In the Active Power Control
to the active power derating parameters using the following parameters
groups:
1. Active Power Curtailment
2. CEI Average VGrid Derating
3. Volt/Watt settings: P(V)
Do not change these parameters if not requested by the grid operator.
In the DC Settings sub-menu you can setup the parameter related to
the Input DC side:
VStart 1 New Value
This parameter is used to sets the Vstart activation voltage for the input
channel 1. This voltage imposes a minimum input voltage on the inverter
above which connection to the grid will be attempted.
VStart 2 New Value
This parameter is used to sets the Vstart activation voltage for the input
channel 2. This voltage imposes a minimum input voltage on the inverter
above which connection to the grid will be attempted.
Change the activation voltage only if really necessary and to set it to the correct value: the
photovoltaic generator sizing tool available on the ABB website will indicate whether Vstart
needs to be changed and what value have to be set.
Input Mode - Independ / Parallel
UV Protection Time - Value
This section of the menu allows you to sets the time for which the in-
verter stays connected to the grid after the input voltage has dropped
below the Under Voltage limit (set at 70% of Vstart).
(60 seconds is the default setting).
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.
In the Digital Inputs sub-menu you can disable or enable the Remote
ON/OFF functionality related to the "Remote" terminal block
(Only visible with Admin Plus privileges)
