5.5 KACO Power Control
Since 1 January 2009 when the German Renewable Ener-
gies Act (EEG) was passed, PV systems in excess of 100 kW
have been subject to remote-controlled power regulation. In
principle, each individual unit in a network with other units
can become a system of this size. Therefore, every Powador
inverter supports power reduction.
KACO new energy achieves this power reduction function
(KACO power control) by combining the Powador-proLOG XL
unit with a radio ripple control receiver. These units enable the
power supply company to reduce the power of the system as
required. For this, the following levels are possible: 0%, 30%,
60% or 100% of the rated AC power of the inverter. When
you specify 30 % or 60 %, the inverter limits the power to
30 % or 60 %. With a setting of 0 %, the inverter disconnects
from the grid, and 100% is used for normal grid feed mode.
When the power supply company requests a reduction in
the power, the Powador-proLOG receives the corresponding
signal via the radio ripple control receiver. The Powador-pro-
LOG then forwards the information to all connected inverters
as a command via the RS485 interface. After a period of fi ve
minutes without any signal from the power supply company,
the inverters return to normal operation.
Connection
The radio ripple control receiver is connected to the Powador-
proLOG XL, which is mandatory for the use of KACO power
control. You do not have to make any changes to the inverter
in order to use the KACO power control function, since it is
integrated into the inverter as standard. It is activated and
confi gured using the Powador-proLOG XL web server or the
integrated display on the Powador-proLOG XL.

ATTENTION
To use the KACO power control function, you must insert
the adapter board. This is included in the scope of deliv-
ery of each Powador-proLOG XL unit. In other words, you
must remove the standard plug connector and insert the
adapter board instead. Now connect the radio ripple con-
trol receiver to the adapter board.
