Overview
•
Integrated interface.
•
Where to connect: Terminal strip inside the inverter.
•
3-pin wiring.
•
Communication address must be allocated.
•
Installation steps:
• Switch off the inverters and the Solar-Log™.

• Connect the inverters to each other.
• Assign the communication address.
Connect the inverters to the Solar-Log™
The wiring is done using a
•
self-made, shielded 3-wire data cable and terminal block connector.
Procedure
1. Open the inverter according to the inverter‘s instructions.
2. Pull the free wires through the wire opening in the inverter.
3. If you are making the cable yourself, connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector Inverter terminal strip
Terminal Terminal
► 1 (Data+) ► 3 (Data+)
► 4 (Data-) ► 4 (Data-)
► 3 GND ► 2 GND
4. If no further inverter connected, terminate the inverter:
Set the switch inside the inverter to ON and all other inverters to OFF.
5. Close the inverter if no other inverters are to be connected.
6. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connect the inverters to each other
•
Connect using a 3-wire, shielded data cable.
•
Where to connect: Terminal strip inside the inverter.
The RS485 connections on the terminal strip are each double connections so that the wiring can be continued to
the next inverter.
