Select "AROS: SIRIO RS485" during the inverter detection.
Overview
•
Integrated interface.
•
Where to connect: Terminal strip inside the inverter.
•
3-pin wiring.
•
Communication address does not have to be assigned.
Note
The order in which the inverters are displayed in the Solar-Log™ after detection is random. We strongly
recommend that you change the order of the inverters immediately after detection at startup in the
Configuration | Device | Configuration | Order menu box.
► The inverters can be identified using the displayed serial number.
•
Installation steps
• Switch off the inverters and Solar-Log™.
• Connect inverters to the Solar-Log™.
• Connect the inverters to each other.
Connect inverters to the Solar-Log™
The wiring is done using a
•
self-made cable connection with terminal block connector.
Procedure
1. If you are making the cable yourself, connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector RJ45 inverter
Terminal PIN
► 1 ► A (+)
► 3 ► GND
► 4 ► B (-)
2. If no further inverter is connected, terminate the inverter according to the instructions for the inverter.
3. 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.
