7.5.1.2 STATUS SUMMARY
In the Status Summary sub-menu you can view the detailed
information related the status and the production data of the
system.
7.5.2 SETTINGS menu
In the SETTINGS section it’s possible to access the following sub-
menus:
INVERTER PARAMETERS
• AC output Rating (Only visible with Admin Plus privileges)
• AC Settings (Only visible with Admin Plus privileges)
• Active Power Control (Only visible with Admin Plus privileges)
• Additional Functions (Only visible with Admin Plus privileges)
• DC Settings
• Digital Inputs
• Frequency Control: P(f) (Only visible with Admin Plus privileges)
• Ramp Control (Only visible with Admin Plus privileges)
• Reactive Power Control (Only visible with Admin Plus privileges)
DIGITAL OUTPUTS
7.5.2.1 INVERTER PARAMETERS > AC output Rating
(Only visible and editable with Admin Plus
privileges)
In the AC output Rating sub-menu you can config the output power
limitation by changing the Maximum AC output power and the
maximum apparent output power parameters.
NOTE –
D
Do not change these parameters if not requested
by the grid operator.
7.5.2.2 INVERTER PARAMETERS > AC Settings (Only
visible with Admin Plus privileges)
In the AC Settings sub-menu you can setup the parameter related
to the Output AC side.
NOTE –
D
Changing the above-mentioned parameters may
prevent disconnection from the grid if the new values exceed
those given in the standards of the country of installation.
If these parameters are changed to values outside the
standard range, an interface protection must be installed
external to the inverter in accordance with the requirements
of the country of installation.
•
Grid Connection
By editing these settings it’s possible to change the grid
connection thresholds parameters to which the inverter have to
connect to the grid.
•
Grid Prote VRT/FRT
By editing these settings it’s possible to enable/disable and
change the grid protection intervention thresholds parameters.
In addition it is possible to change voltage ride through (HVRT,
LVRT) and frequency ride through (HFRT, LFRT) settings.
7.5.2.3 INVERTER PARAMETERS > Active Power
Control (Only visible and editable with Admin
Plus privileges)
In the Active Power Control sub-menu you can config settings
related to the active power derating parameters using the following
parameters groups:
• Active Power Curtailment
• CEI Average VGrid Derating
• Volt/Watt settings: P(V)
NOTE –
D
Do not change these parameters if not requested
by the grid operator.
7.5.2.4 INVERTER PARAMETERS > DC Settings
In the DC Settings sub-menu you can setup the parameter related
to the Input DC side.
• Multiple Max Scan Enable
This settings allows you to Enables/disables the scan for
identifying the maximum power point of the system.
• Multiple Max Scan Period - Value
This settings allows you to sets the time between scans.
Remember that the shorter the scan interval the greater the loss
of production, due to the fact that energy is transferred to the grid
during the scan but not at the maximum power point. Each scan
takes roughly 2 seconds.
• UV Protection Time - Value
This section of the menu allows you to sets the time for which the
inverter stays connected to the grid after the input voltage has
dropped below the Under Voltage limit (set at 70% of Vstart).
NOTE –
D
60 seconds is the default value for UV Protection
Time.
• VStart 1...16 New Value
These parameters are used to sets the Vstart activation voltage
for the related input channel. This parameter imposes a minimum
input voltage on the inverter above which connection to the grid
will be attempted.
NOTE –
D
Change the activation voltage only if really
necessary and to set it to the correct value: the photovoltaic
generator sizing tool available on the Fimer website will
indicate whether Vstart needs to be changed and what value
have to be set.
7.5.2.5 INVERTER PARAMETERS > Digital Inputs
In the Digital Inputs sub-menu you can disable or enable the
Remote ON/OFF functionality related to the “Remote” terminal
block
(38)
.
7.5.2.6 INVERTER PARAMETERS > Frequency Control:
P(f) (Only visible and editable with Admin Plus
privileges)
In the Frequency Control: P(f) sub-menu you can config settings
related to the active power derating as function of grid frequency.
NOTE –
D
Do not change these parameters if not requested
by the grid operator.
7.5.2.7 INVERTER PARAMETERS > Ramp Control (Only
visible and editable with Admin Plus privileges)
In the Ramp Control sub-menu you can config the parameter
related to the active power ramp up at the start-up and after a grid
fault event.
NOTE –
D
Do not change these parameters if not requested
by the grid operator.
7.5.2.8 INVERTER PARAMETERS > Reactive Power
Control (Only visible and editable with Admin
Plus privileges)
In the Reactive Power Control sub-menu you can configure
settings related the reactive power parameters using the following
parameters groups:
• Cosphi Set
• Q Set
• Volt/VAr Settings: Q(V)
• Watt/Cosphi Settings: Cosphi(P)
NOTE –
D
Do not change these parameters if not requested
by the grid operator.
