  1. Obtain the software upgrade package from the technical support website.
  2. Decompress the upgrade package.

    • When the login password of the SUN2000 app is the initial password (00000a), there is no need to perform 35.
    • When the login password of the SUN2000 app is not the initial password, perform 37.

  3. On the SUN2000 app, choose Tool Kit > Local maint script > Inverter Command Settings to generate an upgrade boot script file (boot script file for short).
  4. Import the boot script file to a PC.
  5. Replace the boot script file in the upgrade package (sun_lmt_mgr_cmd.emap) with the one generated by the SUN2000 app.
  6. Copy the extracted files to the root directory of the USB flash drive.
  7. Connect the USB flash drive to the USB port. The system automatically identifies the USB flash drive and executes all commands specified in the boot script file. View the LED indicator to determine the operating status.

    Verify that the ciphertext in the boot script file matches the login password of the SUN2000 app. If they do not match and you insert the USB flash drive for five consecutive times, the user account will be locked for 10 minutes.
