3. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Please follow the connection sequence carefully:
- Connect the Battery: First, connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage.
- Connect the Solar Panel: Next, connect the solar panel to the charge controller. Again, observe correct polarity.
- Connect the Load: Finally, connect your DC load to the charge controller.
Important: When disconnecting the system, reverse the order: Disconnect the Solar Panel, then the Load, and finally the Battery.
Ensure that the wire size is appropriate for your system. Refer to the table below for recommended terminal sizes based on controller model:
| Controller Model | Terminals (mm²/AWG) |
|---|---|
| 1024AU | 4mm²/12AWG |
| 2024AU | 10mm²/8AWG |
| 3024/3048AU | 16mm²/6AWG |
| 402/4048AU | 16mm²/6AWG |
| 6024/6048AU | 25mm²/4AWG |

4. Operating Instructions
The LCD display and buttons allow for easy monitoring and parameter setting:
- Navigating the Display: Use the 'MENU' button to cycle through different display interfaces, showing battery voltage, charging current, load status, and other system parameters.
- Setting Battery Type: To set the battery type (Sealed, Gel, or Flooded), press and hold the 'SET' button for 5 seconds. Use the 'MENU' button to select the desired type, then press 'SET' again to confirm or wait 5 seconds for automatic confirmation.
- Load Control Modes: The controller supports various load modes. To enter the load mode setting interface, press and hold the 'SET' button until the number begins flashing. Use the 'MENU' button to adjust the parameter, then press 'SET' to confirm. Available modes include:
- Light ON/OFF: Load is on for 1 hour after sunset.
- Load is on for X hours after sunset (e.g., 2 hours, 3 hours).
- Load is on for X hours before sunrise (e.g., 13 hours, 14 hours).
- Test mode: Load is always on.
- Manual mode: Load can be manually turned ON/OFF by pressing the 'SET' button.
- USB Charging: The dual USB ports provide 5V/2.4A (total) output for charging mobile phones, tablets, and other USB-powered devices.

5. Maintenance
To ensure optimal performance and longevity of your EPEVER Solar Charge Controller, regular maintenance is recommended:
- Clean the Controller: Periodically wipe the controller's exterior with a dry cloth to remove dust and debris. Ensure the heat sink fins are clear of obstructions for proper cooling.
- Check Connections: Regularly inspect all wiring connections (battery, solar panel, load) to ensure they are tight and free from corrosion. Loose connections can lead to voltage drops and overheating.
- Monitor Performance: Utilize the LCD display to regularly check system parameters such as battery voltage, charging current, and load status. Any significant deviations may indicate an issue.
- Environmental Conditions: Ensure the controller is installed in a well-ventilated area, away from direct sunlight, moisture, and corrosive gases. Maintain the operating temperature within the specified range (-25 to 55 ℃).
