Event message:

  • Error in the rapid shutdown system

Explanation:

This message can have the following causes:

  • The rapid shutdown function was not correctly configured.

  • The PV module could not be correctly disconnected. Voltage can be applied to the DC inputs of the inverter.

  • The standby voltage of all PV module switches of a string is > 30 V.

  • With DC lines laid in parallel, another inverter in the system has caused the Sunspec signal to be overwritten.

Corrective measures:

  • Check the settings 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 module switches.

  • Check the standby voltage of the PV module switches used and ensure that the standby voltage of all PV module switches of a string < 30 V.
