would this work..?you have a wind turbine and want 27-33 volts( 24v battery) out of it but not more. You dont want buy a clipper or controller.
so you run your 1- 6 ga wire into 5 smaller wires.You use components to get the voltage to divide evenly among the wires. 30v becomes
6 v each on 5 wires.On 1 of the wires you put an exit to ground thru a 7 volt zener diode.So as the voltage rises to 7 volts per wire that wire bleeds off its 7 volts.That gets you down to about 28.You also put a 10 volt zener( rough estimate) on another wire so at 50 volts you would lose 17 volts total and get approx. 33 volts. (these values are not exact).You would have to combine the voltages again before the charge hit the batteries. What do you think of this way to avoid overvoltage...??
