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 only one inverter is to be connected this must be terminated (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.
