- Huawei devices can be automatically detected or manually added. The EMI, power meter, slave SmartLogger, and third-party devices cannot be automatically detected. You need to add them manually.
- Before manually adding an EMI connected over the COM port, set RS485 parameters correctly by following the instructions in Setting RS485 Parameters. When adding an EMI, set Device Type to EMI. After adding an EMI manually, correctly set the EMI parameters. For details, see Setting EMI Parameters.
- Before manually adding the Modbus or DL/T645 power meter, set RS485 parameters correctly by following the instructions in Setting RS485 Parameters. Before manually adding the Modbus power meter, correctly set the power meter parameters. For details, see Setting Power Meter Parameters. When adding a power meter, set Device Type to Power Meter and Comm.protocal to the protocol supported by the power meter.
- When manually adding a slave SmartLogger, correctly set Modbus TCP parameters. Set Link setting to Enable, and set the client IP address to the IP address for the slave SmartLogger. For details, see Setting Modbus TCP Parameters. When adding a slave SmartLogger, set Device Type to SmartLogger and set IP Address to the IP address of the slave SmartLogger.
- When connecting a third-party device, you need to import a configuration file for the device and then manually add the device.
- An accessed device can be removed manually, and a removed device can be added again.
- Auto Assign Address allows you to adjust device addresses based on serial numbers. If a device cannot access due to address conflict, perform this operation to assign a new device address and then access the device.
- After a device is connected, you can export the configurations for the device. If you need to change the name of the exported file, retain the extension .cfg. Otherwise, the file will be unavailable.
- You can click the Start, Stop, or Reset icon to send the corresponding command to all SUN2000s connected to the SmartLogger. The login password is required if you need to send a command.
Device List
Because of permission restriction, log in as Advanced User or Special User. Choose to access the target page.
You can modify the device name and address on the WebUI, or export a device information file in CSV format and import the CSV file into the WebUI after modification.
Exporting Parameters
Because of permission restriction, log in as Advanced User or Special User. Choose to access the target page.
You can export configuration parameters of multiple inverters to a .csv file. Site engineers can then check whether the inverter configurations are correct in the exported file.
Clearing Alarms
If you need to clear the active and historical alarms of certain or all devices connecting to the SmartLogger, and re-collect alarm data, perform this operation.
Because of permission restriction, log in as Advanced User or Special User. Choose to access the target page.
- By clearing alarms, users can clear all active and historical alarms for the selected device and enable the SmartLogger to re-collect alarm data.
- By clearing alarms, users can clear the local SmartLogger alarms or device storage alarms. If the version of the SUN2000-(8KTL-28KTL) is earlier than SUN2000 V100R001C81, users can only clear local SmartLogger alarms by performing the operation.
- If Clear Alarm is performed for the Huawei devices such as the inverter and PID, Alarm Reset must be performed on the NMS. Otherwise the SmartLogger cannot collect alarm data from the devices after alarms are cleared.
- If Clear Alarm is performed for the SmartLogger, Alarm Reset must be performed on the NMS. Otherwise the SmartLogger cannot collect alarm data from the devices after Alarm Reset is performed.
Data Recollection
Users can recollect previous performance data and energy yield over the WebUI. The recollection results can be queried on the Monitoring page.
- This function is not supported by the SUN2000-(8KTL-28KTL).
- When you perform data recollection and query the performance data of the inverter after the SUN2000-33KTL/40KTL software is upgrades from SUN2000 V200R001C00SPCXXX to SUN2000 V200R001C90SPCXXX, the current-day energy yield generated before the upgrade cannot be queried.
Because of permission restriction, log in as Advanced User or Special User. Choose to access the page.
- Select the data recollection type and the corresponding recollection period.
- Select the inverter whose data needs to be recollected.
- Click Collect Data.
- Click different tabs to view the data recollection progress and status. Data is recollected in the sequence of performance data, daily energy yield, monthly energy yield, and annual energy yield.
