External Shutdown
Fronius · Symo Advanced
What does 802 mean?
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.
Common Causes
- An external control signal (e.g., from a utility ripple control receiver) is active, commanding the inverter to shut down.
- A wiring issue to the external control input, such as damage or an incorrect connection, is falsely activating the shutdown command.
Repair Steps & Checklist
Click steps to track your progress.
- 1

Inspect the wiring to the external control input for any damage or incorrect connections.
- 3
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.
