4. Setup and Installation

Follow these steps carefully to install your solar charge controller. Incorrect wiring can damage the device and connected components.

1. Connect the Battery (Step 1): Connect the positive and negative terminals of your battery to the corresponding battery terminals on the solar charge controller. Ensure a secure connection.
2. Connect the Solar Panel (Step 2): Connect the positive and negative terminals of your solar panel to the corresponding solar panel terminals on the controller.
3. Connect the DC Load (Step 3): If you have a DC load (e.g., 12V light), connect its positive and negative terminals to the load terminals on the controller.
4. Connect USB Devices (Step 4): Use the dual USB ports to charge compatible devices.

Important: Always connect the battery first, then the solar panel. Disconnect in the reverse order (solar panel first, then battery).

5.2 Battery Type Selection

It is crucial to select the correct battery type for optimal charging and battery longevity. The controller supports:

• B1: Lead-acid batteries
• B2: Li-ion batteries
• B3: LiFePO4 / Lithium Ferro Phosphate (LFP) batteries

Refer to the controller's menu to select the appropriate battery type. Incorrect selection can lead to improper charging and damage to the battery.

5.3 Adjustable Parameters

You can adjust several parameters through the controller's interface:

• Float Voltage: The maximum voltage at which the battery is maintained after full charge.
• Discharge Reconnect Voltage: The voltage at which the load will turn back on after being disconnected due to low battery.
• Discharge Stop Voltage: The voltage at which the load will be disconnected to protect the battery from deep discharge.
• Work Mode: Set the load operation mode, including timed settings for automatic load ON/OFF after sunset.

6. Maintenance

• Regular Inspection: Periodically check all wiring connections for tightness and corrosion.
• Cleanliness: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
• Ventilation: Ensure the installation area has adequate ventilation to prevent overheating, especially around the heat sink.
• Battery Health: Monitor battery voltage and performance regularly.

7. Troubleshooting

Common Issues and Solutions:

• Controller Not Working / No Display:
  • Check battery connections. Ensure the battery is connected first and correctly polarized.
  • Verify battery voltage is within the operating range (12V or 24V).
• Battery Not Charging:
  • Ensure solar panel is connected after the battery and correctly polarized.
  • Check solar panel output voltage and current.
  • Verify the selected battery type (B1, B2, B3) matches your battery.
  • Inspect all wiring for loose connections or damage.
• Load Not Working:
  • Check load connections and ensure correct polarity.
  • Verify battery voltage is above the 'Discharge Stop Voltage' setting.
  • Check the 'Work Mode' settings to ensure the load is scheduled to be ON.
• USB Ports Not Charging:
  • Ensure the controller is powered on and the battery has sufficient charge.
  • Check the USB cable and the device being charged.
