Decoded

Reports self-test failure; may indicate arc detection board failure; look at arc fault detection board; do: inverter restart, inverter replacement.

What can be behind Self-test failure

Failure modes that present as the reported condition, and the tests that tell them apart.

Restart first; escalate to installer or inverter replacement if persistent.

review note: support check: partial - Restart/reset is the stated solution, but 'manual reset' clearing is implied; replace-inverter/installer escalation is stated, though clearing behavior isn't explicit.
