PV generator characteristics
The photovoltaic generator consists
of strings having a different number
of modules in series from each other.
The photovoltaic generator consists
of strings that have different installa-
tion conditions from each other.
The photovoltaic generator consists
of strings having the same number
of modules in series as each other.
The photovoltaic generator consists
of strings that have the same instal-
lation conditions, that is to say, all
the strings have the same inclination
from the horizontal and the same
orientation to the SOUTH.
The photovoltaic generator con-
nected to each of the inputs has a
power lower than the power limit
of the input channel AND a current
lower than the current limit of the
input channel.
(*) This condition is advisable from the point of view of the energy production of the system, not from the
point of view of inverter operation.

The photovoltaic generator con-
nected to each of the inputs has a
power higher than the power limit
of the input channel OR a current
higher than the current limit of the
input channel.
(*) This condition is sufficient from the point of view of the energy production of the system, not from the point
of view of inverter operation.

point of view of inverter operation.

Notes
A NECESSARY condition so that the
three MPPTs can be used in independent
mode is for the photovoltaic generator
connected to each of the inputs to have
a power lower than the power limit of the
single input channel AND a maximum
current lower than the current limit of the
single input channel.
A NECESSARY condition so that the
three MPPTs can be used in independent
mode is for the photovoltaic generator
connected to each of the inputs to have
a power lower than the power limit of the
input channel AND a maximum current
lower than the current limit of the input
channel.
An ADVISABLE (*) condition so that
the three MPPTs can be connected in
parallel is for the photovoltaic generator
connected to the three inputs to consist
of strings made by the same number of
modules in series and for all the modules
to have the same installation conditions.
A SUFFICIENT (*) condition so that the
three MPPTs must be used in parallel
mode is for the photovoltaic generator
connected to each of the inputs to have a
power higher than the power limit of the
single input channel OR a maximum cur-
rent higher than the current limit of the
single input channel.
An ADVISABLE (**) condition so that
the three MPPTs can be connected in
parallel is for the photovoltaic generator
connected to the three inputs to consist
of strings made by the same number of
modules in series and for all the modules
to have the same installation conditions.
