Multi-string technology
Mastervolt inverters are fitted with 1 or 2 MPP trackers depending on the model. Each string input is monitored
separately and ideally adjusted to the connected modules. Some inverters are also divided internally into 2 or
even 3 individual inverters. For example, the QS6400 is recognized as 2 inverters each with 2 strings, an XL 15 as 3
independent XL5000s.
The Solar-Log™ automatically detects how many inverters and strings are active during inverter detection.
Note
A maximum of 20 inverters can be connected per RS485 bus.
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™
•
Connect inverters to the Solar-Log™
•
Connect the inverters to each other
Connect inverters to the Solar-Log™
The wiring is done using a
•
ready-made Mastervolt data cable (optional extra; not supplied)
or
•
self-made cable connection with RJ45 data cable and terminal block connector.
