1.0 General information

General safety information

All safety hints contained in this section

and throughout the User Manual must

be complied with at all times to guarantee

the user's safety. The described product

must not be operated if any mechanical

or electrical components are defective.

Before commissioning the system, we

strongly advise you to carefully read and

heed the instructions! Non-compliance

can have serious consequences, for exam-

ple damage to the unit or other property

or physical injuries with possible loss of

life.

The solar inverter must be installed by a

trained, qualified electrician. The electrici-

an must be approved by the competent

electricity board (EB).

The relevant tasks to be carried out are

identified by an additional adjacent

symbol in the respective chapter headings.

1.1 Safety information

The User Manual contains safety hints.

These are identified by a triangle with an

exclamation mark.



Opening the unit

Before opening the cabinet, the unit must

always be disconnected from the grid and

from the PV generator.

The unit continues to conduct a hazardous

voltage internally and at the connection

sockets for ca. five minutes after disconnec-

ting from the PV generator. The energy

storage capacitors are only fully discharged

after this period.

After disconnecting the unit from the grid

and from the PV generator, you must wait

at least five minutes before opening the

unit.

Inspecting the delivery

The condition of our products is checked

prior to delivery. Although our products

are carefully packed in recyclable packing,

transportation damages can still occur.

These are generally the transport compa-

ny's responsibility.

Please inspect the delivered solar inverter

thoroughly!

If you discover any damage to the packing

or the solar inverter, please inform the

transport company immediately. Your

specialist dealer will be glad to assist you

if required. Any damages must always be

reported to the transport company in wri-

ting seven days after receipt of the goods

at the latest.

Integration of the solar inverter into the

PV system

Design of the PV generator

The technical data of the selected PV

generator must be within the specifica-

tion of the solar inverter (see Technical

Data). The Sunways NT Sundim design

program for the PV generator may be

helpful. Sunways NT Sundim is available

on the enclosed CD or from our web-

site, www.sunways.de.

Please take account of the following

points before planning your system:

· Pay attention to the skyward alignment

of the modules. You will obtain maxi-

mum yield in Central Europe with a

module inclination of 30° to the hori-

zontal and a direct southerly alignment

of the generator field.

· The output of the cells decreases as the

module temperature increases. Install

your PV generator with adequate rear

ventilation.

· Check your PV generator for soiling ca.

every three years. This occurs particularly

at the lower edge of the modules and

forms a film, which even heavy rain can-

not wash away. Decreases in yield can be

prevented by cleaning with a wet cloth

or a brush.

· Avoid shading of individual modules or

solar cells in your system. This can result

in heavy losses in yield.
