Connecting two solar module fields to a Multi
MPP Tracker inverter
Multi MPP Tracker inverters have two
independent DC inputs (MPP Tracker).
These inputs can be connected to a
number of different modules.
Each MPP Tracker has 3 DC+ termin-
als. There are a total of six DC- termin-
als.
Connecting two–six strings in Multi
MPP Tracker mode:
Connect the strings separately to the
two MPP Tracker inputs (DC+1/DC+2).
The DC- terminals can be used as de-
sired, since they are connected intern-
ally.
Set MPP TRACKER 2 to "ON" when
starting for the first time (also sub-
sequently possible in the basic menu)

Connecting multiple combined solar module
fields to a line on a Multi MPP Tracker inverter
Single MPP Tracker mode on a Multi
MPP Tracker inverter:
If the inverter is being operated with
an external string collection box, the
DC connector kit (item numbers
42,0201,4479 and 42,0201,4480) must
be used
Set MPP TRACKER 2 to "OFF" when
starting for the first time (also sub-
sequently possible in the basic menu)
If the Multi MPP Tracker inverter is op-
erated in Single MPP Tracker mode,
the currents of the connected DC lines
are distributed evenly across both in-
puts.
