App Login

App Login

Prerequisites

  • The DC or AC side of the solar inverter has been energized.
  • Connection over a WLAN module or a Bluetooth module:
    1. The WLAN module or Bluetooth module is connected to the USB port at the bottom of the solar inverter.
    2. The WLAN or Bluetooth function is enabled.
    3. Keep the mobile phone within 5 m from the solar inverter. Otherwise, the communication between them would be affected.
  • Connection over a USB cable:
    1. The USB data cable is connected from the USB port at the bottom of the solar inverter to the USB port on the mobile phone.
    2. The USB data cable has been successfully connected and Connected to USB Accessory is displayed on the screen. Otherwise, the connection is invalid.

Procedure

  1. Start the app. The login screen is displayed. Select Connection Mode to connect to the solar inverter.

    • When the WLAN connection is used, the initial name of the WLAN network is Adapter-WLAN module SN, and the initial password is Changeme. 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.
    • When the Bluetooth connection is used, the name of the connected Bluetooth device is the last eight digits of the SN bar code+HWAPP.
    • When the USB connection is used, after you select Use by default for this USB accessory, the message prompting you to confirm that the app is allowed to access the USB device will not appear if you log in to the app again without removing the USB data cable.

  2. Select a login user and enter the password.

    • The login password is the same as that for the solar inverter connected to the app and is used only when the solar inverter connects to the app.
    • The initial passwords for Common User, Advanced User, and Special User are both 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 characters.

  3. After successful login, the quick settings 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. If you do not set the basic parameters for the solar inverter on the Quick Settings screen, the screen is still displayed when you log in next time.
    • To set the basic parameters on the Quick Settings screen, switch to Advanced User. When you log in as Common User or Special User, enter the password of Advanced User in the dialog box that is displayed. After you confirm the password, go to the Quick Settings screen.
