1 Preface
Thank you for choosing inverters from the
coolcept
range of products manufactured by Steca Elek-
tronik 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 (CO2) and other
damaging gases.
Highest efficiency with longer service life
The innovative inverter topology is based on a single-stage transformerless circuit concept and is
integrated into all devices in the coolcept series. This unique technology allows peak efficiencies of
98.0 % or 98.6% to be achieved. Depending on the type, the European efficiency 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.
Designer casing and easy installation
For the first time, the very high efficiency allows the use of a designer casing made of plastic for the
coolcept inverters. This offers many advantages. The overall surface temperature of the devices
remains very low. There are also great installation advantages. The coolcept-x inverters have a sturdy
metal casing that allows them to be also used outdoors.
The lightweight devices weigh only 9 or 12 kg and can be easily and safely mounted on a wall. The
supplied wall bracket and practical recessed grips for right and left handed installers make
mounting of the device simple and convenient. All connections and the DC circuit breaker are exter-
nally accessible.
Visualisation tools and accessories
The devices have a graphical display for visualising the energy yield values, current performance and
operating parameters of the photovoltaic 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.

①Dangerous voltages can remain present on the compo-
nents up to 10 minutes after switching off the DC circuit
breaker and the line circuit breaker.
②Warning. There are 2 voltage sources present: power grid,
solar modules.
③Disconnect both voltage sources from the device before
working on the device: the solar modules via the DC cir-
cuit breaker and the power grid via the line circuit
breaker.
④Read and follow the instructions!

2.4 Proper usage
nThe inverter may only be used in grid-connected photovoltaic systems. The inverter is suitable
for use with all solar modules whose connections do not need to be grounded.
nIn the installation solar modules that have an IEC 61730 Class A rating are required as the
inverter is non-isolated.
nIf the maximum AC mains operating voltage is higher than the photovoltaic array maximum
system voltage then solar modules that have a maximum system voltage rating based upon the
AC mains voltage are required.
Note
An overview of suitable solar modules is available at www.stecasolar.com/matrix.
