B
Applies to large-scale commercial ground PV plants with PV strings facing the
same direction.
In AC or DC power limiting scenarios:
– If the PV string access type is not identified, the value of PV Status will
keep being displayed as Not connected. The PV string access type can be
identified only when the inverters restore to the non-power limiting state
and the current of all connected PV strings reaches the startup current.
– If the PV string access type has been identified, when some PV strings
connected to the 2-in-1 terminals are lost, no alarm will be generated. If
some PV strings connected to the 2-in-1 terminals are restored, the
access type cannot be identified. It can be determined whether all the 2-
in-1 PV strings are restored only when the string current reaches Startup
current for 2 in 1 detection.
NO TE
Use the initial password upon first 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.
