Inverter in Standby state — Power feed interrupted due to safety device

What does Standby state mean?

The inverter has switched to a standby state, meaning it is no longer feeding power into the grid and is disconnected from the AC relay. This occurs when a safety device or monitoring function, such as rapid shutdown, WSD, RCMU, insulation monitoring, or AFCI, has been triggered.

• Activation of the Rapid shutdown function.
• WSD (wired shutdown) system has been triggered.
• RCMU (Residual Current Monitoring Unit) has detected a fault.
• Insulation monitoring has identified a fault in the PV system.
• AFCI (Arc Fault Circuit Interrupter) has detected an arc fault.

Click steps to track your progress.

1. 1

   Identify which specific safety device or monitoring function has been triggered (check system logs or inverter display if available).

2. 2

   Inspect the PV system for any faults related to rapid shutdown, WSD, RCMU, or insulation issues.

3. 3

   If an arc fault was detected, follow the troubleshooting steps for 'Arc detected' to resolve the DC installation issue.

4. 4

   Ensure all system components are functioning correctly and that safety standards are being met.

5. 5

   After resolving the underlying cause, the inverter may automatically resume operation, or a manual restart might be needed.
