Interfaces
You can configure the interfaces and the web server in the Settings menu. The device has the following interfaces for
communication and remote monitoring.
Ethernet interface
The device features two switched Ethernet ports to enable the user to, for example, connect several devices in series if
the user prefers a linear topology.
RS485-Interface
The device features two RS485-Interfaces. One RS485-Interface is earmarked for communication with a string-combiner-
box. This can be controlled using the Modbus RTU protocol. Data loggers that cannot be connected via Ethernet can be
connected to the other RS485-Interface. The Sunspec and KACO protocol are supported in this case.
USB interface
The USB connection of the device is a type A socket. It is located on the communication circuit board on the inside of the
housing doors. The USB connection is specified to draw 500 mA of current.
Use the USB interface to read out stored operating data, load software updates or device configurations using a FAT32-
formatted USB stick.
It is possible to establish a connection to the webserver integrated into the device by connecting a USB-WiFi stick. In addi-
tion to starting up the device, the web interface can be used for service information purposes, software updates and for
carrying out extensive configuration.
“Inverter Off” input
In addition to the safety functions, the internal interface switches can also be actuated via the "Inverter Off" input.
The Powador-protect or a protective device from another manufacturer can be used for this purpose.
If a Powador-protect is used as the central interface protection, the fail-safe disconnection of suitable KACO inverters
from the public grid can be carried out by the internal interface switches instead of separate interface switches. This re-
quires the inverters in the photovoltaic system to be connected to the Powador-protect.
Information on installation and use can be found in this manual, in the Powador protect manual and in the instructions
for use of the Powador protect on the KACO web site.
At the “Inverter Off” input, instead of the Powador-protect an interface protection device from another supplier can also
be connected to actuate the internal interface switches.
Digital inputs
It is possible to enhance the device with additional digital inputs by way of an expansion module (available from KACO
Customer Service). This can be used to connect a ripple control receiver or a protective shutdown system.
