Overview
•
Integrated interface
•
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 data cable (optional extra; not supplied)
or
•
self-made, shielded 2 wire data cable and terminal block connector.
Procedure
1. If you are making the cable yourself, connect the wires as shown in the following diagram:

3 (B in)
2. If no further inverter connected, terminate the inverter:
Insert 120
Ω
terminal resistor.
3. 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
Procedure
1. Connect terminal 2 (A out) on inverter 1 to terminal 4 (A in) on inverter 2.
2. Connect terminal 1 (B out) on inverter 1 to terminal 3 (B in) on inverter 2.
3. Connect the other inverters to each other in the same way.
4. Terminate the last inverter. Insert 120
Ω
terminal resistor.
Allocate communication address
•
Recommendation: Continuous numbering starting with 1.
•
Setting: Using PC software for configuring inverters.
•
Procedure: Start according to the inverter's instructions
