I purchased this wind turbine a few months ago, its excellent, first I went to hardware store and bought 1 1/2" fence post threaded pipe with two 1 1/2" threaded braces and 4 bolts that fit the wind turbine main structure. Put it together, crimped an ac three wire outdoor extension cable to the turbine. Put black garden water tubing over extension cable to protect it. Crimped three connectors to the end of extension cable, connected extension cable to alternator rectifier, connected two dc cables to rectifier and connected those cables to my solar combination box. I've been making (depending on the wind of course) anywhere from 1.5 to 22 volts dc since. I get the Renogy smiley face in the middle of the night lol.
