Attention:

The function of the controller is to protect against voltage over-shoot and over-loading.
2. When the battery voltage is too low, the controller stops output; after the solar panel charges, the battery returns to 12.6V.
3. 12.6V is the recovery discharge voltage.
The normal voltage for the controller is 10.7V to 13.7V. These two voltage fluctuations can be manually set.
If you encounter any issues during use, please try adjusting the floating voltage to 13.7V.
First, you need to press the MCU control button for about 3-4 seconds, and then a management interface will appear on the screen.
Next, 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's recorded data when the display screen is not flashing.
