In my search for a well made charge controller that would allow me to configure it properly, I came across Karasouli –  It’s easily configurable, and also does proper data logging, for voltage and wind turbine performance, and its made in England, which is rare, but good.
Once all the related bits and pieces arrive from around the globe (does no one make a decent brake switch outside of the USA?), I’ll get it all hooked up and start collecting data.
