Install KOSTAL Smart Energy Meter as shown at the grid
connection point in the home network.
Set up RS485 communication cable between inverter
and KOSTAL Smart Energy Meter RS485 (B) and
connect.
Set up RS485 communication cable between bat-
tery and KOSTAL Smart Energy Meter RS485 (A) and

Establish LAN connection from KOSTAL Smart Energy
Meter, battery and inverter to the Internet. As an option,
the LAN connection from the inverter or battery can also
be connected directly to the KOSTAL Smart Energy
Meter (switch function).
In this variant, the KOSTAL Smart Energy Meter runs as
a master and transmits data to the inverter and battery.
INFO
The installation position of the
KOSTAL Smart Energy Meter can no
longer be set in the PIKO MP plus
when battery management is acti-
vated in the KOSTAL Smart Energy
Meter. It is absolutely essential that
the KOSTAL Smart Energy Meter is
fitted at the grid connection point.
INFO
For details, see the inverter's operat-
ing manual and the KOSTAL Smart
Energy Meter's installation instruc-
tions.
