3.2.5.1 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 GmbH off ers the following units:
Powador-proLOG S to XL (optional)
Powador-proLOG allows you to monitor up to 31 inverters simultaneously. Depending on the product version,
Powador-proLOG sends yield and operating data by SMS or e-mail.
Powador-link RS485 (optional)
Use the Powador-link RS485 to bridge long distances between several inverters or between an inverter and the
Powador-proLOG by means of wireless radio transmission.
3.2.5.2 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.
3.2.5.3 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.
3.2.5.4 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).
The S0 interface pulse rate can be chosen in three unit intervals (500, 1,000 and 2,000 pulses/kWh).
