General information
1.1 Proper use
The KOSTAL Smart Energy Meter is a measuring device,
which determines electrical measuring values and is
available to the inverter via LAN or RS485. It is not an
electricity meter for measuring active consumption in the
sense of the EU Directive 2004/22/EC (MID) and it may
only be used for internal purposes.
The data about your system’s energy generation
collected by the KOSTAL Smart Energy Meter may
deviate from the data of the main energy meter.
According to its classification as overvoltage category
III, the KOSTAL Smart Energy Meter may only be
connected in the sub-distribution / circuit distribution on
the consumer side behind the energy supply company’s
energy meter and is only suitable for indoor use.
The KOSTAL Smart Energy Meter is approved for use in
EU member states. Only use the KOSTAL Smart Energy
Meter in accordance with the details provided in the
enclosed documentation.
Any other form of use may result in damage to property
or personal injury. For reasons of safety, the product
(including the software) must not be modified and

technicians or engineers. When doing so, all
requirements are to be observed.
IMPORTANT
INFORMATION
The KOSTAL Smart Energy Meter
may only be installed, maintained
and repaired by a trained and quali-
fied electrician.

1.4 Notes in this manual
Installation
Install a line circuit breaker into the mains cable
between the inverter and the feed meter to
secure it against overcurrent.
In countries in which a second PE connection
is prescribed, connect this at the marked place
on the housing.
Connecting AC-side
Connect the wires of the mains cable to the
AC terminal in accordance with the labelling.
For connection with a computer or with a
computer network. Connect several inverters
to a network for data retrieval.
DANGER
De-energise the device,
secure it against being
restarted and wait five
minutes so that the capaci-
tors can discharge.
Risk of death due to electrical
shock and discharge!
IMPORTANT NOTE
To connect the AC cables,
the inverter is equipped with
spring-loaded terminal strips.
INFO
For connection with a
computer, an Ethernet cable
of category 6 is to be used.

Device and system description
2.1 Using the KOSTAL Smart Energy Meter
The KOSTAL Smart Energy Meter (KSEM) is a measuring
device, which determines electrical measuring values
at the grid connection point and is available via LAN
or RS485. It can be used in combination with various
KOSTAL solar inverters and batteries.
This includes the following inverters:
n PLENTICORE plus
n PLENTICORE BI
n PIKO IQ
n PIKO MP plus
n PIKO 4.2-20
n PIKO EPC
These can be used in combination with the KOSTAL
Smart Energy Meter for the following applications:
n reading the current home consumption and output
power
n Power curtailment of inverters down to 0W
n If several PV systems in the same home network
share a multiple-inverter connection, only one
KOSTAL Smart Energy Meter is required at the grid
connection point
n If using PIKO MP plus with a battery, the battery
management, which controls the battery’s charging
/ discharging, is taken over by the KOSTAL Smart
Energy Meter,
n sending consumption data to the KOSTAL Solar
Portal
