My first wind turbine went up Sunday. After two days of no wind, I got two days of 10 to 20 mph winds with gusts between 20 to 30 mph its holding up well. I'm going to have to take it down soon to better balance the blades. I've found I need more batteries though, I thought 8-100 amp hour batteries would but enough for now.

Balance is quite an art, get the tip runout, tip to tip measurment and angles as perfect as you can.

Try it and see just doesnt cut it, they will demolish bearings quickly otherwise.

Solution to batteries is having something to run
-800AH is lots of batteries, more than enough for all but a full standalone system.

set up some lights for starters. pumps also good, more water to somewhere higher etc.
Heat hot water second last resort to dumping to free air

Luck favours the well prepared
