Multi-string technology
The Trannergy 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.
