Review on Xantrex C40 Charge Controller by Bill Snyder

I've been looking for the right controller for a long time and here it is. It's a simple but smart and robust system rather than fancy packaging at a great price. I am using this for my home solar system, am continuing to research other controllers and will be purchasing another Xantrex for my RV system. This controller has been monitoring and maintaining my system since August 2013. I had to contact support about something I didn't understand and I was pleased with the quick response, courtesy and understanding of my question.
