Multi-string technology

Mastervolt inverters are fitted with 1 or 2 MPP trackers depending on the model. Each string input is moni-

tored 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 de-

tection at startup, in the Configuration/Basis/Inverters dialog box.

The inverters can be identified using the displayed serial number.
