Fault - 548 - 563


The output current of the PVS is obviously abnormal.


  1. Check whether the PV array is shielded. If the PV array is clear and is not shielded, check whether the PV modules are faulty.
  2. Check the DC input cable for disconnection. If so, reconnect the cable and reset the PVS function.
  3. If the fault still exists, please contact with Sungrow.
