A "simple" wind turbine system... Horizontal Wind Turbine drives an Alternator (very similar to car's alternator). Goes through a rectifier (diodes) to turn AC into DC power. That power goes through the wiring (and sometimes a switch that can short out the wind turbine to "stop" it for servicing/high winds by shorting the output of the alternator) to the battery bank.
A "diversion" or "shunt" charge controller is attached to the battery bank and the controller's output is connected to a "dump" load--Usually a bunch of large power resistors (basically an electric heater). When the battery is charged, the charge controller turns on and dumps excess power to the resistor bank.
A horizontal wind turbine generally will spin too fast in high winds if there is no electrical loading on the alternator--and will self destruct.
