Fault codes › SMA › Sunny Highpower PEAK3 (SHP 125-172-US)
Reports internal device fault; look at inverter bridge, grid tie relay; confirm with grid voltage measurement; do: inverter restart, inverter replacement.
Failure modes that present as the reported condition, and the tests that tell them apart.

Applies when the event is frequent or permanent: disconnect and recommission; replace the inverter if it persists.
