller?

Also if I use a stop switch, does this use some current to keep the blades from rotating? How much? If I have the stop switch off for say days or weeks how does that work?

Any help or insight would be very much appreciated!

    In general, you just connect the wind turbine (with internal charge controller) to the battery bank.

    If you want a stop switch, you usually use a double throw switch. First position power from + turbine to + battery bank (and fuse/breaker).

    Second position, power from turbine + to turbine ground--That short circuit current (should) put a lot of torque on the turbine and stall the blades.

    See page 21 and beyond in the Primus manual:
