Do I need a Temperature Sensor? Maybe, but maybe not. If your batteries are at a different temperature than your controller (more than 10 degrees F - Morningstar recommends 5 degrees), then yes you probably should. For instance, if your controller is inside but your batteries are outside in the weather, the built-in temperature compensation would not be correct.
