1.0 Product Description
1.1 Proper use
1.2 Function description
The Sunways AT Solar Inverter is the link
between your solar generator and the
public power grid. The energy from the
connected solar generator is converted to
grid-conformant AC current and fed into
the grid.
Conversion from direct into alternating
current
The AT Solar Inverter converts the direct
current produced by the solar generator
into alternating current. The alternating
current is then fed into the public power
grid.
Thanks to the HERIC® topology with FP
switching, the AT Solar Inverter has a
voltage curve which corresponds to that
of a transformer unit with an earthed
negative terminal, and is generally also
recognized for operation on thin-film
modules.
Operating and display elements
Various interfaces are available for system configuration and monitoring:
· Operating field (LCD display and keyboard) for displaying operating and
status values or for inputting system
parameters
Solar modules which require earthing of
the positive terminal cannot be operated
with the AT Solar Inverter. If in doubt,
always ask your module manufacturer
about a release!
· Operating LED
· Integrated web server for display and
configuration via a web browser
Interfaces
· Bus interface for connecting an
analogue modem, ISDN modem or
GSM/GPRS modem
· Ethernet interface for connecting a PC
or for integration in existing networks
· CAN bus interface for interconnecting
several solar inverters
Design of solar inverter
The principle design of the AT Solar Inverters can be recognised from the block
diagram. The most important characteristic of the inverter is the earthing of the
solar generator, i.e. the negative terminal
is directly connected to the neutral conductor on the grid.
The solar generator voltage connected to
the inverter input is always positive and is
initially adapted by the DC actuator and
then converted to alternating current by
the high-efficiency HERIC® inverter. The
AC connection is made with 5 wires for a
3-phase feed point (3-phase AC current
connection) due to the 3-phase passive
grid monitoring, whereby feeding is
only single-phase. A 3-wire connection
is made at the single-phase feed point
(alternating current connection).
· S0 pulse output for controlling large
displays
· Alarm relay for realising simple monitoring locally
· Interface for connecting an irradiation
and temperature sensor
Data logging
The AT Solar Inverter is equipped with
internal data logging for recording and
saving system data:
· 5-minute mean values of voltages,
currents, output, temperature and irradiation (if sensor is installed)
· 5-minute, daily, monthly and annual
values of energy yield
· Memory for malfunction messages
Grid monitoring
The AT Solar Inverter assumes the task
of grid monitoring for the protection of
the unit and persons. In case of abnormal
grid conditions, feeding is immediately
interrupted and the solar inverter disconnects from the grid by triggering the grid
relay. 10

· Check your solar generator approx.
every three years for soiling. This occurs especially on the lower edge of
the modules and forms a veil that cannot be washed off even by heavy rain.
Reduced yield can be prevented by
cleaning with a wet cloth or a brush.
1.3 Integration in solar system
Design of solar generator
The technical data of the selected solar
generator must be within the solar
inverter‘s specifications (see Technical
Data). Incorrect dimensioning can lead to
reductions in the yield and to destruction
of the unit.
· Avoid switching off individual modules
or solar cells of your system. This can
lead to major decreases in yield.
The Sunways design program Sundim
may be helpful to you. Sunways Sundim
is available on the included CD-ROM or
at our homepage www.sunways.de.
Be sure to take the following points into
account before planning your system:
· Watch the celestial alignment of the
modules. A maximum yield is achieved
in Central Europe with a module slope
of 30° to the vertical and direction of
the solar generator field directly to the
south.
· The output of the cells decreases as
the module temperature increases.
Install your solar generator with sufficient ventilation from behind.

25
3.2 Electrical installation
Check using the rating plate on the solar
inverter whether it is approved for the
maximum solar generator voltage.
Solar generator connection
The positive and negative lines must be
kept electrically separate from the earth
potential.
!
Extreme danger from electric shock!
Touchable, live parts of the solar generator (e.g. metal frame, carrying structure,
etc.) must be earthed (connection with
PE).
Touching live parts can result in death.
All electrical work must be conducted by
a qualified electrician while observing
the VDE regulations, national and other
regulations!
Check the solar generator against shortcircuits to earth.
Before connecting the solar generator to
the solar inverter, the integrated DC load
break switch must be opened quickly
(position 0).
Execute the direct current wiring in accordance with the system dimensioning
of your planning expert.
Prepare all solar generator cables before
you carry out the connection of the solar
generator to the solar inverter.
After the PV solar generator is connected
to the solar inverter and the DC load
break switch is switched on, the direct
generator voltage is present internally.
Check each solar generator string for
proper operation with an open-circuit
voltage and short-circuit current measurement.
The connectors may not be separated
while under load.
26
Always separate the solar generator
side first by quickly opening the DC load
break switch and then the grid connection by switching off the corresponding
mains fuse.
The solar generator strings must be identically dimensioned and comply with the
specifications of the solar inverter.
No external DC load break switch is
required. A DC load break switch as required in accordance with DIN VDE 0100712 is integrated in the solar inverter.

Tyco Solarlok plug-in connection system
The Solarlok plug-in connection system is
used for the simple, reliable connection
of individual solar generators up to the
solar inverter.
The neutral connector can be used to
connect both positively and negatively
coded sockets.
Components
The following connectors are used:
Installation
!
· Positively coded connector
Extreme danger from electric shock!
Touching live parts can result in death.
· Negatively coded connector
All electrical work must be conducted by
a qualified electrician while observing
the VDE regulations, national and other
regulations!
· Neutral connector
Tyco Solarlok connectors are only reliable
for connection on permanently installed
lines.
Only the Tyco-Solarlok hand crimping pliers may be used to crimp the connectors.
28
Various circular contacts are used for
different conductor cross-sections with
the Tyco Solarlok connectors. The correct
tool insert must be used in accordance
with this cross-section. The included Tyco
Solarlok connectors are equipped with
circular contacts for a cable cross-section
of 4 mm² to 6 mm².
The seals and clamping baskets used in
the preassembled connectors are approved for cable sheath diameters from
4.5 mm to 6.9 mm. Special seals and
clamping baskets must be used for cables
with a sheath diameter greater than 6.9 mm.
During preassembly, the connectors must
be separated from all other voltage
sources.
The connectors may not be separated
while under load. The circuit must be
opened at a suitable point for this purpose.
Provide the lines with corresponding
stickers as close as possible to the connectors to prevent confusion.
Any kind of soiling (dust, moisture, etc.)
has a negative effect on the connector
system with regard to function over the
intended period of use. This particularly
applies to the suitability for use of the
seals and the crimping of the contacts.
Therefore, extreme care must be taken
to achieve proper processing during assembly.
The Tyco Solarlok hand crimping pliers
can be purchased from your sales partner.
29
The following sequence must be observed during assembly:
Handling
The positively/negatively coded connectors are marked with polarity symbols
and a coloured ring (blue = negative,
red = positive). They are equipped with
coding ribs for assignment, which ensures
that only connectors of the same polarity
can be connected to each other.
1. Stripping the voltage-free line.

Grid connection
If the voltage on the AC connection exceeds the permissible value due to a long
line length or an insufficient cable crosssection, the solar inverter will disconnected from the grid. In power grids with
a low output and a high solar generator
output, this can lead to individual solar
inverters being switched off and then on
again several times.
!
Extreme danger from electric shock!
Touching live parts can result in death.
All electrical work must be conducted by
a qualified electrician while observing
the VDE regulations, national and other
regulations!
Survey
The grid connection of the solar inverter
is made via an AC bayonet connector on
the underside of the unit. With a 3-phase
feed point (3-phase AC connection), a 5wire connection (L1, L2, L3, N, PE) is used
due to the 3-phase passive grid monitoring, while only a 3-wire connection (L1,
N, PE) is used on the single-phase feed
point. Feeding is always single-phase via
AC terminal 2.
Observe the pin assignment of the AC
bayonet connector. An incorrect assignment can result in the unit being destroyed.
No consumers may be connected to the
supply line from the solar inverter to the
mains fuse.
Always separate the solar generator
side first by quickly opening the DC load
break switch and then the grid connection by switching off the corresponding
mains fuse.

Depending on the grid operator and
the feed point, a three-phase meter or a
single-phase meter must be used.
The solar inverter always only feeds via
AC terminal 2. If several solar inverters
are operated in parallel in a 3-phase grid,
AC terminal 2 of the unit must be distributed uniformly among the grid phases
L1, L2 and L3 to avoid unequal loading.
Some grid operators require the use of a
reverse-current-capable meter.
A basic distinction is made between two
different connection options of the solar
inverter to the public power grid:
· 3-phase AC grid
(e.g. Germany)
· 1-phase AC grid (e.g. Italy, Spain)
!
CAUTION
Observe the regional regulations for the
grid connection.
In Germany the grid connection must
always be 3-phase!

Networking solar inverters via RS485 interface
If you want to monitor a solar system
with Sunways Solar Inverters both the NT
series and the AT series together, then
you can use the RS485 interface integrated in the solar inverters for this purpose.
This function is supported from AT Communication Software Version 2.0002. If
necessary, carry out a software update
(see the chapter Software Update). The
system networked with the RS485 interface can be monitored with the Sunways
Communicator.
Use a twisted two-wire cable to network
the solar inverters with each other.
Mount the terminating resistor on the
last solar inverter.

S0 interface
The S0 pulse output enables, for example, the connection of a large display
(Sunways Display) for displaying the
momentary output, the energy yields and
the CO2 reduction.
S0 interface with large display
You can use the S0 interface on the main
unit if you want to transmit the entire
line yields as a sum to a large display.
The S0 interface is adjusted via the
display on the inverter. Go to the menu
«Settings – Network – Interfaces». Please note that the maximum pulse rate
may not be greater than 15 pulses/sec.
Calculate the pulse rate depending on
the size of the solar system using the following formula:
Pulse rate [pulses/kWh] =
50,000/system size [kWp]
The pulse rate must be set on your solar
inverter and on the large display.
42
Connection of temperature and irradiation sensor
The optional addition of an irradiation
sensor (model Si-01TC-K from Ingenieurbüro Mencke & Tegtmeyer) with an
integrated PT-100 temperature sensor for
temperature measurement enables the
acquisition of irradiation data and the
corresponding module temperature and
storage in the internal data memory as
a 5-minute mean value. This additional
measuring unit helps analyse the system
output. Based on the values, any errors
on the PV generator, e.g. shading or failure of solar cells, can be detected.

Connecting alarm relay
The solar inverters are equipped with a
potential-free alarm relay as standard.
The relay can be designed as a makecontact element or as a break-contact
element and is actuated for all malfunctions signalled by the device. This ensures
a faster, more reliable indication of a
possible fault in the PV system on site.
For PV systems with several solar inverters, the individual relays can be switched
in parallel and connected via a common
indicator lamp.
The main unit also signals faults from
other units in the CAN network via the
alarm relay. It is therefore sufficient for
simple alerting to connect the alarm
relay of the main unit.
!
CAUTION
The connected signalling unit must be
fused separately! The terminals are intended for a cable cross-section of 0.2 mm2 to 1.5 mm2.
44
When dimensioning the cross-section,
also take the current consumption of the
connected signalling unit into account!

6.0 System monitoring
96
6.1 General information
One of the four possible connections
between a PC and the solar inverter is
possible for this purpose:
The basis for the system monitoring is the
data logger integrated in the AT solar
inverter. The solar inverters of the AT series are equipped with a broad range of
monitoring options for your solar system:
· Direct connection via an Ethernet
cable
· The Sunways Browser offers the display of instantaneous values, stored
operating data and settings
· Connection via an existing Ethernet
network
· Connection via the Internet, e.g. connection of the solar inverter to a DSL
connection
· With active alerting the main unit can
send errors which have occurred in the
solar system to a selected recipient by
Email.
· Connection via the Sunways Modem
· With the Sunways Portal connection
the AT solar inverter can send the
operating data of your solar system to
the Sunways Portal daily without additional hardware. This enables you to
track your yields via the Internet.
97
6.2 Integrated data logger
Operating Data (5-Min. Mean Values)
The integrated data logger of the AT
solar inverter stores the operating data
of your solar system. In addition to 5minute mean values, energy yields are
also stored as 5-minute, daily, weekly,
monthly and annual values. Up to 200
status changes (warnings and errors with
start and end) are also stored. Each data
record contains the data and time. The
data logger is designed as a circulating
memory, i.e. the respective oldest data
are overwritten with new data.

6.12 Active alerting
General information
With active alerting you are informed
of status messages (errors and warnings)
in your solar system by Email. If a status
message was active for longer than 15
minutes or occurred 5 times in one day,
then you will receive an Email at the next
full hour, which is sent to the Email address stored in the solar inverter.
The main unit sends the status messages
of all solar inverters if they are CAN-networked.
Requirements:
· Communication software at least Version 2.0002
· A connection of the main unit via a
network or modem must be established.
· When dialling in via modem, the correct dial-in settings must be stored (see
Internet dial-in via modem).
· Correct Email settings must be stored
in the Sunways Browser (see «Email
settings»)
124
Alerting settings
The alerting settings can be accessed with
the button «Settings – System Monitoring» in the «Active Alerting» section.
Function buttons

alerting function.
Email address
In the «Email address» field you enter the
Email address to which the messages are
to be sent.

6.13 Sunways portal connection
General information
You can have the operating data of your
solar system automatically sent to the
Sunways Portal to monitor your system
via the Internet. This is possible without
using a Sunways Communicator.
The portal connection is configured via
the Sunways Browser. Following activation a registration Email is automatically
sent to the Sunways Portal by the main
unit which contains the system data, e.g.
number of units, serial number, etc.
From the activation, the operating data
of the day are sent to the Sunways Portal
by Email daily before the main unit is
switched off for the night. The interval
can also be set shorter as an alternative.
If a change is made to your solar system
(e.g. additional unit), then the change is
automatically reported to the Sunways
Portal.
A basis access for the Sunways Portal for
displaying the yield data is available to
every Sunways customer free of charge.
Expanded functions, e.g. the rated/actual
comparison in the Sunways Portal, can be
purchased for a fee. Requirements: · Communication software at least Version 2.0002
· A connection of the main unit via a
network or modem must be established.
· When dialling in via modem, the correct dial-in settings must be stored (see
Internet dial-in via modem).
· Correct Email settings must be stored
in the Sunways Browser (see «Email
settings»)
· Correct portal settings must be stored
in the Sunways Browser.

Setup
Check whether you meet all requirements. Configure the specified settings if
necessary.
Open the setting page in the Sunways
Browser. This can be accessed under «Settings – System Monitoring» in the section
«Sunways Portal».
Portal connection
Activation or deactivation of the portal
connection.
Portal address
Preset for the Sunways Portal
Mailbox file
Preset for the Sunways Portal
System ID
System ID assigned by the portal. This is
automatically entered following the portal activation of the solar inverter.
Portal Email
Preset for the Sunways Portal. Here as
well, you can enter another address if
you want to evaluate the operating data
yourself.
Email interval
Select the Email interval. If you operate
the system on a DSL modem, you can
set a short interval. If you use a modem
connection, select a longer interval (e.g.
daily) to eliminate unnecessary telephone
costs
127
User Email
In this field you must enter an Email
address to which the confirmation Email
is sent by the portal. It contains a link
for the activation of your system in the
Sunways Portal.
User SMS
As an option you can specify an SMS
number here to which an SMS message is
sent after your system is successfully set
up in the portal.
The settings are saved in the solar
inverter with «Send».
To view your system data in the Sunways
Portal, you require a user account. This
will be issued to you if you follow the
link in the confirmation email and fill out
the registration form. As an alternative
you can also enter an existing user name
with the correct password to assign the
system to an existing user account.
Function buttons
With «Portal Test» you can test the portal
connection. You receive an Email at the
address in the field «User Email» and
an SMS if you have entered your mobile
phone number in the field «User SMS».
Before the portal test you must transmit
the settings to your solar inverter with
«Transmit». If the test was successful, a
message is sent to the user Email address
or the user SMS address.
