With a multiple-inverter connection, there are several
KOSTAL solar inverters in the same home network.
Only one KOSTAL Smart Energy Meter is required to
monitor power and limit feed-in at the grid connection
point. This is installed at the grid connection point in the
home network as shown in the illustrations.
Depending on inverter type, the communication cable
between the inverter and the KOSTAL Smart Energy
Meter is either connected to the RS485 or LAN interface
of the KOSTAL Smart Energy Meter.

INFO
In this variant, the KOSTAL Smart
Energy Meter runs as a master and
transmits data to all KOSTAL solar
inverters in the home network. For
data visualisation, the KOSTAL Smart
Energy Meter should also be set up
as an inverter in the solar portal.
INFO
If using a multiple-inverter connec-
tion with a PLENTICORE plus, this
is currently only possible without a
battery. The smart battery control in
the PLENTICORE plus should also be
deactivated.
