Characteristics of PV generator
The photovoltaic generator is made
up of strings with differing series
modules numbers.
The photovoltaic generator is made
up of strings which have installation
conditions which are different to
each other.
The photovoltaic generator is made
up of strings with identical series
modules numbers.
The photovoltaic generator is made
up of strings which have the same
installation conditions, that is, all the
strings have the same inclination
angle in relation to the horizontal
plane and the same orientation to
SOUTH.
The photovoltaic generator connected
to each of the inputs has a lower
power than the power limit of the
single input channel AND a maximum
current lower than the current limit of
the single input channel.
(*) The condition is advisable from a system energy production viewpoint, not from the point of view of the
operation of the inverter.

MPPT
A NECESSARY condition for the two MPPT to
MPPT be used independently is that the photovoltaic
generator connected to each of the inputs has
has to be a lower power than the power limit of the single
INDEPENDENT input channel AND a maximum current lower
than the current limit of the single input channel.
A NECESSARY condition for the two MPPT to
be used independently is that the photovoltaic
Possibility generator connected to each of the inputs has
of choosing a lower power than the power limit of the single
between the input channel AND a maximum current lower
than the current limit of the single input channel.
with An ADVISABLE condition (*) in order that the two
INDEPENDENT MPPT may be parallel, is that the photovoltaic
MPPT or generator connected to the two inputs is made
PARALLEL up of strings created from the same number of
modules in series and that all the modules have
the same installation conditions.
A SUFFICIENT condition (*) for the two MPPT
to be used in parallel is that the photovoltaic
generator connected to each of the inputs has a
higher power than the power limit of the single
MPPT input channel OR a maximum current greater
than the current limit of the single input channel.
PARALLEL An ADVISABLE condition (**) in order that the
mandatory two MPPT may be parallel, is that the photovoltaic
generator connected to the two inputs is made
up of strings created from the same number of
modules in series and that all the modules have
the same installation conditions.
