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.
