Overview
•
The Solar-Log™ only works with Kaco Blue Planet inverters that have an RS485 interface. The
RS232 interface is not supported.
RS232 models: RS485 interface can be retrofitted by the manufacturer.
RS485 models: Integrated interface
•
Where to connect: Terminal strip inside the inverter
•
2-pin wiring
•
Communication address must be allocated.
•
Installation steps
• Switch off the inverters and Solar-Log™
• Connect inverters to the Solar-Log™
• Connect the inverters to each other
• Allocate communication address
Connect inverters to the Solar-Log™
The wiring is done using a
•
partly fabricated data cable (optional extra; not supplied)
or
•
self-made, shielded 2 wire data cable and terminal block connector.
Procedure
1. Open the inverter as shown in 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 ► B
► 4 ► A
4. If only one inverter is to be connected this must be terminated.
In the inverter connect the free terminal A to terminal B using the supplied 330 330 Ω terminating
resistor.
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

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 con-
tinued to the next inverter.
