Thank you for having chosen a Sunways
Solar Inverter NT 10000! You have acquired
a high-quality product with unique features
and a top efficiency level. This Solar Inverter
is designed in accordance with the proven
HERIC®topology and therefore guarantees
you a maximum energy yield.
The Solar Inverter is equipped with three
independent energy units which transform
the energy of three separately connected
PV generators into grid-compatible AC
power and inject it in three phases. Thanks
to the MPP multitracking process, PV gene-
rators with various ratings can be connected
to the same Solar Inverter with the
NT 10000.
In this user manual, you will find explana-
tions on how to use the Sunways Solar
Inverter NT 10000. It includes information
on installation, commissioning, the functio-
ning method, and system monitoring.

General Safety Instructions
All safety instructions contained in this
section as well as in the entire user manu-
al must be observed to ensure the safety
of the user. The described product may
not be operated if any mechanical or elec-
trical component is defect.
Prior to commissioning the PV system, we
strongly recommend reading and observing
the manual and the instructions carefully!
Non-compliance may lead to serious con-
sequences such as damage to the device,
damage to other assets, personal injury, or
fatal accidents.
The Solar Inverter may only be installed
by a trained and qualified electrician.
It must be approved by the power supply
company in charge. In the chapter
headings, the due steps are additionally
marked by the adjacent symbol.
1.1 Safety Instructions
The user manual contains safety instruc-
tions. They are marked by a triangle with
an exclamation mark.

Opening the Device
Prior to opening the housing, always
disconnect the device from the grid and
the PV generator.
After having been disconnected from the
PV generator, there is still lethal voltage
inside the device and at the PV generator
hubs for approximately five minutes. It
takes that long for the energy-storing
capacitors to fully discharge.
After having disconnected the device
from the grid and the PV generator, wait
at least five minutes before opening the
device.

Checking the Consignment
Prior to shipment, our products are chec-
ked to make sure they are in a perfect con-
dition. They are carefully packaged in recy-
clable materials. Nevertheless, damage may
occur during transportation which is nor-
mally the fault of the forwarding company.
Please check the delivered Solar Inverter
carefully!
Should you notice any damage to the
packaging or to the Solar Inverter, please
notify the forwarding company immedi-
ately. If required, your specialist dealer will

Integrating the Solar Inverter
in the PV System
Rating of the PV Generator
The technical data of the selected PV
generator must be compatible with the
specification of the Solar Inverter (see
Technical Data). An incompatible rating
may reduce the yield or destroy the
device. The rating program Sunways NT
Sundim can help you select the correct PV
generator rating. You will find Sunways
NT Sundim on the enclosed CD ROM or
on our homepage www.sunways.de.
Prior to planning your system, please take
the following considerations into account:
· Mind the orientation of the modules.
In Central Europe, you will gain a maxi-
mum yield if the module has a horizon-
tal angle of 30° and the PV generator
field points directly towards the south.
· The warmer the module gets, the smal-
ler the output of the cells will be.
Therefore, make sure your PV generator
has sufficient back ventilation when you
install it.
· Check your PV generator for contami-
nation approximately every three years.
Contamination mostly occurs on the
lower edge of the module; it forms a
veil that is not even washed off by
heavy rain. A loss of yield can be pre-
vented by cleaning the modules with a
wet cloth or a brush.
· Make sure none of the modules or solar
cells of your system are in the shade.
That may lead to a significant loss of
yield.
· The NT 10000 has three internal energy
units that are supplied by three inde-
pendent PV generators. The NT 10000 is
based on the «MPP multitracking» prin-
ciple; i. e. each inlet has its own MPP
controller.
