Event number Message, cause and corrective measures
601 Grid fault
The inverter has detected an excessively high proportion of direct current in
the grid current.
Corrective measures:
1. Check the grid connection for direct current.
2. If this message is displayed frequently, contact the grid operator and
check whether the monitoring threshold on the inverter can be raised.
701 Frq. not permitted > Check parameter
The power frequency is not within the permissible range. The inverter has dis-
connected from the utility grid.
Corrective measures:
• If possible, check the power frequency and observe how often
fluctuations occur.
If fluctuations occur frequently and this message is displayed often,
contact the grid operator. The grid operator must approve changes to the
operating parameters of the inverter.
If the grid operator gives its approval, discuss any changes to the
operating parameters with the SMA Service Line.
901 PE conn. missing > Check connection
The grounding conductor is not correctly connected.
Corrective measures:
• Ensure that the grounding conductor is correctly connected (see
Section 6.3 "AC Connection", page 28).
1302 Waiting for grid voltage > Installation failure grid connection > Check
grid and fuses
The inverter has detected an error in the AC cabling. The inverter cannot con-
nect to the utility grid.
Corrective measures:
1. Ensure that the AC connection is correct (see Section 6.3 "AC
Connection", page 28).
2. Ensure that the country data set has been configured correctly. Select the
parameter Set country standard or CntrySet and check its value.
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. Select the
parameter Set country standard or CntrySet and check its value.
