• The standby voltage of all PV array disconnect switches of a string is >
30V.
Corrective measures:
• Check the configuration of the Rapid Shutdown function and ensure that
the operating mode selected is selected according to the DC
disconnection unit used.
• Check the functionality of the PV array disconnect switches.
• Check the standby voltage of the PV array disconnect switches used and
ensure that the standby voltage of all PV array disconnect switches of a
string < 30V.
