91.2 Solutronic(SP)80,100,120,(SE)40S1,40S2,50S2,60S2(RS485)
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:
•
Solutronic: Protocol 1
•
Solutronic: Protocol 9
Overview
•
Integrated interface
•
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 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™
•
ready-made data cable (optional extra; not supplied)
or
•
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

► 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. Close the inverter if no other inverters are to be connected.
5. Insert the terminal block connector into the Solar-Log™ RS485 socket.
