(PVI-10.0/12.0-I-OUTD(-S)-400 Rev:1.3)
WARNING: To prevent damage to equipment, the string voltage must
never exceed 520 Vdc. Due to the negative thermal coefficient of the
open circuit voltage of the photovoltaic module, maximum voltage is
obtained in conditions of minimum ambient temperature. It is advised to
check the configuration of the photovoltaic generator by means of the
AURORA Designer dimensioning software.
NOTE: A minimum Vstart input voltage of 200 Vdc (voltage can be set
from the control panel within a range of 120 Vdc to 350 Vdc) is required
in order to start the AURORA grid connection sequence. Once
connected, AURORA will transfer the available power to the grid, for
any Vdc input voltage value within the range between 70% of the value
set for Vstart, and 520V. The power transferred for each array is also
limited by the maximum manageable current (see section below) (Fig
.
29 and Fig
.
30 show the limits for which maximum power is
transferred).
The current of each array must also fall within the limits of the inverter. For
AURORA, the maximum current coming from each input can be 24Adc for PVI-
10.0-I, or 25 Adc for PVI-12.0-I. The PVI-10.0/12.0-I-OUTD AURORA models
can be used each for two different arrays.
In the event that the photovoltaic system exceeds the capacity of a single inverter,
other AURORA inverters can be added to the system. Each of these inverters will
be connected to an adequate section of the photovoltaic field on the DC side, and
will be connected to the distribution grid on the AC side.
Every AURORA inverter will work independently from the others, and, from its
section of photovoltaic panel, will supply the grid with the maximum available
power.
Decisions regarding the structuring of a photovoltaic system depend on a certain
number of factors and considerations, including the type of panels, the availability
of space, the future location of the plant, long-term energy production targets, etc.
