Important: Always connect the battery first and disconnect the load first, then the solar panel, and finally the battery when disassembling the system.

6. Cov lus qhia ua haujlwm

The controller features an LCD display and control buttons for monitoring and adjusting settings.

6.1. Cov Vijtsam LCD

The LCD display provides real-time information about your solar system, including:

• Hnub ci vaj huam sib luag voltage thiab them nyiaj raws li txoj cai.
• Roj teeb voltage thiab theem nqi.
• Load status (on/off) and current.
• Qhov system voltage (12V lossis 24V).

6.2. Kho Voltage Chaw

The controller allows for manual adjustment of certain voltage parameters, such as the over-discharge recovery voltage. If you encounter issues or need to fine-tune your system, you can adjust the voltage:

1. Press and hold the MCU control button (usually the 'Menu' or 'Set' button) for approximately 3-4 seconds. This will bring up a management interface on the display.
2. Use the 'Add' button (or 'Up' arrow) to navigate through the settings and increase the voltage value until it reaches your desired setting, for example, 13.7V for battery recovery.
3. Press the MCU control button again to save the new setting. The display will stop flashing, indicating the data has been saved.

6.3. USB Output Usage

The dual USB ports can be used to charge various 5V devices, such as mobile phones, driving recorders, and cameras.

7. Kev tu

Regular maintenance ensures optimal performance and longevity of your solar charge controller.

• Ntxuav: Periodically clean the controller's exterior with a dry cloth to remove dust and dirt. Ensure the display remains clear.
• Kev txheeb xyuas: Annually inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can cause overheating and damage.
• Qhov cua: Ensure the installation area remains well-ventilated to prevent overheating of the controller.

8. Kev daws teeb meem

Tshooj no hais txog cov teeb meem uas feem ntau tshwm sim thiab lawv cov kev daws teeb meem.

8.1. No Output from Load Terminals

• Cov tsos mob: The load connected to the controller is not receiving power.
• Ua Tau Ua Tau: Roj teeb voltage is too low. The controller automatically stops output when battery voltage drops below a certain threshold (e.g., 10.5V-11V for a 12V system) to protect the battery from over-discharge.
• Kev daws: Allow the solar panel to charge the battery. The controller will resume load output once the battery voltage recovers to 12.6V (for a 12V system).

8.2. Tsis yog Voltage Readings or Charging Behavior

• Cov tsos mob: The display shows unexpected voltage values, or charging seems inefficient.
• Ua Tau Ua Tau: Voltage settings may be misconfigured or require adjustment. The normal operating voltage range for the controller is typically 10.7V to 13.7V (for a 12V system).
• Kev daws: Refer to Section 6.2 "Adjusting Voltage Settings" to manually adjust the voltage parameters, such as setting the recovery voltage to 13.7V if needed.
