Operation and operating the device
Power limitation
A feed-in limit for the entire system with a multiple-in-
verter connection measured by the KOSTAL Smart
Energy Meter can be set in the “Manage feed-in capac-
ity” menu.
The power limitation monitors the feed-in of the entire
system. If the value set for the feed-in limit is exceeded,
the KOSTAL Smart Energy Meter calculates the amount
by which each connected inverter needs to reduce its
output to avoid exceeding the feed-in limit. The “maxi-
mum output power” value set for each individual inverter
provides the basis for calculating the amount by which
each inverter needs to reduce its output.
n
The feed-in check and communication with the
inverters is started by selecting “Activate power
limitation”.
n
The maximum amount which may be fed in by the
entire system is entered in the “Feed-in capacity limit”
field. The feed-in capacity calculator can be used to
simplify calculations.
n
Under “Advanced”, the interval for communication
between the KOSTAL Smart Energy Meter and
inverters can be changed and a time period selected
for calculating the mean value. This should only be
done if problems arise.
INFO
Note regarding power limitation
with several inverters
When limiting power, every connect-
ed inverter is reduced by the same
amount (as a percentage) of its maxi-
mum output power.
If the connected inverters have dif-
ferent amounts of maximum output
power, the power reduction for each
inverter is individual.
