1 Preface
Thank you for choosing inverters from the coolceptproduct line of
Steca Elektronik GmbH . By using solar energy, you are making a
significant contribution to environmental protection; by reducing the
amount of carbon dioxide (CO2) and other harmful gases that
burden the earth's atmosphere.
Maximum efficiency with a long service life
The innovative inverter topology is based on a single-stage
transformer-less 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 surface temperatures of the devices overall
remains extremely low. In addition, there are clear benefits for the
installation. 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 externally accessible.
Visualization and accessories
The devices have a graphic display, with which the energy load
values, actual capacities, and operating parameters of the
photovoltaic system can be visualized. The innovative menu offers
the possibility of individual selection of the different measured
values.
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.

2 General information
2.1 General safety instructions
nThis document is part of the product.
nInstall and use the device only after reading and understanding
this document.
nAlways perform the measures described in this document in the
sequence specified.
nKeep this document in a safe place for the entire service life of
the device. Pass the document on to subsequent owners and
operators of the device.
nThe yield of the system can be reduced through improper
operation
nIf the housing is damaged, do not connect the device to the DC
or AC lines
nIf one of the following components is damaged, immediately
take the device out of operation and disconnect it from the
mains grid and PV generators.:
– Device (not functioning, visible damage, smoke,
penetration of liquid etc.)
– Lines
– PV generators
Do not switch the system on again before
– the device has been repaired by a dealer or the
manufacturer,
– Damaged cables or PV generators have been repaired by a
technical specialist.
nNever cover the device
nDo not open the casing: Risk of death. Invalidation of the
guarantee.
nFactory labels and markings must never be altered, removed or
rendered unreadable.
nComply with the instructions of the respective manufacturer
when you connect an external component that is not described
in this document (e.g. external data loggers). Components that
are incorrectly connected can damage the device.

2.4 Intended use
nThe inverter must only be used in grid-coupled photovoltaic
systems. The inverter is suitable for all PV generator with
connections that do not need to be grounded.
nPV generator must be used that have an IEC 61730 class A
rating because the inverter does not have electrical isolation.
nIf the maximum AC operating voltage is higher than the
maximum system voltage of the photovoltaic generator, then
PV generator must be used that have a maximum system
voltage that is higher than the AC grid voltage.
