Renewable Energy Technologies
uninterrupted electricity supply represents a key competence in the 21st century.
photovoltaics (pv) and fuel cells in particular are of special importance because
of their sustainability and environmentally friendly technology. in contrast to water
and wind power, however, these sources produce Dc voltage which, in order to
be used commercially, must first be converted to ac voltage at the appropriate
line frequency (50 or 60 Hz).
Tasks
photovoltaic systems and other renewable energy technologies work on a similar
principle. Through chemical or physical processes, energy that is already there is
transformed into electric energy. This electric energy is then processed and made
available in a standardized form (see diagram on page 6). The electricity gener-
ated by such a system, however, must be used immediately, at the same time
that it is generated. and that is why there is the need for a storage medium which
can hold energy when there is no immediate consumption. Where electricity is
fed into the grid, the utility company will take on this task by constantly readjust-
ing the inflow of energy produced by third parties along with the fluctuation in
overall energy demand.
Such systems basically require two interconnected subsystems: the power
system, which makes the energy generated available in a grid-compliant form,
and the control system, which ensures – and monitors – the reliable and safe
operation under power.

3 | ASO/FSO
The quick-acting ASO line fuse
is designed for DC applications
of up to 1000 VDC and is capa-
ble of safely breaking nominal
currents of up to 30 A, making it perfectly suitable for
short-circuit protection in the individual lines of PV systems.
FSO, the matching touch-proof fuseholder, is designed for
DIN rail assembly and therefore perfectly suitable for use in
junction boxes.
7 | 10 | 11 | AVTS, AVTP, AVTT
The connection between the
solar generator and the trans-
former/inverter stage inside a
building is governed by the VDE
0185 lightning protection standard which specifies that
all power and data lines must be protected against power
surges. SCHURTER provides the suitable surge protection
components.
10 | ISR
Pulse transformers such as
ISR are used for reliably control-
ling power transistors and for
converting measured values,
galvanically isolated, from the power circuit to signals in the
control circuit, in order for it to be able to derive from the
power circuit the necessary parameters for controlling the
solar inverter.
10 | Touch Panel Unit
A solar inverter, like any other in-
verter, needs to be parametrized
using the appropriate system
parameters. The Touch panel is
an easy-to-use input medium highly suitable for this task.
Touch panels with a sealed membrane are impervious to
dirt and liquids, therefore easy to clean and hence perfectly
suitable for use in harsh environments.
11 | SHT 6.3x32
Circuits must be protected with
fuse-links against short circuit if
separate electronic modules are
used. E.g. The prallel switched
outputs of inverters are protected with fuses of the type
SHT 6.3 x 32 mm.
12 | FMAC ECO, FMAD, FMBC
NEO, FMBD NEO…
The DC voltage generated by PV
systems is converted to stand-
ardized AC line voltage using
frequency inverters or solar inverters which reassemble the
maximum solar energy supplied at the correct line fre-
quency (50 or 60 Hz) and amplitude (250 or 380 VAC). The
conversion process, however, causes interference which
makes it more difficult to comply with the line quality as
specified by the law. This is where SCHURTER individual
components or entire AC filters prove remedial. For off-
grid systems, sinusoidal filters are also suitable.
8 | FMER SOL
This DC filter reduces interfer-
ence caused by energy conver-
sion due to the solar panels’
long connecting lines. It reduces
interference to a minimum, thereby considerably increas-
ing installation life span and safety. The type FMER SOL
filters are suitable for voltages up to 1200 VDC at nominal
currents of between 25 A and 1500 A, i.e. for small off-grid
systems as well as for power plants of up to 500 kVA.
9 | 10 | 11 | FUL, FEC, FUA, FUP,
OGD, OGD-SMD…
Protection against short-circuits
and harmful residual currents
in electric appliances must be
ensured during maintenance as well. For such purposes,
SCHURTER offers various fuse mounting designs featuring
open and shock fuseholders with built-in touch protection
and various IP ratings.
10 | DLF, DFKF
Linear chokes such as DLF are
used for smoothing out output
voltage fluctuations in step-
up/down transformers, while
current-compensated chokes such as DFKF are used for
attenuating electromagnetic interference in auxiliary power
supplies.
