    Question

    How do I wire the SofarSolar ARPC to a Sofar inverter?

    Answer

    To connect the SofarSolar ARPC to your inverter for zero-export functionality, follow these general wiring guidelines based on the system diagram:

    • Derating Signal Connection: The ARPC communicates with the inverter via a control cable. Connect the 'Derating Signal' output terminals on the ARPC to the corresponding communication or power control ports on the Sofar inverter.
    • Current Sensor (CT) Wiring: Install the split-core current sensor on the live wire between the Import/Export meter and the Grid. The output from this sensor must be wired back to the 'Measuring Current Inputs' on the ARPC.
    • Voltage Sensing: The ARPC requires a voltage reference. Connect the L1-N (and L2, L3 for three-phase systems) to the AC bus to allow the device to measure grid voltage.
    • Power Supply: Ensure the ARPC is powered by a 230VAC supply as per the specifications.

    Note: Always ensure the inverter's RS485 or power control settings are configured to recognize the external controller. Because specific terminal numbering can vary by inverter model, please refer to your specific Sofar inverter manual to identify the exact pins for the derating/control signal.
