I have just returned from a visit to a friend in Burnley (Lancashire) who has a 6KW grid tied Proven wind turbine! What an awesome site it was to see it working away in what I can only describe as gale force conditions that are hitting the UK right now!
I have decided to run my homebrew wind machine tonight in 24V mode and the power difference is scary. I was getting around 80W of power into my battery bank running the turbine at 12V but on 24V charging I am now sat here looking at in excess of 1KW! I guess letting the blades run away a little more makes a huge difference on the power output of the turbine!
Above are a couple of pictures from my visit this evening.
