Hi all, im new to turbines and have jsut aquired a 500watt 24v turbine and controller. The problem im having is when i connect the 3 wires from the turbine which il assume is 3 phase ac, to the controller, it does not freely turn anymore but feels like its braking hard. If i switch the inbuilt manual brake switch to the on position, it frees off slightly but no volts. Now if i only connect 2 of the 3 wires to the controller, then it spins freely and generates volts. Do controllers have rectifiers built in? im guessing they do because the controller has 3 input plugs for the turbine motor.. Any insight to what im doing wrong would be great as now im frustrated as i konw its probably somthing simple (hopfully).
