I peaked the voltage output at about 75V with a drilling machine before I screwed up my multi-meter, probably by going over its rated current, but it was producing a cool 24V from a ceiling fan.
I was able to step down the voltage using a buck regulator and charge things, but think I would need to Charge Controller of sorts to better regulate the voltages and give a decent amount of current, especially if the voltages peaks go above 40V which would damage the buck converter.
