I'm having trouble following U guys...sorry.

As it stands, the image is my understanding of what your saying.

....am I close? If I'm understanding this correctly, the Windmill DC current is connected directly to the battery. The battery can cope with this because it is self regulating.

The Shunt regulator I have monitors the battery for full charge. When it detects full charge it dumps the load by placing a load on the battery - dump load needs to be at least same capacity as the power the gennie is capable of producing.

The regulator also monitors battery for low voltage and turns off the shunt load so battery can recharge.
