Event number Message, cause and corrective measures
1302 Waiting for grid voltage > Installation failure grid connection > Check
grid and fuses
L or N not connected.
Corrective measures:
• Ensure that L and N are connected.
• Make sure that the circuit breaker is switched on.
• Ensure that the AC cable is not damaged and that it is connected
correctly.
1501 Reconnection fault grid
The changed country data set or the value of a parameter you have set does
not correspond to the local requirements. The inverter cannot connect to the
utility grid.
Corrective measures:
• Ensure that the country data set has been configured correctly. To do this,
select the parameter Set country standard and check the value.
3301 to 3303 Unstable operation
There is not enough power at the DC input of the inverter for stable operation.
The inverter cannot connect to the utility grid.
Corrective measures:
• Ensure that the PV array is designed correctly.
• Ensure that the PV array is not covered by snow or otherwise shaded.
• Ensure that the PV array is free of errors.
3401 DC overvoltage > Disconnect generator
Overvoltage at the DC input. This can destroy the inverter.
This message is signalized additionally by rapid flashing of the LEDs.
Corrective measures:
• Immediately disconnect the inverter from all voltage sources (see
Section 2.1, page 5).
• Check whether the DC voltage is below the maximum input voltage of
the inverter. If the DC voltage is below the maximum input voltage of the
inverter, reconnect the DC connectors to the inverter.
• If the DC voltage exceeds the maximum input voltage of the inverter,
ensure that the PV array has been correctly rated or contact the installer
of the PV array.
• If this message is repeated frequently, contact the Service (see
Section 11 "Contact", page 33).
