About these instructions
The Abbreviated Installation Instructions provide the
installer with information on mounting, connecting
and commissioning the device.
The Abbreviated Operating Instructions contain
basic device operating information for the operator.
Detailed information is provided in the comprehen-
sive Installation and Operating Instructions, available
via the Internet.
Other sources of information are specified via Internet addresses and QR codes. Scan the
QR codes using a smartphone and suitable QR code app.

Intended use
 The coolcept family of products consists of inverters of different power classes, intended for indoor
or outdoor installation and for single-phase or three-phase feeding.
 These inverters may only be used in grid-connected photovoltaic systems.
 The inverter is suitable for use with all solar modules whose connections are not grounded.
 All connected solar modules must be classified as Class A according to IEC 61730, because these
inverters do not have galvanic isolation.
 The maximum permissible system voltage of the photovoltaic generator must be higher than the
AC grid voltage.
 Connections for an optional energy storage system are provided on some models. The connector
must never be connected directly to a battery.

Safety
 This document must be read and understood in full before installing and/or using the de-
vice.
 Connection, commissioning and repair may only be performed by a qualified electrician
who is specially trained in solar technology.
 If one of the following components is damaged, immediately take the device out of operation and
disconnect it from the grid and solar modules:
- Device (not functioning, visible damage, smoke, penetration of liquid etc.)
- Cables
- Solar modules
 Do not switch on the system again until it has been repaired and checked by a suitably qualified and
authorised technical specialist.
 Dangerous voltages can remain present on the components up to 10 minutes after switching off the
DC circuit breaker and the line circuit breaker.
 Attention, there are 2 voltage sources present: the power grid and the solar modules.
Disconnect both voltage sources from the device before working on the device.
 Do not cover the device.
 The factory-applied labels on the device must not be modified or removed.
 Do not open the device.
 Keep children away from photovoltaic systems.
 Follow the general and national safety and accident prevention regulations.
 This document must be stored safely and be available for the entire service life of the device and
must be passed on to any subsequent user.
Signs and labels on the device
1 Type plate with the main technical data and serial number
2 Safety label with warning notices
When connecting external components (e.g. data logger): be sure to observe the
manufacturer’s instructions. Incorrectly connected components can damage the
device.
Incorrect operation or settings, especially during the initial commissioning proc-
ess, can reduce the yields of the system

Installation
 Ensure that you do not impair the fire safety measures of the building when routing ca-
bles for the device.
 Make sure that no inflammable gases are present.
 Observe all applicable installation regulations and standards, national laws and connection values
specified by the regional power supply company.
 Risk of death by electrocution!
- Switch off all AC line circuit breakers and secure them against being unintentionally switched on
again.
- Check that all pins of the AC cable are free of voltage.
- Set the DC circuit breaker on the inverter to position 0 and secure it against being unintentionally
switched on again.
- DC cables carry voltage when the solar modules are subjected to sunlight.
The mounting location and immediate environment must be: permanently fixed, vertical, flat, non-
inflammable and not subject to constant vibration. The mounting surface must be able to securely hold
the fastening screws.
Ensure conformance to the permissible ambient conditions.
Do not install the inverter in areas where animals are kept.
Observe the connection ratings specified on the type plate.
Lay the cables such that the connection cannot come loose accidentally.
Do not connect the DC cables to an earth potential.
a. Connect the AC plug to the grid cable as
shown (view of the cable connections).

b. Connect the DC plugs to the cables to the
photovoltaic generator, observing the correct
polarity.

c. If present, plug in the TCP-IP (1) and Modbus RTU (7) data connections.
d. If present, plug in the RS485 (2) data connection. Plug in any termination plugs that may be re-
quired.
e. coolcept-x and coolcept³-x only: close any open RJ45 sockets (1, 2) with the sealing caps provided.
f. Press the cable plugs of the photovoltaic generator into the PV connectors (4, 5) on the inverter
(they click audibly into place).
g. Only in the case of coolcept³, only if power converter SolUse is present: press cable plugs of the
power converter SolUse into BAT connections (8, 9) on the inverter (they click audibly into place). It
is not allowed to connect a photovoltaic generator to the BAT connections.
h. Plug the AC plug into the coupling (3) on the inverter (this clicks audibly into place).
i. Switch on the AC circuit breaker. This switches on the inverter. The display shows the start page for
initial commissioning. Initial commissioning starts. A number of basic settings are queried in a pre-
defined sequence.
Detailed information on installation of the AC cables and the line circuit breaker is pro-
vided in the downloadable version of the Operating Instructions.

j. Set the display language.
k. Set the date/time.
l. Set the country of use. Attention, the country can only be set once!
For detailed information on the country settings, see:
http://www.steca.com/Wechselrichter-Wohnsiedlung
Additional configuration may need to be entered, depending on the selected country.
m. Select Finish and press SET.
n. If the settings are incomplete then a dialogue stating Settings are incomplete is displayed.
Press SET and complete the missing basic settings.
o. When all settings have been made, a dialogue stating Are all settings correct? is dis-
played. To correct any settings: press ESC. To finish initial commissioning: press SET for a longer
period of time (> 1 s). If SET was pressed for a longer time then the inverter starts anew and syn-
chronises itself with the grid.
p. Switch on the DC circuit breaker (6) on the underside of the inverter.
The inverter is ready for operation.
In the case of questions or if more installation information is required, please refer to the
full Operating Instructions, which are available for download.
