Voltage increase protectionParameter for setting the 10-minute average for the rise-in voltage protection (applies only to Germany)In Germany, inverters are permitted to feed into the public grid with up to 260 V AC. However, the DIN VDE 0126-1-1 standard stipulates that the 10-minute AC voltage average may not exceed 253 V. If the average over 10 minutes exceeds the threshold value of 253 V, the inverter disconnects itself from the grid. As soon as the 10-minute average decreases back to less than 253 V, the inverter will continue to feed power into the grid.

3.3 Event MessagesEvent messages smaller than 100 correspond to the error number displayed in the inverter display.No. Display text Description1 Grid fault The grid voltage has exceeded the permissible range. For

safety reasons, the inverter disconnects itself from the grid. Cause:

• The grid voltage at the point of connection of the inverter is too high.

• Grid impedance at the connection point of the inverter is too high.

Corrective measures:• Check the grid voltage and connection on the

inverter.If the grid voltage lies outside the acceptable range because of local grid conditions, ask the utility provider if the voltage can be adjusted at the feed-in point or if it would agree to changes in the values of the monitored operational limits.If the grid voltage lies within the tolerance range, yet this error is still being displayed, contact the SMA Serviceline.

101 Grid overvoltage (spot value)

Spot value for the grid voltage measurement with reasonable elimination of outliers exceeds a preset maximum value.

102 Grid overvoltage fast The effective value of the grid voltage has exceeded the upper maximum grid voltage level for the set triggering time.

103 Grid overvoltage slow The effective value of the grid voltage has exceeded the lower maximum grid voltage level for the set triggering time.



2 Grid fault The grid voltage has fallen below the permissible range. For safety reasons, the inverter disconnects itself from the grid.Cause:

• Grid disconnected.• AC cable damaged.• The grid voltage at the point of connection of the

inverter is too low.Corrective measures:

• Check for tripping of the line circuit breaker.• Check the grid voltage and connection on the

inverter.If the grid voltage lies outside the acceptable range because of local grid conditions, ask the utility provider if the voltage can be adjusted at the feed-in point or if it would agree to changes in the values of the monitored operational limits.If the grid voltage lies within the tolerance range, yet this error is still being displayed, contact the SMA Serviceline.

202 Grid undervoltage fast The effective value of the grid voltage has fallen below the lower minimum grid voltage level for the set triggering time.

203 Grid undervoltage slow The effective value of the grid voltage has fallen below the upper minimum grid voltage level for the set triggering time.

205 PLL outside limits PLL is under 140 V for 30 ms.

No. Display text Description



3 Grid fault The average grid voltage over 10 minutes is no longer within the permissible range. The inverter disconnects to assure compliance with the voltage quality of the grid. Cause:

• The grid voltage at the point of connection of the inverter is too high.

• Grid impedance at the connection point of the inverter is too high.

Corrective measures:• Check the grid voltage at the point of connection of

the inverter:If, due to local grid conditions, the grid voltage exceeds the configured limiting value, ask the utility provider whether the voltage can be adjusted at the feed-in point, or whether it would agree to a modification of the limiting value for voltage quality monitoring.If the grid voltage is continually within the acceptable range, and this error is still displayed, contact the SMA Serviceline.

301 Voltage increase protection The effective value of the grid voltage is above the permitted threshold for a specified period of time (country parameters, e.g., 10 minutes).

4 Grid fault The internal inverter monitoring has detected an impermissibly high proportion of direct current in the grid current.Corrective measures:

• Check the grid connection for direct current.If this is a recurrent phenomenon, check with the utility provider whether it is possible to raise the limiting value of monitoring.

401 Island grid The average grid frequency is outside the specified limit for a defined period of time.

404 Frequency change not permitted

Detection of excessive frequency change per second for grid operation (island grid detected).




5 Grid fault The grid frequency is not within the permissible range. For safety reasons, the inverter disconnects itself from the grid.Corrective measures:

• If possible, check the grid frequency and observe how often major deviations occur.

If repeated frequency variations occur and as a result this error occurs, ask the utility provider if it would agree to modify the operating parameters.Discuss the proposed parameters with the SMA Serviceline.

501 Grid frequency disturbance The average grid frequency is outside the specified limit for a defined period of time.

6 Grid fault The internal inverter monitoring has detected an impermissibly high proportion of direct current in the grid current.Corrective measures:

• Check the grid connection for direct current.If the event arises frequently, ask the grid operator if the operating parameters can be changed.Discuss the proposed parameters with the SMA Serviceline.

601 DC grid feed-in The DC content in the grid current exceeds a defined limit. The grid current average is compared to the limit value.

7 Frequency not permitted The grid frequency has left the allowable range. For safety reasons, the inverter disconnects itself from the grid. Corrective measures:

• Check the grid frequency and observe how often major deviations occur.

If repeated frequency variations occur and as a result this error occurs, ask the utility provider if it would agree to modify the operating parameters.Discuss the proposed parameters with the SMA Serviceline.

701 Grid frequency not permitted The grid frequency measurement indicates too much deviation from the nominal value. PLL output outside the country parameter limits.

3401 Overvoltage input A (SW) The input voltage at string A exceeds the set maximum.35 Insulation resistance The inverter has detected a ground fault in the PV generator.

Corrective measures:• Check strings for ground faults • The installer of the PV generator must remedy the

ground faults before you re-connect the affected string.

3501 Insulation failure The measured value of the active RISO measurement is below a specified limit. For safety reasons, the inverter disconnects itself from the grid.

3502 Ground fault detected Ground fault detected3503 Overcurrent Ground fuse Too much current at the SMA Plug-in Grounding38 DC overcurrent An overcurrent condition occurs on the DC side of the

inverter and it switches off.Corrective measures:

• If this event recurs frequently, check the PV generator design and connection.

3801 Overcurrent input A (SW) The measured input current exceeds the specified maximum. Spot value with reasonable elimination of outliers is above the threshold of 20 A.




39 Waiting for DC start conditions
