Thanks KS. I can't wait for a decent storm to blow through for a shake down and testing of the system. I had the fiberglass blade set but a better match will be about 14' for this alternator maybe after running it through the winter. Better to error on the safe side to begin with was my thought all along with this experimental build. I'll also need to shut down the solar and burn some AHs to bring the batteries down when the wind comes through, floating often with these Dog days of summer still but that will change. Hope to post an update soon. Dave B.
