event will be reported at the latest one day after the detection of the defective string. This prevents
partial failures of the PV array from being undetected for a long time and which will result in yield
losses. The self-learning string failure detections automatically identifies if a string has been repaired
and resets the event. If the defective string should no longer be connected, the event must be reset
manually.

In accordance with the National Electrical Code
detection and interruption. The arc-fault circuit interrupter is listed in accordance with UL 1699B
Ed. 1. A detected electric arc causes the inverter to interrupt feed-in operation for a short time and
to resume the feed-in operation automatically. If the installation conditions allow it, you can
deactivate the arc-fault circuit interrupter.

Installation Manual
®
, the inverter has a system for DC arc fault
Explanation
Waiting for feed-in conditions
The conditions for feed-in operation are not yet met. As soon as the
conditions are met, the inverter will start feed-in operation.
Secure power supply operation
The secure power supply operation is enabled and the inverter sup-
plies the outlet with current from the PV system.
Update of central processing unit
The central processing unit of the inverter is being updated.
Feed-in operation
The inverter feeds in with a power of at least 90%.
Feed-in operation
The inverter is equipped with a dynamic power display via the green
LED. Depending on the power, the green LED pulses fast or slow. If
