● The login password is the same as that for the SUN2000 connected to the app
and is used only when the SUN2000 connects to the app.
● The initial passwords for Common User, Advanced User, and Special User are
all 00000a.
● Use the initial password upon rst power-on and change it immediately after
login. To ensure account security, change the password periodically and keep
the new password in mind. Not changing the initial password may cause
password disclosure. A password left unchanged for a long period of time may
be stolen or cracked. If a password is lost, devices cannot be accessed. In these
cases, the user is liable for any loss caused to the PV plant.
● During the login, if ve consecutive invalid password entries are made (the
interval between two consecutive entries is less than 2 minutes), the account
will be locked for 10 minutes. The password should consist of six characters.
● If you log in to the SUN2000 app after the device connects to the app for the
rst time or factory defaults are restored, the quick settings screen will be
displayed. If you do not set SUN2000 basic parameters on the quick settings
screen, the screen is still displayed when you log in to the app next time.
● To set SUN2000 basic parameters on the quick settings screen, switch to
Advanced User. If you log in as Common User or Special User, enter the
password of the advanced user to access the Quick Settings screen.
