No power being fed in, despite closed relay

Hva betyr 305 ?

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.
