Overcurrent (AC)

Was bedeutet 301 ?

This code indicates an overcurrent condition on the AC side of the inverter. This typically causes a short-term interruption in energy feeding, after which the inverter will attempt to resume its startup routine.

• Excessive current drawn from or fed into the AC grid, possibly due to a grid fault or short circuit.
• Internal inverter fault causing high AC current output.
• Oversized PV array relative to the inverter's AC output capability during peak production.

   If the status code is displayed continuously, notify a Fronius-trained service engineer for further diagnosis.

2. 2

   Inspect AC wiring for shorts or damage.

3. 3

   Verify that the inverter's AC output current limits are appropriate for the connected grid and cabling.
