I dont know why you are measuring the open circuit voltage of your turbine. You would normally connect the turbine directly to a battery bank with a blocking diode in series. The battery would then hold down your voltage to some where in the vicinity of your battery voltage. You would then use the c40 controller in diversion control mode to take excess energy from the battery when the wind in producing too much energy than your battery can tolerate. The controller in this sense, would be used to control battery voltage by applying a load to the battery bank when it deems necessary to accomplish this. It is all done with voltage set points inside the controller. You will need some form of resistive dump load, possibly a water heating element which will need to be sized appropriately for what you are trying to do.

The c40 controller is rated for use with 12v, 24v, and 48v battery systems. You would only use the controller in charge controller mode with PV.

After reading your post again, you may be talking about some form of water turbine. The same principals apply.
Have Fun!! RoyR KB2UHF
