Hey solar people, Yesterday I gave the URL of the Solar Supplier in Ukiah, CA that I once used. Well, after playing a bit on their site, I find they are not the same as they used to be. I cannot find any info on Marine or RV. I think it's the same people, but maybe they are after the bigger sales now. I Googled and tried a few places then found Wholesale Solar http://www.wholesalesolar.com/ And in particular a page of PDF's that should be enough to help us get smart about solar power http://www.wholesalesolar.com/information.html And they have a special section for Mobile (RV-Marine) applications. Sorry for the bad link. This one appears to be pretty useful. I began looking because I was curious about the AGM batteries and the controller requirements. I figured since the AGM batteries require a special charger, the controller would be also. It's all there. Bill I'm really leaving town this time.
