No DIP switch Yes RS485
Overview
•
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
•
self-made, shielded 2 wire data cable with a terminal block connector.
Procedure
1. Open the inverter as shown in the inverter's instructions.
2. If you are making the cable yourself, connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector Terminal strip inside the inverter
Terminal RS485 terminal
► 1 A/Data+ ► 1 T/R 1+
► 4 B/Data- ► 2 T/R 1-
3. If only one inverter is to be connected this must be terminated.
In the inverter, set the DIP switch for the terminal resistor to ON.
4. Close inverters.
5. Insert the terminal block connector into the Solar-Log™ RS485 socket.
