SMA MEDIUM VOLTAGE POWER STATION 500SC-JP - Redetecting the Sunny String-Monitors Via the Sunny Central String-Monitor Controller; Detecting the Sunny String-Monitors Via the Communication Unit; Adjusting the Identification of the Sunny String-Monitors

Procedure:
1. Log into the user interface (see Section12.8.1, page177).
2. Select the tab Parameters.
3. Set the parameter DevFunc to AutoDetect_SSMU.
4. Select the button [Save].
5. Select the tab Instantaneous values.
6. Select SSMUNoOf and check the number of detected Sunny String-Monitors.
Once all Sunny String-Monitors have been detected, detect them via the communication unit(see
Section6.5.11.5, page89).
If only some of the SunnyString‑Monitors have been detected, use SunnyCentralString‑MonitorController to
redetect them (see Section6.5.11.4, page89).
6.5.11.4 Redetecting the SunnyString-Monitors via the SunnyCentralString-
MonitorController
1. Log into the user interface (see Section12.8.1, page177).
2. Select the tab Parameters.
3. Set the parameter DevFunc to Retry.
4. Select the button [Save].
5. Select the tab Instantaneous values.
6. Select SSMUNoOf and check the number of detected Sunny String-Monitors.
Once all Sunny String-Monitors have been detected, detect them via the communication unit(see
Section6.5.11.5, page89).
If only some of the SunnyString-Monitors have been detected, contact the Service .
6.5.11.5 Detecting the Sunny String-Monitors via the Communication Unit
1. Log into the user interface (see Section12.8.1, page177).
2. Select Data > Detection.
3. In the field Total number of devices to be detected, enter the number of Sunny String-Monitors +2.
4. Select the button [Start detection].
☑ The communication unit starts detecting all inverters and displays its progress. Once all devices have been
detected, the message ### Device detection finished ### is displayed.
☑ The Sunny String-Monitors have been detected.
6.5.11.6 Adjusting the Identification of the Sunny String-Monitors
1. Log into the user interface (see Section12.8.1, page177).
2. Select the first Sunny String-Monitor from the device list.
3. Select the tab Parameters.
4. Select the parameter SSMId and allocate a unique identification number to the SunnyString-Monitor. Note the
identification number.
5. Adjust the identification of the remaining Sunny String-Monitors using the same process.
