My friend has a African12ft grid tie machine for sale complete with windy boy inverter an voltage clamp.
He is asking 3500 dollars for it.
He is selling it because it was mounted in a very bad location. behind a hill. And on a monopole tower.
After having it installed the tower was wobbling to much so they filled the tower with concrete.
It stopped the wobble But now the wiring had to be brought out just below the turbine. So
every time It twisted up he needed to have the crane come back .
Costing more in crane work than the output.
I have seen It working and it worked really well when the wind came from the right direction
