Mostly DIY Wind Turbine

I thought I'd have a go at making a wind turbine.

The main stages of the first working model are

Head unit rectifier
Incoming power measurement and barrier diodes
Charge controller
Divert load

Here's the alternator and head unit. It's a one kilowatt stepper motor for the alternator, mounted on a half-inch steel plate. The head unit you see on the left contains three 35A bridge rectifiers.

Next is the incoming power box, pictured from the top to show the three 30A Schottky diodes wired in parallel for a maximum capacity of 90A which stop the juice coming back out and trying to turn the alternator.

Here's the charge controller and battery condition monitor

And it all fits onto The Renewable Trolley....
