Connecting the inverters
Solutronic SP100, SP120 (RS485)
46 of 268 Solar-Log
1000/500/200
Installation
4.15 Solutronic SP100, SP120 (RS485)
Overview
Interface integrated
Where to connect: Round pin plug on the outside of the inverter.
3 pin wiring
Communication address must be allocated.
All inverters must be fitted with firmware version 1.2.39 or later.
Inverters must be earthed otherwise this could lead to problems with
inverter detection.
Work steps
• Switch off the inverters and the SolarLog™; Page 17
• Connect inverters to the Solar-Log™
• Connect the inverters to each other
• Allocate communication address
Connecting inverters to the Solar-Log™
ready-made data cable (optional extra; not supplied)
or
self-made, shielded 3 wire data cable and terminal block connector
( Page 15).
Procedure
1 If you are fabricating the cable yourself, connect the wires as shown in the
following diagram:
Solar-Log™ terminal block connector
2 Terminate pin 1 on the terminal block connector and pin 4 on the Solar-
Log™ using the 120 Ω terminal resistor.
3 Terminate on the inverter in accordance with the manufacturer's handbook.
4 Close the inverter if no other inverters are to be connected.
5 Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connecting the inverters to each other (Solar-Log
500
, Solar-Log
1000
)
Connection in the master-slave data network using a 1:1 cable with
M12 plug connector (available as an optional extra from Solutronic)
Sockets X6 and X7 are connected to each other electrically.
Where to connect: Round pin plug on the outside of the inverter.
