This would be my recommendation. SunG 300 - 500 Watt Wind 1. Goes to dump too fast if sudden change in voltage. 2. Will let turbine free spin while recalculating. 3. BIG gusts will fry dump mosfets. SunG 1000 Watt Wind 1. Does not suffer any of the problems except maybe Burning up mosfets during BIG gusts. I do not know as I have a switch to a external dump load to protect the mosfets and do not use SunG dump load terminals . Contact Leamy for anymore information on Battery-less Grid Tie Setups.
