3.2.3 Electrical functions
3.2.3.1 Fault signal relay
A potential-free relay contact is integrated in the inverter. The contact closes as soon as there is a fault during operation.
3.2.4 Interfaces
The inverter off ers the following interfaces for communication and remote monitoring:
• RS485 interface
• Ethernet interface
• USB interface
• S0 interface
The confi guration of communication interfaces is via the inverter menu.
3.2.4.1 RS485 interface
Use this monitoring variant if you cannot check the function 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 authorised electrician.
For monitoring your PV system using the RS485 interface, KACO new energy off ers several solar monitoring devices.
3.2.4.2 Ethernet interface
The 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 monitoring
system.
3.2.4.3 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.
3.2.4.4 S0 interface
The S0 interface transmits pulses between a pulsing counter and a tariff metering unit. It is a galvanically isolated transis-
tor output. It is designed according to DIN EN 62053-31:1999-04 (Pulse output devices for electromechanical and elec-
tronic meters).
The S0 interface pulse rate can be chosen in three unit intervals (500, 1,000 and 2,000 pulses/kWh).
