This particular charge controller has nothing wrong with it. It was shipped by mistake to a customer that ordered a smart controller, and thus was returned. The box has been opened. We have not tested this for full functionality but have no reason to believe it’s anything less than fully functional. Enjoy a huge Savings Shack discount with free shipping included!
