Great link Matt, thanks.  As for the Anderson Power Connectors, the easiest
to use online ordering for these itmes that I have found is here:

I'd looked at the Anderson Powerpole connectors online at several sites but
was always a little confused about them, the Arizona Wind & Sun site made
understanding of the product much better and ordering very easy compared to
other places.
