            What is the difference between this item and the Model # CTRL-RVRPG20? I see this is negative ground, while the other is positive ground and cheaper. Why care about the ground?

            Answer This Question

            Hello, Positive ground refers to the terminals of the charge controller and how they are bonded together. You may use a positive ground charge controller in the same way a negative ground controller is used except for grounding the charge controller or connecting any loads with a negative ground. Please contact us if you have any other questions, have a wonderful day.
