•1 level
a) The first line displays the parameters(Power, Today and Total) and the values.
b) The second line shows the running status.
Namely, “Power” means the timely output power;
“Pgrid” means the power export to or import from the grid; (Positive value means
the energy feeds into the grid, negative value means the energy used from the grid)
“Today” means the power generated within the day.
“Normal” means the status of the inverter.
•2 level
Long press any first-level parameter can enter the second-level “Status” parameter
interface.
The user can also see other parameters, such as the Language( without password ),
Setting ( need password ), Meter energy, Error Logs of the inverter, and About ( the
user can watch the information of the inverter).
•3 level
Long press the second-level parameter can enter the corresponding third-level
parameter interface.
a) Status: The user can see the U/I/P parameters of the grid and the PV, such as the
Ugrid, Igrid, PF value of the grid, and the Usolar, Isolar and Psolar of the PV.
b) Language: This inverter provides several languages for customer to choose.
c) Setting: Entering the installer password, the information of the LCD interface is
as the previous page shown.
(1) Safety: The user can set the right safety standard here.
(2) Grid: Usually end user does not need to set the grid parameters. All default
value have been set before leaving factory according to safety rules.
If need to reset, any changes should according to the requirement of local grid.

For VDE ARN 4105, curve cos φ = f(P) should refer to curve A. default values of setting are as
shown in curve A.
For E 8001, curve cos φ = f(P) should refer to curve B. default values of setting are as shown in
curve B.
