Dynamic Feed-in Control
In the Dynamic Feed-in Control sub-menu it’s possible to enable the
management of power ows in order to optimize self-consumption or
avoid feeding power to the grid (except during transitory), basing on the
reading of the energy meter:
Installation of energy meter is required. Refer to the section “Connection of the energy meter”
in the manual for the meter connection.
- Meter:
When a meter device is connected to the inverter, it’s
requested to select the meter model:
1. None (where system is installed without meter)
2. REACT-MTR-1PH (single-phase)
3. ABB 1PH (single-phase)
4. ABB 3PH (three-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.
Once the meter model is selected, additional requested
elds will appear:
- METER PHASE: If the METER is three-phase, the
phase to which the inverter is connected must be
selected. (This eld will appear only if you select
the ABB B23 3PH meter model)
