Kaco
48.2 Kaco – PVI Blue Planet
Termination Addressing Interface
Yes Yes RS485
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:

4. If no further inverter connected, terminate the inverter:
In the inverter connect the free terminal A to terminal B using the supplied 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
•
Connect using a 2 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.
