1.0 General information

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.
