Once the meter model is selected, additional requested
fields will appear:
- METER PHASE: If the METER is three-phase, the
phase to which the inverter is connected must be
selected. (This field will appear only if you select
the ABB B23 3PH meter model)
- ENERGY POLICY: set the way in which you want
to manage the energy produced by the PV plant,
choosing from the following:
Management
Description
mode
The system automatically manages po-
wer flows in order to maximise self-con-
sumption. All unused power from dome-
Self stic loads will feed into the grid. Using the
consumption Load Manager Relay, with the optional
COM KIT, to program a power-on/power-
off of a specific Load is it possible to in-
crease the Self-consumption ratio
The system automatically manages po-
wer flows in order to avoid the injection of
energy to the grid. If the meter is discon-
Zero injection
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 po-
wer flows in order to avoid feeding the
grid with power greater than:
Custom where P
DC
generator ("PV GENERATOR POWER"
parameter) and P
limit with respect to P
POWER" parameter).
- PV GENERATOR POWER: Insert the power value
of the photovoltaic system (kWp) installed.
- FEED-IN POWER: Set the percentage AC po-
wer restriction (with reference to the value of the
photovoltaic system (kWp) installed) to be feed into
the grid. This field can be edited only if the Energy
Policy selected is "Configurable".
Confirm the settings by clicking "END" and the inverter will
test the meter working (if selected a meter device) and it
will reboot at the finish of test phase.
