Commissioning over the SUN2000 App
PID module parameters can be set over the SUN2000 app in the following ways:
- Connect to the SmartLogger.
- Connect to the PID module.
Connecting to the SmartLogger
Prerequisites
The app has successfully connected to the SmartLogger through Bluetooth.
NOTE: - For details about how to connect the app to the SmartLogger through Bluetooth, see the SUN2000 APP User Manual.
- This section uses the screens for SUN2000APP 2.2.00.050 and SmartLogger V200R002C20SPC119 as an example.
Context
After the app successfully connects to the SmartLogger, you can view the running information and alarms, set parameters, and send commands for all devices connected to the SmartLogger on the Monitoring screen.
Procedure
- On the app login screen, select Advanced User, enter the password, and tap Log In. The SmartLogger Home screen is displayed.Figure 4-4 SmartLogger home screen
NOTE:
- The initial password for connecting to the SmartLogger from the app as Common User, Advanced User, and Special User is 00000a. Use the initial password upon first power-on and change it immediately after login. To ensure account security, change the password periodically and keep the new password in mind. Not changing the initial password may cause password disclosure. A password left unchanged for a long period of time may be stolen or cracked. If a password is lost, devices cannot be accessed. In these cases, the user is liable for any loss caused to the PV plant.
- If you log in to the app after the SmartLogger connects to the app for the first time or the SmartLogger factory defaults are restored, the quick settings screen will be displayed. You can set basic parameters for the SmartLogger on the quick settings screen. After the setting, you can modify the parameters after choosing .
- If you do not set basic parameters for the SmartLogger on the quick settings screen, the screen is still displayed when you log in to the app next time.
- Choose . The Device Mgmt screen is displayed.
- Click
in the upper right corner of the device management screen and choose Auto Device Search, as shown in Figure 4-5.
NOTE:
- The SmartLogger can automatically detect and connect to the PID module.
- You can also click Add Devices and manually add a PID module.
- If no device is searched, check that the RS485 communications cable is properly connected and that the baud rate of the PID module is the same as the baud rate of the RS485 port on the SmartLogger.
- If a double-column transformer is used, the default RS485 address for the PID module is 199. If a dual-split transformer is used, the default RS485 addresses for the PID modules are 199 and 200. You can change the RS485 address over the SmartLogger WebUI or SUN2000 app. For details, see Changing the RS485 Address.
- Tap Monitoring on the SmartLogger home screen to access the device monitoring screen, as shown in Figure 4-6.
- Choose PID on the device monitoring screen to access the main menu screen of the PID module, as shown in Figure 4-7.
- Tap Settings to access the settings screen and set PID module running parameters, as shown in Figure 4-8.
NOTE:
- For details about how to set running parameters for the PID module, see Table 4-1 in Commissioning over the WebUI.
- Running parameters cannot be set if the PID module is in the Disconnect state.
- Set Working mode to Commissioning and set commissioning output voltage. Use a multimeter that is set to the DC position to measure the three-phase (A, B, and C) voltages of the power grid to the ground, and check whether the voltages are the same as the configured values.
If they are different, check whether the PID module is correctly grounded.
- Set Working mode to Normal.
NOTE:
- Wait 3 minutes when the PID module connects to the SmartLogger for the first time. When the running state displayed on the SmartLogger page is Running, the PID module is working properly.
- To verify the voltage between the PV terminal of the SUN2000 and ground after the PID module is used in the networked system, disconnect one PV input terminal of the SUN2000. Then use a multimeter that is set to the DC position to measure the voltage between the disconnected PV input terminal and ground. (For PV– positive offset, check whether the voltage between PV– and ground is greater than or equal to 0 V. For PV+ negative offset, check whether the voltage between PV+ and ground is equal to or less than 0 V.)

Connecting to the PID Module
Prerequisites
The app has been connected to the PID module over a Bluetooth module or a USB data cable.
NOTE: - For details about how to connect the app to the PID module, see the SUN2000 APP User Manual.
- This section uses the screens for 2.2.00.050 and SmartPID2000 V100R001C00 as an example.
The Bluetooth module used for connecting the app to the PID module must be USB-Adapter2000-B.
Context
After the app successfully connects to the PID module, set protection and feature parameters on the Settings screen, and set PID module running parameters on the Maintenance screen.
Procedure
- On the app login screen, select Advanced User, enter the password, and tap Log In. The main menu screen of the PID module is displayed, as shown in Figure 4-9.
NOTE:
- The initial password for connecting to the PID module from the app as Common User, Advanced User, and Special User is 00000a. Use the initial password upon first power-on and change it immediately after login. To ensure account security, change the password periodically and keep the new password in mind. Not changing the initial password may cause password disclosure. A password left unchanged for a long period of time may be stolen or cracked. If a password is lost, devices cannot be accessed. In these cases, the user is liable for any loss caused to the PV plant.
- If you log in to the app after the PID module connects to the app for the first time or PID module factory defaults are restored, the quick settings screen will be displayed. On the quick settings screen, you can set basic parameters for the PID module. After setting parameters, you can modify the parameters after tapping Settings on the main menu screen.
- If you do not set basic parameters for the PID module on the quick settings screen, the screen is still displayed when you log in to the app next time.
- Choose and set protection and feature parameters for the PID module, as shown in Figure 4-10 and Figure 4-11.
NOTE:
- For details about how to set running parameters for the PID module, see Table 4-1 in Commissioning over the WebUI.
- Running parameters cannot be set if the PID module is in the Disconnect state.
- Choose , set Working mode to Commissioning, and set Commissioning output voltage, as shown in Figure 4-12.
- Use a multimeter that is set to the DC position to measure the three-phase (A, B, and C) voltages of the power grid to the ground, and check whether the voltages are the same as the configured voltages.
If they are different, check whether the PID module is correctly grounded.
- Set Working mode to Normal.
NOTE:
- When the running state displayed on the working mode screen is Running, the PID module is working properly.
- To verify the voltage between the PV terminal of the SUN2000 and ground after the PID module is used in the networked system, disconnect one PV input terminal of the SUN2000.
