Possible cause
•
PV field overvoltage (lightning, electric discharge).
•
Wrong PV field dimensioning causing overvoltage.
•
Fault in the digital input detecting PV field isolation loss (see parameter
C803
in section
Solution
1. Power off the inverter immediately.
2. Try to assess the cause of the PV isolation loss fault
3. Restore the SPD by replacing its cartridges.
4. Reset the alarm: send a
