Multi MPP Tracker inverters have two inde-
pendent DC inputs (MPP Tracker). These
inputs can be connected to a number of dif-
ferent modules.
Each MPP Tracker has 3 DC+ terminals.
There are a total of six DC- terminals.
Connecting two–six strings in Multi MPP
Tracker mode:
Connect the strings separately to the two
DC DC
- MPP Tracker inputs (DC+1/DC+2). The
1 2 3 4 5 6
DC- terminals can be used as desired, sin-
ce they are connected internally.
Set MPP TRACKER 2 to "ON" when star-
ting for the first time (also subsequently
possible in the basic menu)

If the inverter is being operated with an ex-
ternal string collection box, the DC connec-
tor kit (item numbers 42,0201,4479 and
42,0201,4480) must be used

Set MPP TRACKER 2 to "OFF" when star-
ting for the first time (also subsequently

If the Multi MPP Tracker inverter is opera-
ted in Single MPP Tracker mode, the cur-
rents of the connected DC lines are
distributed evenly across both inputs.
