Anti-islanding function is no longer being implemented correctly

¿Qué significa 456 ?

This code indicates that the anti-islanding function, a critical safety feature that prevents the inverter from operating when disconnected from the main grid, is no longer functioning correctly. This will typically cause the inverter to disconnect from the grid.

• Malfunction of the anti-islanding detection hardware or software.
• External grid conditions preventing correct detection.
• Corruption of anti-islanding parameters.

1. 1

   If the status code is displayed continuously, notify a Fronius-trained service engineer for diagnosis of the anti-islanding circuitry.

2. 2

   Perform an AC reset by cycling the automatic circuit breaker to re-initialize the function.

3. 3

   Verify that grid parameters relevant to anti-islanding detection are correctly set.
