Device and system description
Recording home consumption
Using the KOSTAL Smart Energy Meter enables the
inverter to monitor the flow of energy in the home for 24
hours and to control it in an optimum manner.
The inverter takes precedence in control matters. The
PV energy generated is used firstly for self-consumption
(such as lighting, washing machine or TV). Only once
self-consumption is covered can the energy generated
above and beyond this be stored in a battery or fed into
the public grid.

24-hour measurement
Multiple-inverter connection
With a multiple-inverter connection, there are several
KOSTAL solar inverters in the same home network. By
installing the KOSTAL Smart Energy Meter at the grid
connection point, the flow of energy from all KOSTAL
solar inverters present in the home network can be
measured and regulated by the KOSTAL Smart Energy
Meter using control information, e.g. for power limitation
in order to limit the feed-in to the public grid. The benefit
of this setup is that only one energy meter is required for
all KOSTAL solar inverters in the home network.

Simultaneous power curtailment of several KOSTAL
solar inverters in the same home network
n
Saving costs by using just one energy meter
