30/50/70A MPPT Solar Charge Controller 12/24V Panel Battery Regulator Dual USB

SAFETY INSTRUCTIONS 1. The function of the controller is to protect voltage overshoot and overplay. 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. 3. 12.6V is the recovery discharge voltage. 4. The normal voltage of the controller is 10.7V to 13.7V. These two voltage fluctuations can be set manually.

If you have trouble in use, try adjusting the float voltage to 13.7V: 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. Second, you must press the add button on the screen until the voltage reaches 13.7V. Finally, you need to press the MCU control button again, which will save the controller record data when the display does not flicker.
