https://www.harborfreight.com/100-watt-solar-panel-kit-63585.html Does anybody else have this same kit with the same charge controller in the photo? Has anybody figured out the functions of the controller? The instructions provided are incomplete. It hasn't seemed to be charging recently or not fully. There are several functions that can be programmed into the controller but it is a mystery as to what is what. Has anybody figured it out on how these will keep a maximum charge? Can the charger tell if a panel has a short?
