This status code is displayed every day when the internal arc detector has been manually switched off, for example, if an external arc monitoring system is in use. This is not an error.
Click steps to track your progress.
Confirm the status code by pressing the "Enter" key on the inverter display.
Verify that the arc detector was intentionally switched off (e.g., if you have an external arc monitoring system).
If the arc detector needs to be reactivated, consult your system installer or the inverter setup menu.
