SUN2000 APP
NOTE
1. The SUN2000 APP enables the inverter to communicate with the monitoring system through a
USB data cable or Bluetooth for you to query alarms, configure parameters, and perform routine
maintenance. The SUN2000 APP is a convenient platform for local monitoring and maintenance.
The APP name is SUN2000.
2. Mobile operating system: Android 4.0 or later.
3. Access the Huawei app store (http://appstore.huawei.com) or Google Play
(https://play.google.com), search for SUN2000, and download the SUN2000 APP installation
package.
4. Connect a USB data cable or a Bluetooth module to the USB port of the inverter to implement the
communication between the inverter and the APP.
