Have no idea on the specs of this thing, but was here when I got the property.
Last owner said he had to recently replace the bearing on it. No surprises really, because it had literally been connected straight up to a 24V battery bank with no charge controller and he thought this thing was working!
I only measured about 12-15V DC when the thing was running.
So I took a look at the box on the ground that the DC cable to the battery bank connects to and found it was not only unsealed to the elements and had vent holes and contained 3 bridge rectifiers, one to each phase, see photos.
This won't do anything to charge the battery, but the problem I have is I will have to charge the battery from 30m of cable to the bank, as there are only 2 wires buried to the turbine, when ideally it should have been 3 wires, one for each phase, sending AC down to the battery bank with less losses and place the charge controller near the battery.
Do I place a proper wind turbine controller at the turbine itself in a sealed box and run 30M of cable to the battery? Or place a new bridge rectifier there and hook up to an MPPT solar controller instead at the battery?
Main issue is addressing a dump load too.
Not sure how I go about this without the right controller.
Is there a way to easily convert the 3 phase output into single phase and then place the charge controller at the battery?
TIA
