No power being fed in, despite closed relay

What does 305 mean?

This code indicates that the inverter's internal relay is closed, but no power is being fed into the grid. This suggests a potential issue in the power path even though the switching element is engaged, causing a short-term interruption before the inverter attempts to restart.

• Failure or malfunction of internal power stage components despite relay closure.
• Grid impedance issues preventing power injection.
• Faulty internal measurement or control circuitry preventing detection of power flow.

1. 1

   If this status code keeps recurring, contact your system engineer for diagnosis.

2. 2

   Perform an AC reset by cycling the automatic circuit breaker to potentially clear transient relay issues.

3. 3

   Verify the AC grid voltage and frequency are within the permissible operating range.
