(you can see our other models)D) The charge controller is only suitable for regulating solar panels. Never connect another charging source to the charge regulator.  How to connect solar system with the controller: Step 1:Connect the battery to the solar charge controller firstly- plus and minus.(it will auto adapts to the battery voltage) Step 2: Connect the load to the controller secondly. (If no load, then can skip to Step 3)Step 3: Connect the solar panel to the controller finally - plus and minus. The reverse order applies when de-installing.
