Overvoltage at DC input. The inverter may be damaged.
Corrective measures
Immediately disconnect the inverter from the grid!
1. Turn off the line circuit breaker.
2. Remove the Electronic Solar Switch.
3. Disconnect all the DC plug connectors.
4. Check DC voltage:
– If the DC voltage exceeds the maximum input voltage, check the
plant design or contact the person who installed the PV
generator.
– If the DC voltage is under the maximum input voltage, reconnect
the inverter to the PV generator as described in section
5.5.4”Connecting the PV Generator (DC)” (page36).
If the message occurs again, disconnect the inverter again and contact
the SMA Serviceline (see section 13”Contact” (page90)).
