This status code indicates that the Fronius Primo GEN24 208-240 inverter has received an external shutdown command. This typically originates from an external control device, such as a ripple control receiver or utility command, or a wiring issue in the external control input.
Click steps to track your progress.
Check the status of the external control device (e.g., ripple control receiver) to ensure it is not issuing a shutdown command.
Inspect the wiring to the external control input for any damage or incorrect connections.
Ensure the external control signal is deactivated if system operation is desired.
De-energize the inverter (switch off AC and DC disconnects), wait for 5 minutes, then re-energize. If the message persists, the inverter may require service.
