These fins are designed to dissipate heat generated during operation, ensuring the controller maintains optimal temperature and performance.

4. Setup and Installation

4.1 Mounting the Controller

• Choose a dry, well-ventilated location, protected from direct sunlight and moisture.
• Mount the controller vertically on a non-flammable surface to allow for proper heat dissipation.
• Ensure there is sufficient clearance around the controller for air circulation.

4.2 Wiring Connections

Follow the connection order strictly to prevent damage to the controller or system components. Use appropriate wire gauges for your system's current and distance.

1. Connect the Battery: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. The controller will automatically detect the system voltage (12V or 24V).
2. Connect the Solar Panel: Connect the positive and negative terminals of the solar panel(s) to the corresponding solar input terminals on the controller.
3. Connect the DC Load (Optional): Connect the positive and negative terminals of your DC load to the corresponding load terminals on the controller.

Important: Ensure correct polarity for all connections. Reverse polarity can cause permanent damage.

5. Operating Instructions

5.1 LED Display

The LED screen provides real-time information about your solar system:

• INPUT: Displays the voltage and current from the solar panel.
• BATTERY: Shows the battery voltage and charging current.
• OUTPUT: Indicates the load voltage and current.

5.2 Button Functions

• MENU Button: Press to cycle through different display parameters or enter settings mode.
• POWER Button: Press to turn the DC load output ON/OFF. Long press may enter or exit certain settings.

5.3 USB Output

The four 5V 2A USB ports can be used to charge compatible electronic devices. These ports are active when the controller is powered and the battery has sufficient charge.

6. Maintenance

• Regular Inspection: Periodically check all wiring connections for tightness and corrosion.
• Cleaning: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
• Ventilation: Ensure that the ventilation openings and heat sink fins are not obstructed.
• Battery Check: Regularly check the battery's state of charge and electrolyte level (for flooded batteries).
