Inverter DC con-
nection
The inverter is designed to be connected
and used exclusively in conjunction with
ungrounded solar modules.
The solar modules may either be grounded
on the positive or negative pole.
Only break out as many target break points as the number of cables that are provided (e.g.
if there are two DC cables, then break out two recesses).
IMPORTANT! Check the polarity and voltage of the solar module strings.
If DC cables are laid over the shaft of the
DC main switch or across the connection
block of the DC main switch, they may be
damaged when the inverter is swung in or
they may even prevent the inverter from
being swung in.
IMPORTANT! Do not lay DC cables over
the shaft of the DC main switch or across
the connection block of the DC main switch.
Multi MPP tracker
inverters - Froni-
us Primo 3.0 - 8.2
In the case of inverters with multiple MPP trackers, there are two independent DC inputs
(MPP trackers) available. These can be connected to an unequal number of solar modules.
There are two terminals for DC+ available per MPP tracker. In total there are four terminals
for DC-.
Connecting two to four strings in multiple MPP tracker mode:
