W3Grid Phase Wrong

Name in the manufacturer's documentation (fault list): Grid Phase Wrong[1]

In plain words (editorial)

The inverter sees the grid phases connected in the wrong order. The manual says to check the phase sequence, try changing the grid type setting and then check the wiring at the grid end.

When to call a service technician: Phase wiring is corrected by the installer or an electrician.
