Single MPP Tracker mode with just one string on a Multi MPP Tracker inverter:
Connecting just one string to a Multi MPP Track-
er inverter
If only one string is used for connec-
tion 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.
Multi MPP
Tracker Inverter
– Fronius Primo
10.0–15.0
Multi MPP Tracker inverters have 2 independent DC inputs (MPP Tracker). These
inputs can be connected to a number of different modules.
MPP Tracker 1 has 4 DC+ terminals.
MPP Tracker 2 has 2 DC+ terminals.
There are a total of 6 DC- terminals.
Connecting 2-6 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).
