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:
•
RefuSol: Native (for PM control)

Overview
•
Integrated interface
•
Where to connect: RJ45 socket on the bottom of 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™
To connect the Solar-Log™ and the inverters prepare cables with the following pin allocation.
Connecting the Solar-Log™ to the first inverter
Solar-Log™ (4/6 pin terminal plug)
First inverter - RS485 IN
(4-pin round plug)
Pin 1 (white)
Pin 2
Pin 4 (brown)
Pin 3
If no further inverter connected, terminate the inverter (see following item "Bus termination").
Connect the inverters to each other
Inverters must be connected to each other using shielded data cables via the RS485 connections located on the
SINVERT PVM.
The following illustration shows the main connection diagram.
