GOTOTOP Boost MPPT Solar Charge Controller 24V 36V 48V 60V 72V 1200W Solar Panel Regulator with LCD Display Cooling Fan for Lithium Ion Gel Flooded Batteries

How to use 1. Press the SET key during normal operation. 2. 2. The user can press the + or - key to increase or decrease the voltage setting value as needed. Each press will change 0.1V, press and hold the key for quick continuous adjustment. 3. 3. After adjusting to the desired voltage setting value, press the OK key to confirm. Only then will the final voltage setting value be memorized and the controller will display successful setting. 4. After 4 seconds of successful setting, the controller exits the voltage setting display interface. 5. In the “Voltage Setting” display interface, if there is no operation within 4 seconds after the last pressing of the + or - key and OK key, the controller will automatically exit the “Voltage Setting” display interface and the adjusted “Voltage Setting Value” will not be memorized.
