F56Back-up Output Overvoltage

Name in the manufacturer's documentation (user manual): Back-up Output Overvoltage[1]

In plain words (editorial)

Overvoltage on the back-up (off-grid) output – the protection prevents damage to the loads. If it happens occasionally, the manual says it may be caused by load switching and needs no action.

When to call a service technician: If it occurs frequently, contact your dealer or GoodWe after-sales.
