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:

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.
