System Power-On

System Power-On


Before turning on the AC switch between the inverter and the power grid, check that the AC voltage is within the specified range using a multimeter.


  1. Turn on the AC switch between the inverter and the grid.

    If you perform 2 before 1, the inverter reports a fault about abnormal shutdown. The inverter can start normally after the fault is automatically cleared.

  2. Turn the DC switches at the bottom of the inverter to ON.
  3. Connect a mobile phone that runs the SUN2000 app to the inverter using a Bluetooth module, a WLAN module, or a USB data cable.

    Figure 6-1 Connection mode
    • Purchase a Bluetooth module or a WLAN module bundled with the inverter. A Bluetooth module or a WLAN module purchased from any other source may not support communication between the inverter and the SUN2000 app.
    • Use the USB data cable delivered with the mobile phone. The port type is USB 2.0.

  4. Tap the user name area to switch among Common User, Advanced User, and Special User.

    Figure 6-4 Switching the user
    • The login password is for the inverter that connects to the SUN2000 app and is used only when the inverter connects to the app.
    • When the WLAN connection is used, the initial name of the WLAN hotspot is Adapter-WLAN module SN, and the initial password is Changeme.
    • The initial passwords for Common User, Advanced User, and Special User are all 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.
    • During the login, if five consecutive invalid password entries are made (the interval between two consecutive entries is less than 2 minutes), the account will be locked for 10 minutes. The password should consist of six digits.

  5. Enter the password and tap Log In.
  6. After successful login, the quick settings screen or main menu screen is displayed.

    • If you log in to the SUN2000 app after the device connects to the app for the first time or factory defaults are restored, the quick settings screen will be displayed, on which you can set basic parameters. After the settings take effect, you can enter the main menu screen and modify the parameters on the Settings screen. If the AC switch between the inverter and the power grid is turned on but the three DC switches on the inverter are not in the ON position, Grid code is not displayed on the quick settings screen.
    • You are advised to log in to the quick settings screen as Advanced User for parameter settings.
    • Set the correct grid code based on the application area and scenario of the inverter.
    Figure 6-5 Quick settings (advanced user)
    • Set the power grid code that applies to the country or region where the PV plant is located and the inverter model.
    • Set user parameters based on the current date and time.
    • Set Baud rate, RS485 protocol, and Address based on site requirements. Baud rate can be set to 4800, 9600, or 19200. RS485 protocol can be set to MODBUS RTU, and Address can be set to any value in the range of 1 to 247.
    • When multiple inverters communicate with the SmartLogger over RS485, RS485 address for all the inverters on each RS485 route must be within the address range set on the SmartLogger and cannot be duplicate. Otherwise, the communication will fail. In addition, Baud rate of all the inverters on each RS485 route must be consistent with the SmartLogger baud rate.
