Overview
•
Interface not integrated; Retrofit RS485 interface card.
•
4-pin cable – only on RS485/422 B connection of the Solar-Log™
•
Communication address does not have to be assigned
•
Multi-string technology
The inverters are fitted with 1 or 3 MPP trackers depending on the model. Each string input is monitored
separately and ideally adjusted to the connected modules.
The Solar-Log™ automatically detects how many inverters and strings are active during inverter detection.
Note
The order in which the inverters are displayed in the Solar-Log™ after detection is random.
We strongly recommend that you change the order of the inverters immediately after de-
tection at startup, in the
Configuration/Basis/Inverters dialog box.
The inverters can be identified using the displayed serial number.
•
Installation steps
• Switch off the inverters and Solar-Log™
• Install the RS485 interface in the inverter
• Connect inverters to the Solar-Log™
• Connect the inverters to each other
Procedure
► Insert the RS485 interface in the bottom of the inverter in accordance with the interface card installati-
on instructions and screw in.
Connect inverters to the Solar-Log™
The wiring is done using a
•
ready-made BKL1 data cable (optional extra; not supplied)
or
•
self-made, shielded 4 wire data cable and terminal block connector.
Note
Only connect inverter using the RS485/422 B interface.
