Event message:
Serial el.arc in String |s0| detected by AFCI mod.
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.
Corrective measures:
Disconnect the inverter from voltage sources and secure it against being switched on again.
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).
