Eco inverter
Single MPP tracker mode on the MPP tracker input
If the solar module strings are connected to a string combiner box (GAK for
short - generator connection box) and the distance to the inverter is bridged by
means of a DC string, this DC string can be connected to the inverter as follows.

DC Con Kit 25
The Fronius DC Con Kit 25 (4,251,015) can be used to connect a solar module
string with a cross-section of up to 25 mm² to the inverter.
Connecting multiple interconnected solar mod-
ule fields to an inverter with multiple MPP track-
ers using one lead
By using the DC Con Kit 25, the DC
strings of the connected DC lines are
equally distributed to both inputs.
