AFCI Sensing Control Board
The AFCI sensing board is a discrete module that monitors DC current for high-frequency noise patterns. Component drift or hardware incompatibility in older revisions leads to 'Fault 63' errors where the sensor can no longer distinguish between actual DC arcing and standard inverter switching noise. Replacing the module with the latest hardware revision recalibrates the detection threshold.

Internal Logic Ribbon Cable Kit
Signal integrity between the DC sensing circuitry and the central processing unit is maintained via multi-pin ribbon cables. Thermal cycling can cause 'micro-fretting' at the contact points or EMI ingress if the shielding is compromised, resulting in corrupted data packets that the firmware interprets as a critical arc fault system error.

Inverter Main Power Board (PCB)
In cases where the fault is persistent across standalone operations, the analog-to-digital converters on the main PCB may be damaged. This is often the result of high-voltage transients on the DC strings that bypass the surge suppression and damage the sensitive logic gates responsible for the AFCI safety loop.
