Fronius Primo 3.0-1 Installation Instructions

Single MPP tracker mode on an inverter with multiple MPP trackers:
Connecting multiple interconnected solar mod-
ule fields to an inverter with multiple MPP track-
ers using one lead
If the strings are connected using a
string collection box and only one bus
is used for connection to the inverter,
the connection DC+1 (pin 2) and DC+2
(pin 1) must be jumpered.
The cable cross-section of the DC con-
nection lead and the jumpering must
be the same. Jumpering of the DC-
terminal is not necessary, as these ter-
minals are jumpered internally.
When starting for the first time, set
MPP TRACKER 2 to "OFF" (this can
also be done later in the Basic menu).
If the inverter with multiple MPP
trackers is operated in single MPP
tracker mode, the currents from the
connected DC leads are divided evenly
across both inputs.
Single MPP tracker mode with only one string on an inverter with multiple MPP
trackers:
Connecting only one string to an inverter with
multiple MPP trackers
If only one string is used for connec-
tion to the inverter, the connection DC
+1 (pin 2) and DC+2 (pin 1) must be
jumpered.
The cable cross-section of the DC con-
nection lead and the jumpering must
be the same. Jumpering of the DC-
terminal is not necessary, as these ter-
minals are jumpered internally.
When starting for the first time, set
MPP TRACKER 2 to "OFF" (this can
also be done later in the Basic menu).
If the inverter with multiple MPP
trackers is operated in single MPP
tracker mode, the currents from the
connected DC leads are divided evenly
across both inputs.
