Drake, My 2 cents: After getting over my many years boycott of Schneider due to the legacy of Xantrex, I finally tried the new XW several years ago, and haven't really looked back since. They certainly have had their hiccups, and there is a fair amount of complexity to the programming depending on what you are trying to do, but they are solid both electrically and programmatically from my experience. I also have so far enjoyed using Sol-Ark from my limited experience, although I have yet to use it in an off-grid environment. Howie
