F46Grid Phase Sequence Failure

Name in the manufacturer's documentation (user manual): Grid Phase Sequence Failure[1]

In plain words (editorial)

The inverter is not wired to the grid in positive phase sequence. Once the wiring is corrected (for example by swapping two live wires), the fault disappears automatically.

When to call a service technician: Have your installer or electrician correct the wiring; if the wiring is correct and the fault persists, contact GoodWe after-sales.
