Overview
•
Integrated interface.
•
Where to connect: RJ45 socket.
•
2-pin wiring.
•
Communication address must be allocated.
•
Installation steps:
• Switch off the inverters and Solar-Log™

• Allocate communication address
Note
When a device has four MPP trackers, this will be recorded as a single MPP tracker.
► With firmware version 4.1.0 or higher, four MPP trackers are recorded.
Connect inverters to the Solar-Log™
The wiring is done using a
•
self-made shielded, 2-wire data cable 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 socket inverter
Terminal PIN

► 4 ► 3 (Data -B)
2. Insert the plug into the socket on the inverter
3. If no further inverter is connected, terminate the inverter according to the instructions for the inverter.
