Overview
•
Integrated interface.
•
Where to connect: Terminal strip inside the inverter.
-
750 V models: 4 RS485 terminals on 10 pin terminal strip.
-
850 V models: 4 pin RS485 terminal strip.
•
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
•
ready-made Sunways 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 is connected, terminate the inverter according to the instructions for the inverter.
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
-
750 V models: 4 RS485 terminals on 10 pin terminal strip
-
850 V models: 4 pin RS485 terminal strip
The RS485 connections on the terminal strip are each double connections so that the wiring can be continued to
the next inverter.
