Termination Addressing Interface
Yes Yes RS485
Note
The same protocol must be selected on both devices In order to ensure correct communication bet-
ween the Solar-Log™ and the inverters.
Protocol selection for device detection:
•
Q3: Protocol 1
•
Q3: Protocol 9
The following types are to be connected according to this diagram:
•
QX12000
•
QX14000
Overview
•
Integrated interface
•
Where to connect: Round pin plug on the outside of the inverter
•
3-pin wiring
•
Communication address must be allocated
•
Inverters must be grounded otherwise this could lead to problems with inverter detection
•
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™
•
self-made, shielded 3 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:
Solar-Log™ terminal strip connector Inverter terminal strip
Terminal Terminal
► 1 ► 2 - Data +
► 3 ► 3 - Ground
► 4 ► 4 - Data -
2. Terminate pin 1 on the terminal block connector and pin 4 on the Solar-Log
TM
using the 120 Ω terminal resis-
tor.
3. Terminate on the inverter in accordance with the manufacturer‘s handbook.
4. Insert the terminal block connector into the Solar-Log™ RS485 socket.
