3 After finishing troubleshooting, go to SCU Web interface and choose Smart Diagnosis - Fault Diagnosis - Fault Monitoring. Click on the trash bin icon in the upper left corner of the "PV module" icon to manually clear the alarm message.

9.2.5 Branch Number Setting

At the first time of grid connection, or in the event of array rearrangement, you can set parameters for each combiner box in each inverter unit on the "Branch Number Setting" page. The page is shown below.

Parameter	Range Description
Combiner Box Name	1 - 64 bytes (which is, up to 32 Chinese characters or 64 English letters/numbers)	user-definable. Default name: branch1, branch2, branch3...
Number of PVS Inputs	1 - 24; 24 by default	Indicate the number of inputs connected to the combiner box. It is suggested to set this paramete according to the actual situation before the first grid connection.

9.2.6 Advanced Settings

You can set the key parameters of the smart branch diagnosis function on the “Advanced Settings” page, such as “PV Configuration”, “Smart Branch Diagnosis”, “Initialization”, “Sensitivity Setting”, “Alert Information Upload”, and “Restore Default Configuration”.

Default values are available in the system. At the first time of grid connection or in the event of array rearrangement, you may adjust the parameter settings according to the actual situation. The page is shown below.

Parameter descriptions and suggestions on setting are listed in the table below. For other parameters, please refer to the information shown on the page.

Parameter	Description Range	Suggestions
PV Configuration	Type of PV modules	166, 182, or 210; 182 by default.	It is suggested to set this parameter in line with the actual model of PV modules in the first time of grid connection.
Sensitivity Setting	The greater the value is, the higher sensitivity gets.	1 - 7. For instance, when the sensitivity is set to “1”, a fault should occur every day for 30 days in a row to trigger an alarm. The correlation between the sensitivity setting and the time required to trigger a fault alarm is shown in the table below.	For plants where the combiner box output current is stable, you can set the sensitivity to a high level. For plants where the output current of the combiner box is prone to fluctuation due to weather or other factors, you can set the sensitivity to a low level, so as to avoid false alarms.

12 User Management

The administrator can assign different accounts and permissions to different users, which thus boosts the system's security, improves operation efficiency for users, and lowers management costs.

table 12-1 User type

User type Permissions

Super Administrator Add/delete a user, modify user information,empty users, login management, enable or disable R&D debugging.

O&M user Operations mentioned in this manual.

General user Granted access to monitoring and generalsettings. For instance, Overview, Device Monitoring, and some of the History Data.

If a General User sees a message reading “The account has been logged in elsewhere” when attempting to log into the system, it indicates an O&M User or a Developer account has been logged in somewhere else. In this case, the other users need to log out first.

• Only one user is allowed to log in at the same time.
• When adding a user, the user name should not be longer than 16 characters. The password should be 12-32 character long and contain at least three of the following three character types: uppercase letters, lowercase letters, numbers.

• If the Network Safety Mode is not turned on, the passwords of all users are permanently valid.
  Under Network Safety Mode, the Super Administrator can set passwords to expire after a number of days between 1 and 90 for different types of users.
