Inverters from different Albatech model ranges (APL monophase / triphase) cannot be mixed on an RS485 connec-
tion. The correct range must be selected when selecting inverters.
Overview
•
Integrated interface.
•
Where to connect: Terminal strip inside the inverter.
•
3-pin wiring.
•
Communication address must be allocated.
•
Installation steps:
• Allocate communication address.
• Switch off the inverters and Solar-Log™.
• Connect inverters to the Solar-Log™.
• Connect the inverters to each other.
Note
If more than 32 inverters are connected a signal amplifier must be installed in the RS485 bus in accor-
dance with the manufacturer.
Connect inverters to the Solar-Log™
The wiring is done using a
•
self-made, shielded 3 wire data cable and terminal block connector.
It is connected to the inverter as shown in the following diagram. The inverters are terminated on pin 9/10 of J1.
Both the first and also the last inverter must be terminated.
