5.4 KACO power control (XL only)
As of 01/01/2009, the German Renewable Energies Act (EEG)
requires a power regulation for systems larger than 100kW.In
principle, each individual unit in a network with other units
can become a system of this size. Therefore, each inverter
must have an option for reducing the power, even if this is not
needed in a system that is smaller than 100kW.
KACO uses a ripple control receiver to implement this power
reduction. The power supply company can use this unit to
reduce the system’s power via the Powador-proLOG XL, as
necessary. The following settings are available: 0 %, 30 %,
60 % or 100 % of the AC power. With a setting of 30 % or
60 %, the inverter limits the power to 30 % or 60 %. With
a setting of 0 %, the inverter disconnects from the grid.
Normal feed-in mode occurs at 100 %. When the power
supply company requests a reduction in the power, the Powa-
dor-proLOG receives the corresponding signal via the ripple
control receiver. The Powador-proLOG then forwards the
information to all connected inverters, which reduce power as
prescribed by the power supply company. After a specified
period of time without any signal from the power supply com-
pany, the inverters return to normal operation.
For the duration of the power reduction, the display shows the
power reduction with a corresponding message (e.g. “Externe
Begrenzung xxx %” (“External limit xxx %”)) and the LED (2)
flashes once a second. You can still use the other display func-
tions as usual during a power reduction.
The ripple control receiver is connected to the Powador-pro-
LOG XL, which is mandatory for the use of power limitation
(power control). You do not have to make any changes to the
inverter in order to use power limitation, since it is integrated
in the inverter as standard. It is activated using the configuration
pages or the integrated display on the Powador-proLOG XL.
AT T E N T I O N
To use the KACO power control function, you need
to insert the adapter board (included with every XL
unit). Remove the standard plug connector (photo on the
left) and attach the adapter board in its place (photo on
the right). Now connect the ripple control receiver to the
adapter board.
