Decoded

Reports DC bus overvoltage; look at inverter choke inductor; confirm with DC voltage measurement; do: wiring and terminal check, inverter restart, inverter replacement.

What can be behind DC bus overvoltage

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