One of the turbines I'm playing with came in missing a charge controller and was damaged a little. The seller is reimbursing me $125 to rectify the situation. The damage can be remedied with a hammer, though it won't be pretty to look at...wind don't care, though. So I can drop the rest on a charge controller setup.
The goal is keeping a 24v battery bank charged, might eventually grid tie. The turbine is rated for 750 watts...it's Chinese watts, but I'd rather have a setup capable of handling 750 American/European/Australian watts just in case. The big thing, though, is I want to be able to put together and demonstrate a setup that's easy to understand and can be put together on a tight budget with stuff that's readily available on eBay or Amazon. $125 is what I can spend, if I need to spend more it's fine, but I want it to be less AND be reliable/safe. I know there's one item solutions to this out there, but they're a little pricier and I like the idea of piecing it together myself...the more I do this way the more I learn about this stuff.
