17. Commissioning (continuation)
• STEP 4 - Type of coupling, Inverter country standard, Input mode, Meter and Energy policy, Battery and Backup mode configuration
System configuration
- DC coupled (new installations). Select this mode if the inverter is con-
nected to the AC network and to the photovoltaic generator.
- AC coupled (retrofit with existing solar inverters). Select this mode if the inverter is connected only to
the AC network and in combination with a standard inverter connected to the photovoltaic generator.
Country standard
Set the grid standard of the country in which the inverter is installed.
From the moment that the grid standard is set, you have 24 hours to make any changes to the
value, after which the "Country Select > Set Std." functionality is blocked, and the remaining
time will have to be reset in order to have the 24 hours of operation available again in which
to select a new grid standard (follow the procedure "Resetting the remaining time for grid
standard variation" described in the relevant section).
Input mode (not available if "AC coupled" system configuration was selected)
- Indipendent
- Parallel
See the relevant section of this guide to know how to physically set the input mode
Meter
When a meter device is connected to the inverter, it's requested to select the meter model:
- Meter Model:
None (where system is installed without meter)
REACT-MTR-1PH (single-phase)
ABB 3PH (three-phase)
ABB 1PH (single-phase)
If a 3PH energy meter (ABB B23, B24) is used in the system as single-phase inverter, it will be
necessary to select ABB 3PH and the phase to which the inverter is connected.
If the selected meter is three-phase additional requested fields will appear:
- Meter Phase: select the phase to which the inverter is connected.
When a meter type is selected is possible to set also the Energy Policy fields that allows to manage the energy produ-
ced by the PV plant.
Battery
- Battery Type. Select REACT2-BATT.
- Number. Set the number of REACT2-BATT (battery unit) installed.
Energy Policy
- Energy Policy: set the way to manage the energy produced by the PV plant, choosing from the following:
Management mode
Zero injection
Self consumption
Custom
- Backup Mode:
Set the way to manage the backup funtionality, choosing from:
AUTO. The necessary condition for activating the backup function is the lack of grid.
External Control. The backup function is controlled by an external command.
Confirm the settings by clicking "DONE" and the inverter will test the meter and the battery working and it will reboot
at the finish of test phase.
A notification will confirm that the wizard is completed.
• After the wizard is completed, the system will power-on. The inverter checks the grid voltage, measures the insulation resistance of the photo-
voltaic field with respect to ground and performs other auto-diagnostic checks. During the preliminary checks on the parallel connection with
the grid, the "Power" LED keeps flashing, the "Alarm" and "GFI" LEDs are off.
If the outcome of the preliminary checks on the grid parallel is positive, the inverter connects to the grid and starts
to export power to the grid. The "Power" LED remains fixed on while the "Alarm" and "GFI" LEDs are off.
To address any problems that may occur during the initial stages of operation of the system and to ensure the inverter remains
fully functional, you are advised to check for any firmware updates in the download area of the website www.abb.com/solarinver-
ters or at https://registration.abbsolarinverters.com (instructions for registering on the website and updating the firmware are
given in this manual).
Description
The system automatically manages power flows in order to avoid the injection of energy to the grid. If the meter is discon-
nected or not working the inverter's output power is restricted to zero in order to avoid accidental power feeding to the grid.
The system automatically manages power flows in order to maximise self-consumption. All unused power from domestic
loads will feed into the grid.
The system automatically manages power flows in order to avoid feeding the grid with power greater than: PDC x Plim
where PDC is the power of the photovoltaic generator ("PV GENERATOR POWER" parameter) and Plim is the output power
limit with respect to PDC(%) ("FEED-IN POWER" parameter).
- PV Generator Power (Wp): Insert the power value of the photovoltaic system installed.
- Feed-in Power (% PV Generator Power): Set the percentage AC power restriction (with reference to the value of the photo-
voltaic system (kWp) installed) to be feed into the grid.
