Hi, I live in a low wind area and the small alternator I built produces 6 volts at about 250 RPMs which works will the VAWT I fabricated. I am trying to stay away for larger units and tall towers; so I am planning to construct 3 small turbines that are roof mounted and connect them to charge a battery bank. The turbines are low cost and easy to fabricate but I need a circuit that will connect the 3 to get charging voltage that I can connect to dump load charging circuit for charging the battery bank. Will this circuit work? Thanks in advance for any feedback received.

Looks like it should work, You're figuring 18 Volts for total of the 3. It doesn't increase current, but does increase voltage.
