Connecting 2–4 strings in Multi MPP Tracker mode:
Connecting two solar module fields to a Multi
MPP Tracker inverter
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 possible
in the basic menu subsequently).
Single MPP Tracker mode on a Multi MPP Tracker inverter:
Connecting multiple combined solar module
fields to a line on a Multi MPP Tracker inverter
If the strings are connected with a
string collection box and only one col-
lective line is used for connection to
the inverter, connection DC+1 (pin 2)
and DC+2 (pin 1) must be bridged.
The cable cross section of the DC con-
necting line and bridging must be the
same. Bridging the DC terminal is not
necessary because it is bridged intern-
ally.
Set MPP TRACKER 2 to "OFF" when
starting for the first time (also possible
in the basic menu subsequently).
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.
