Event message:
Serial electric arc in string |s0| detected by AFCI module
Explanation:
The inverter has detected an electric arc in the displayed string. If "String N/A" is displayed, the string could not be uniquely assigned.
The inverter stops feeding into the utility grid.
Corrective measures:
Disconnect the inverter from all voltage sources.
Check the PV modules and the cabling in the affected string or, if the string was not displayed, in all strings for damage.
Ensure that the DC connection in the inverter is correct.
Repair or replace defective PV modules, DC cables or the DC connection in the inverter.
Start manual restart (if necessary).
