Error: 304AC F Outrange

Name in the manufacturer's documentation (user manual): AC F Outrange[1]

In plain words (editorial)

The inverter sees the grid frequency outside the allowed range and disconnects. The manual says to switch off the DC switch, check the AC wiring (especially the neutral) and the grid frequency, then restart.

When to call a service technician: If it keeps returning, the installer checks the AC wiring and the grid settings.
