The modules may not be operated with a higher voltage than the admissible system
voltage.
The maximum number of modules which can be connected in series can be worked out
from the maximum input voltage/input current range of the inverters/charge regulators
used, the type of module used and local temperature conditions. Under no
circumstances may the system voltage of 1000 V be exceeded.
The maximum reverse current carrying capacity is 16 A. If more than two strings are
connected in parallel, this may be exceeded in the event of a fault, which is why line
fuses with a maximum of 16 A should be used.
Please observe the applicable wind force, wind speed and snow load factors for the
respective region. Static calculations may need to be performed in certain cases.
Always ensure that the modules have sufficient secondary ventilation.
To ensure that the photovoltaic system achieves an optimum yield, please also
establish the most suitable orientation and angle of inclination of the photovoltaic
modules.
Shading leads to reduced yields, so make sure that the photovoltaic modules are free
from shadows all year round.
Shading leads to:
oreduction of yield
ooverload and overheating of the free-wheeling diode and of the module as well
as other components
odestruction of the free-wheeling diodes, which are not made for permanent strain,
in extreme cases
Shading can lead to loss of yield, hot spots on the cells, discoloration of the conductor
track, building of bubbles in the foil and fire –ertex solar does not assume liability for these
cases.
Please pay attention to not shading the modules all year around.
Ertex modules should not be installed in areas in which there is a possibility of any kind
of corrosive atmosphere.
The photovoltaic module is not classed as explosion-protected equipment. Accordingly,
it may not be installed in the vicinity of highly flammable gases and vapours.
6 Mounting Ertex modules
The background and support surfaces must be sufficiently stable in terms of their
dimensions.
Forces acting on the structure must not be transferred to the module.
The supports must be designed such that the glazing can be inserted without twisting.
In accordance with correct block setting procedures, the frame anchor mechanisms for
fixed glazing must be positioned on the lower part of the frame in such a way that a
fixing mechanism is located 150 mm to 200 mm from each corner of the frame and this
fixing mechanism is able to take the weight of the glazing on its own.
Glazing rebates and glazing bars must be pre-treated in accordance with the regulations
in ÖNORM B 3722.
The dimensions of the glazing rebates (width and height) must be stipulated on site in
accordance with ÖNORM B 3722.
