The
RPS450
solar
inverters
represent
the
optimal
solution
for
feeding
the
solar
energy
converted
from
solar
modules
into the
electrical
supply
grid. A
high
MPPT
adaption
efficiency
as well
as the
use of
high-quality
and low-loss
components
ensures
the
highest
efficiency.
The use
of
sophisticated
and
robust
standard
components,
which
have
already
been
used
thousands
of times
in
electrical
propulsion
technology,
and are
proven
under
the
harshest
environmental
conditions
all over
the
world,
guarantees
a long
life-cycle
and high
reliability.
The high
availability,
paired
with the
excellent
efficiency
leads to
maximum
outputs.
A
modular
system
configuration
with a
few
easily
accessible
individual
parts
allows
the most
effective
and
shortest
amount
of
service
and
maintenance
work.
The wide
input
voltage
range
allows
high
flexibility
in the
planning
of the
solar
generator.
The
parameters
of the
RPS450
solar
inverters
are set
by
default
at the
factory
so that
they can
be
operated
immediately
with any
generator
configuration.
This
allows
fast and
therefore
good-value
commissioning.

RPS450 - Compact -
For power ranges up to 170kWp, Bonfiglioli offers the RPS450 solar inverter with an internal trans-former for feeding into the low-voltage network. Galvanic isolation, which is compulsory in many countries, between the power supply and the generator in order to prevent the feeding of constant components is guaranteed by the internal isolating transformers.
The compact units of the RPS450 range can be interconnected as often as desired on the power supply side, which makes it possible to implement large systems and permits a flexible adjustment on the solar generator.
RPS450TL -Modular -
In the power range from 280kWp to 1190kWp, Bonfiglioli offers solar inverters of the RPS450-TL range without internal transformers. This is the most cost and yield optimal solution for photovoltaic systems of moderate to large output. The modular construction allows a perfect adjustment of the inverter to the respective solar generator and increases the availability of the system. The right size of inverter can be selected from the pre-defined and cost-optimised combinations. Overall systems of up to 1.19 MWp can be flexibly constructed from individual inverter modules, with nominal outputs of 140kWp and 170kWp. The RPS450TL solar inverters are designed for IT networks and can be attached directly to the low-voltage connections of the medium-voltage transformers. Network connection modules serve as an interface between the inverter modules. Additional low-voltage distribution boards are therefore not necessary.
Each inverter module possesses its own MPP tracker, which reduces yield losses caused by the mismatching of the solar generator.
