8 Visiting and Configuring the Webserver

8.1 User and Authority

The Webserver provides user permission and installer permission:

User permission (by default): Username is user and the password 1111.

Installer permission: Select the username installer through the drop-down list. The password is 2222.

Abnormality may be caused if users make parameter modification on the Webserver with installer permission. The loss caused in this case is out of any or all warranty rights.

To avoid two or more persons to change the inverter configurations at the same time, only one person can login to Webserver at a time. Therefore, once a person logs in and does not exit, other person cannot log in anywhere else. Close the webpage when logging out. After logging out, it will take at most 4s until the user log in again.

8.2 Login Interface

1. Query the inverter IP address corresponding to the instructions in“7.7.7 Setting Communication Parameters”.

2. Open the browser and input the inverter’s IP address. Press“Enter” to enter the login interface.

3. Select the username and input the corresponding password according to the visitor's role. Press “Sign in” or “Enter” to log in.
