Steca coolcept3 StecaGrid 3203, Инструкция по установке и эксплуатации

Страница: 4 / 80

1 Preface
Thank you for choosing inverters from the coolcept 3 range of prod-
ucts manufactured by Steca Elektronik GmbH. By using solar energy
you make a significant contribution to environmental protection by
reducing the total amount of atmospheric pollution caused by
carbon dioxide (CO
2
) and other damaging gases.
The innovative inverter topology is based on a single-stage trans-
formerless circuit concept and is integrated into all devices in the
coolcept 3 series. This unique technology allows peak efficiencies of
up to 98,6 % be achieved. Depending on the type, the European effi-
ciency of the devices is also significantly greater than 98 % and sets
new standards in photovoltaic grid-feed systems.
A new and unique cooling concept inside the inverter ensures an
even distribution of heat and a long service life.
For the first time, the very high efficiency allows the use of a
designer casing made of plastic for the coolcept
3
inverters. This
offers many advantages. The overall surface temperature of the
devices remains very low. This also offers great installation advan-
tages. The coolcept
3
-x inverters have a sturdy metal casing that
allows them to be also used outdoors.
The lightweight devices weigh only approx. 12 kg and can be easily
and safely mounted on a wall. The supplied wall bracket and prac-
tical recessed grips for right and left handed installers make
mounting of the device simple and convenient. All connections and
the DC circuit breaker are externally accessible.
The devices have a graphical display for visualising the energy yield
values, current performance and operating parameters of the photo-
voltaic system. Its innovative menu allows individual selection of the
various measurements.
See www.stecasolar.com for further information on accessories. Your
installer can, of course, also give you more information about the
options and accessories that are available.
