Connection with independent channels

WARNING:
connection/disconnection procedure detailed in paragraph 3.4.1.
WARNING: The conditions which are NECESSARY to put in operation the
two MPPT in the indipendent modality are the following:
- The photovoltaic generator connected to each of two inputs, must
provide the current (14 Adc for PVI-4.6-OUTD, 12.5 for PVI-3.8-I-
OUTD) and the maximum power LESS than the limit of current and
power of the singular input channel (3KW).
- Negative pole of the photovoltaic generator must be grounded
(Grounding of DC inputs, Par. 3.4.9)
In order to configure AURORA with independent channels, remove the jumpers
between the positive and negative terminals in
Fig. , and move the selector switch in
10
Fig. to the "IND" position.

3.4.5.2

Parallel connection of channels

WARNING:
connection/disconnection procedure detailed in paragraph 3.4.1.
Use this configuration when the input current to one of the channels is greater than
14Adc (PVI-4.6-I-OUTD) or 12.5Adc (PVI-3.8-I-OUTD), when the input power to
one of the channels is greater than 3kW, when the positive pole of the photovoltaic
generator has been grounded (positive Grounding, Grounding of DC inputs, Par. 3.4.9)
or when none of two poles of the photovoltaic generator has been grounded (floating
photovoltaic generator, Grounding of DC inputs, Par 3.4.9).
Parallel configuration is the factory setting therefore, it is not necessary to change the
connections.
