• CC Potentiometer: Adjusts the constant current limit.
• CV Potentiometer: Adjusts the constant voltage output.
• LED Indicator: Provides visual feedback on the module's status (e.g., charging, full).

5. Installation and Wiring

5.1 Mounting

The module can be installed using four 3mm screws. Ensure adequate ventilation around the module for proper heat dissipation.

5.2 Wiring Instructions

Connect wires to the terminal blocks. 'IN' refers to the input, and 'OUT' refers to the output.

1. Connect your solar panel or input power source to the IN+ and IN- terminals.
2. Connect your battery or load to the OUT+ and OUT- terminals.

5.3 Important Safety Notes

• Reverse Connection Protection: This module does not have built-in input reverse connection protection. If connecting to a battery or power source that could be reversed, an external diode must be added in series with the input to prevent damage to the module.
• Output Anti-Backflow: The module does not have output anti-backflow protection. When connecting the output to a battery, ensure an anti-reverse diode is installed between the module's output and the battery to prevent current from flowing back into the module, which could cause damage.
• Current Detection: The module uses low-end current detection. Do not directly short the input negative terminal (IN-) and the output negative terminal (OUT-).

6. Operation

The module features three potentiometers for adjustment: MPPT voltage, constant current (CC), and constant voltage (CV). These are multi-turn potentiometers, requiring multiple rotations to observe significant changes.

6.1 Setting MPPT Voltage

The MPPT potentiometer adjusts the voltage at which the module extracts maximum power from the solar panel. This should typically be set slightly below the solar panel's open-circuit voltage under load conditions.

1. Connect the solar panel to the input (IN) terminals.
2. Connect a voltmeter to the input terminals.
3. Adjust the MPPT potentiometer until the input voltage stabilizes at the desired MPPT voltage for your solar panel.

6.2 Setting Output Constant Voltage (CV)

The CV potentiometer sets the maximum output voltage. This is crucial for charging batteries to their correct voltage level.

1. Connect the input power source (solar panel or other).
2. Disconnect any load or battery from the output terminals.
3. Connect a voltmeter to the output (OUT) terminals.
4. Adjust the CV potentiometer clockwise to increase voltage or counter-clockwise to decrease it, until the desired output voltage is reached.

6.3 Setting Output Constant Current (CC)

The CC potentiometer sets the maximum output current. This protects the battery from overcurrent during charging and the load from excessive current draw.

1. First, set the CV (constant voltage) as described above.
2. Connect an ammeter in series with the output, or connect a suitable load that will draw current.
3. Adjust the CC potentiometer clockwise to increase the current limit or counter-clockwise to decrease it, until the desired maximum output current is reached.

7. Maintenance

The FTVOGUE 5A Charging Module requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:

• Keep Clean: Periodically clean the module to prevent dust and debris buildup, especially on the heatsink, which can impede cooling. Use a soft, dry cloth.
• Check Connections: Regularly inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
• Environmental Conditions: Ensure the module operates within its specified temperature range (-40°C to +85°C) and avoid exposure to excessive moisture or direct sunlight without proper enclosure.

8. Troubleshooting

If you encounter issues with your FTVOGUE 5A Charging Module, consider the following troubleshooting steps:

• No Output Voltage/Current:
  • Verify input voltage is within the 6-36V range.
  • Check all wiring connections for proper polarity and secure contact.
  • Ensure the CV (constant voltage) potentiometer is adjusted to a voltage higher than the load's requirement or battery's current voltage.
  • Confirm the CC (constant current) potentiometer is not set too low.
• Module Overheating:
  • Ensure adequate ventilation around the module.
  • Reduce the load if it exceeds the module's 5A capacity.
  • Check for short circuits in the output wiring or load.
• Incorrect Voltage/Current Readings:
  • Recalibrate the CV and CC potentiometers carefully using a reliable multimeter.
  • Ensure your measurement tools are accurate.
• Battery Not Charging:
  • Verify the MPPT voltage is correctly set for your solar panel.
  • Check that the output voltage (CV) is set appropriately for your battery type.
  • Ensure the constant current (CC) is set to a suitable charging current for your battery.
  • Confirm the presence and correct installation of external anti-reverse diodes if used.
