Would like to build a 24vdc regulator for a wind generator

As it is a 3 phase ac perment magnet I need to keep a load on the generator at all times. So once the batteries reach 28vdc I would then like to divert the power to another usable load.
MikeM1, The max current at full wind speed of the 24v wind generator is approximately 20amps at about 30vdc.
I am not familiar with the shunt regulator, but feel this is the way to over come my problem.
The real problem is that my inverter has an over voltage cutout at 30vdc. Hence when the wind generator gets up just over 30vdc my invertor shuts down. What I would like to do is regulate it around 29vdc as I have no problem taking the batteries upto this voltage as it is supposed to be good for their long term life expectance.
Here is a basic adjustable shunt load voltage regulator circuit.
By adjusting the on and off voltages it will be possible to set the load bank to cycle full on at a high point voltage but not disconect until a lower voltage is reached.
I also posted a cheap but efective way to make load resistors in the **** chat area under Dumpster diver tips and tricks.
This should give you a basic but simple and reliable way to regulate your voltage with a load.
