I have (2) 80 watt panels feeding (3) 12 volt batteries in parallel. I use the charge controller to keep things in order. I have (3) 7 watt CF lights in various rooms that light the whole area at night (plus reading lights). We call it emergency lighting. The controller has done an excellent (trouble free) job of keeping things in line. It has shut down a few times on low battery voltage and limited batter 'over voltage' many times...Just as it was designed to do. After 14 months, an excellent product for my use.
