3.1.3 Interfaces
The inverter has the following interfaces for communication and remote monitoring:
• RS485 interface
• Ethernet interface
• USB interface
• S0 interface
You confi gure the interfaces and the web server in the Settings menu (see section 8.3 on page 33).
3.1.3.1 RS485 interface
Use this monitoring option if you cannot check the functioning of the system on-site on a regular basis, e.g. if your
place of residence is located a great distance from the system. To connect the RS485 interface, contact your author-
ised electrician.
For monitoring your PV system using the RS485 interface, KACO new energy GmbH off ers monitoring devices:
3.1.3.2 Ethernet interface
Monitoring can occur directly on the unit using the integrated Ethernet interface. A local web server is installed in
the unit for this purpose.
For monitoring a system comprising several inverters, we recommend you use an external data logging and moni-
toring system.
3.1.3.3 USB interface
The USB connection of the inverter is a type A socket. It is located on the connection board on the underside of the
inverter under a cover. The USB connection is specifi ed to draw 100 mA of power. Use the USB interface for reading
out stored operating data and loading software updates using a FAT32-formatted USB stick.
3.1.3.4 S0 interface
The S0 interface transmits pulses between a pulsing counter and a tariff metering unit. It is a galvanically isolated
transistor output. It is designed according to DIN EN 62053-31:1999-04 (pulse output devices for electromechanical
and electronic meters).
NOTE
The S0 interface sends a specifi c number of pulses per kilowatt-hour output.
The number of pulses per kilowatt-hour output that can be sent by the S0 interface depends on the
maximum feed-in power of the inverter and can be set in the menu.
30.0-36.0 TL3 500, 1,000 or 2,000 pulses/kWh.
39.0-60.0 TL3 500 or 1000 pulses/kWh
72.0 TL3 500 pulses/kWh
3.1.3.5 Digital input "inverter off "
If Powador protect is installed as a central grid and system protection, the fail-safe disconnection of suitable Pow-
ador inverters from the public grid can be initiated by a digital signal instead of tie circuit-breakers. This requires the
inverters in the photovoltaic system to be connected to the Powador protect. For information on the installation
and use see this manual, the Powador protect manual and the instructions for use of the Powador protect on the
KACO web site.
