Hi, thanks for the comments.
Roy, I'm located in Finland.
Flux, I also suspect that it is actually generating the 30A in lower winds than before, but it's hard to say for sure, as i don't have any kind of windspeed/power logging. For sure, it's now running better out of stall.
I didn't perfectly understand the ground failure part. It shouldn't ever be a problem, as the AXMKA4x16mm^2 aluminum cable is meant to be buried without any other protection. Stator circulating current heating should also not be a problem, as I'm rectifying all the 10 coils individually, if that is what you meant.
