Multi Mpp Tracker Inverter - Fronius Primo 10.0-15.0 - Fronius Primo 208-240 Operating Instructions Manual

Connecting just one string to a Multi MPP Tracker in-
verter
Multi MPP Track- Multi MPP Tracker inverters have 2 independent DC inputs (MPP Tracker). These inputs
er Inverter – Fro- can be connected to a number of different modules.
nius Primo 10.0– MPP Tracker 1 has 4 DC+ terminals.
15.0 MPP Tracker 2 has 2 DC+ terminals.
There are a total of 6 DC- terminals.

If only one string 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 connec-
max. 36 A to
ting line and bridging wire must be the sa-
a single
me. Bridging the DC terminal is not
DC terminal
necessary because it is bridged internally.

Set MPP TRACKER 2 to "OFF" when star-
ting for the first time (also possible in the ba-
*
sic menu subsequently).
If the Multi MPP Tracker inverter is opera-
D1
ted in Single MPP Tracker mode, the cur-
rents of the connected DC lines are
distributed evenly across both inputs.
Connect the strings separately to the two
MPP Tracker inputs (DC+1/DC+2). The
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 possible in the ba-
sic menu subsequently).
