Multi-string technology
The Trannergy inverters are fitted with 1 or 3 MPP trackers depending on the model. Each string input is monito-
red 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 detection at startup, in the
Configuration | Devices | Configuration | Order 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
Installing the RS485 interface
