The direct current generated in the solar modules can be fed into the
public mains network or put to home use after having been transformed in
an inverter.
This is the basic purpose of your FRONIUS IG unit. Electricity is
converted
under the roof
In a parallel connection of several
such strings the potential output
and the modular electric power will
increase, while the voltage will
remain unchanged. The total of all
solar modules connected parallel
and in series is called solar genera-
tor.

module 1
Power output and voltage are
increased by combining a number
of solar cells. If solar modules are
connected in series like on a string,
both the output potential as well as
the voltage will increase.
