10 Troubleshooting
Event number Message, cause and corrective measures
3301
Unstable operation > Generator output too low
There is not enough power at the DC input of the inverter for stable operation.
This may be caused by snow on the PV modules or insufficient irradiation. The
inverter interrupts feed-in operation and can no longer connect to the utility
grid.
Corrective measures:
3302 Unstable operation > Abort self-test
There is not enough power at the DC input of the inverter for stable operation.
This may be caused by snow on the PV modules or insufficient irradiation. The
inverter interrupts feed-in operation and can no longer connect to the utility
grid.
Corrective measures:
3303 Unstable operation > Data storage blocked
There is not enough power at the DC input of the inverter for stable operation.
This may be caused by snow on the PV modules or insufficient irradiation. The
inverter interrupts feed-in operation and can no longer connect to the utility
grid.
Corrective measures:
3401 to 3402 DC overvoltage > Disconnect generator
Overvoltage at the DC input. This can destroy the inverter.
Corrective measures:
If the DC voltage is below the maximum input voltage of the inverter,
reconnect the DC connectors to the inverter.
If the DC voltage is above the maximum input voltage of the inverter, ensure
that the PV array has been correctly rated or contact the installer of the PV
array.

1. Wait for higher irradiation.
2. If this message is displayed frequently, ensure that the PV array has been
correctly rated and wired.
1. If irradiation is too low, wait for it to increase.
2. If this message is displayed frequently, ensure that the PV array has been
correctly rated and wired.
1. Wait for higher irradiation.
2. If this message is displayed frequently, ensure that the PV array has been
correctly rated and wired.
1. Immediately disconnect the inverter from all voltage sources (see
Section 9, page 39).
2. Check whether the DC voltage is below the maximum input voltage of
the inverter.
3. If this message is repeated frequently, contact the Service.
