    My employer has a strange idea that the voltage regulator/low voltage disconnect which he imports from China can somehow be used as a shunt regulator for a 400 watt wind generator. He wants a sensing circuit to short out the wind "genny" at a given battery voltage. This sounds ridiculous. What do contributors to this forum think about this? Thanks.

    A shunt regulator can be used if dynamic braking of the wind generator is desirable. It is not a "short"; the shunt regulator bypasses the current from the generator to ground while holding the voltage constant (same as the voltage across the charged battery). This wastes the power being produced by the generator as heat, but it does keep the generator from running away. Putting a short across the generator may produce the desired dynamic braking; a diode could prevent the battery from discharging backwards into the short...
