I'm finally getting around building my 20kw wind generator project. I got a good chunk of the core system sorted out already but I'm missing two components. First, I'm looking for an exciter winding. It's the one that's roughly the size of a dinner plate and about 2inches thick. The other one is a reliable charge controller that can handle the 20kw output. I need something robust and ideally with good MPPT capabilities. I've been on a hunt for these two parts for over a week now. If anyone has leads or any ideas what I can do, I'd appreciate your help!
