Abstract:
Wind turbine voltage regulation is usually achieved by diverting or dumping excess power into a dumpload (as heat). A universal 4-stage wind turbine dumpload charge controller circuit (inc. resistor load) was designed and built (using veroboard) for $140. Without a charge controller, the wind turbine's main storage battery will overcharge resulting in reduced battery capacity and damage. Exceeding the maximum charging voltage on your 12/24v lead-acid battery system, will overcharge the battery, release hydrogen gas and result in permanent capacity loss.
