The function of controller is to protect voltage overshoot and overplay._x000D_ 2. When the battery voltage is too low, the controller stops the output; after the solar panel is charged, the cell recovers to 12.6V._x000D_ 3. 12.6V is the recovery discharge voltage._x000D_ 4. The normal voltage of the controller is 10.7V to 13.7V. These two voltage fluctuations can be set manually._x000D_ If you have trouble in use, try adjusting the float voltage to 13.7V:_x000D_ First, you need to press the MCU control button for about 3-4 seconds, and then there will be a management interface on the screen._x000D_ Second, you must press the add button on the screen until the voltage reaches 13.7V._x000D_ Finally, you need to press the MCU control button again, which will save the controller record data when the display does not flicker._x000D_ _x000D_ _x000D_ _x000D_ Package List: _x000D_ _x000D_ 1 * SolarChargeController_x000D_ 1 * User Manual_x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
