Activating Manual Restart
Qualified person
The following errors cause the inverter to interrupt feed-in operation:
Event number | Event message | Cause |
|---|---|---|
103 | Grid fault | Overvoltage |
203 | Grid fault | Undervoltage |
401 | Grid fault | Active islanding detection |
404 | Grid fault | Passive islanding detection |
501 | Grid fault | Overfrequency or underfrequency |
For each of the above grid faults you can configure whether the inverter is to revert to feed-in operation automatically after the fault has occurred, or whether feed-in operation should remain interrupted until it is manually reactivated.
- In the parameter group AC Side > Operation > Manual restart, set the parameter Activated to On.
- For each grid fault, set the desired option of automatic or manual restart.
Setting option | Explanation |
|---|---|
On | After the grid fault, the inverter will only start feeding into the utility grid again once feed-in operation has been activated. |
Off | After the grid fault, the inverter will automatically restart grid feed-in. |
