Message, cause and corrective measures
Electr. arc detected > Please confirm by tapping
The inverter has detected an electric arc and was recommissioned after a dis-
connection. By tapping, you are confirming that you have repaired any possi-
ble damage to PV modules, DC conductors or plugs in the PV system.
Corrective measures:
• Tap on the enclosure lid of the Connection Unit within ten seconds of the
message appearing in order to recommission the inverter.
Self-diagnosis > Input C defective
The cause must be determined by the Service.
Corrective measures:
• Contact the Service (see Section 11 "Contact", page 67).

Communication to the system control absent. Depending on the fall-back set-
ting, either the last received values will be retained or the active power will be
limited to the set percentage value of the inverter nominal power.
Corrective measures:
• Ensure that the connection to the system manager (e.g.
Sunny Home Manager) is intact and that no cables are damaged or that
no plugs have been pulled.
