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 power
distribution grid.
Corrective measures:
• Ensure that the country data set has been
configured correctly. Check the setting of the rotary

3301 to
3303 Unstable operation The supply at the DC input is not sufficient for stable
operation. The inverter cannot connect to the power
distribution grid.
Corrective measures:
• Ensure that the small wind turbine system is
correctly rated.
3304 Gen. output too low The small wind turbine system delivers insufficient DC
power. The inverter cannot connect to the power
distribution grid.
Corrective measures:
• Wait for stronger wind, if necessary reduce the
critical voltage to start feed-in. To do this, change
the parameter Critical voltage to start feed-in or
A.VStr.
• If this message is frequently displayed at medium
wind conditions, ensure that the small wind turbine
system is correctly rated.
