When connecting the app to the SUN2000 over a router, the mobile phone and SUN2000
are within range of the router and the SUN2000 is connected to the router.
The way of connecting the SUN2000 to the router is as follows:
The installer taps Quick setting (see 7.4.4 Quick Setting for details) or Comm config (see
7.4.6 Communication Configuration for details).
The user taps Set (see 7.5.6 Settings for details).
If the WiFi signal is weak, you will be prompted to try again multiple times. Follow the instructions.
Procedure on the Android System
The app allows for connecting to the SUN2000 in the following two ways. Select either way
based on site requirements. After the connection is established, the Inverter screen is
displayed. If your mobile phone fails to connect to the SUN2000 or router WiFi network from
the app, try to connect to the WiFi network from your mobile phone system. To connect to the
router over WiFi from the mobile phone system, ensure that you have logged out of the app.
Method 1: The mobile phone connects to the SUN2000 directly.
Run the app, tap the WiFi name corresponding to the SUN2000, and enter the WiFi
password to connect to the WiFi network. Use the initial password Changeme upon first
login. To ensure account security, change the password immediately after login.
The name of the connected SUN2000 WiFi network is represented by SUN2000-its serial number (SN).
The SN can be found on the label attached to the side of the SUN2000.

SUN2000 WiFi network.
