Mike, Would you be interested in a simple reverse polarity fet circuit, which would replace the "honkin' diodes" with a much lower loss?
http://www.elecdesign.com/Articles/Index.cfm?AD=1&ArticleID=9945 I also like and use the Xantrex products... cheers, skipp ps: Here's a neat little single transistor battery charging circuit. http://www.elecdesign.com/Article/ArticleID/1823/1823.html > "Mike Perryman" <[EMAIL PROTECTED]> wrote: > Lee, > Later in this thread the WestMountain charge controller is referenced... > but..
