SAFETY

General safety instructions

The design and installation of photovoltaic solar systems requires special skills and knowledge. Proper

implementation is the responsibility of the system designer and installer.

TRIMAX Solar PV modules may only be installed in compliance with all locally and nationally applicable

standards, rules and regulations. Check and follow all safety instructions, including those given by other

component suppliers.

Please contact our Technical Service if you have any questions about the instructions.

Fire protection

TRIMAX Solar PV modules have been tested in accordance with the provisions of the IEC EN 61730 directive

with application class A.

The fire safety has been evaluated with class C.

Please note the building code requirements. In Germany, it is the Landesbauordnung in your state. The roof

must be covered with a suitable fire-resistant material.

The installation of PV systems on a roof can affect the fire safety of a building. Compared to other technical

installations, they do not pose a particularly increased fire risk.

However, improper installations can lead to a hazard and fire. In particular, defects in current-conducting

components of the PV system can lead to the formation of electric arcs.

For this, please refer to VDE-AR-E 2100-712. This VDE application rule applies to the planning and installation

of low-voltage systems for photovoltaic (PV) power supply systems on or on buildings together with the

requirements of DIN VDE 0100-712.

7 ANLEITUNG 04_21

This VDE application rule contains supplementary recommendations to mitigate the likelihood of electric

shock to emergency personnel in case of fire (or similar) resulting from the fact that PV modules can produce

voltage when exposed to light, even if the AC side is disconnected.

•In order to inform firefighters that there is a PV system on the roof of the house, for example, it is

recommended that a photovoltaic system fire sign be placed on the side of the building where the

main access road is located. By having a PV system sign immediately visible, firefighters will have

advance notice of potential hazards that may be posed by the PV system in the event of a fire.

•Create sufficiently detailed documentation of the PV system ,to support a hazard-free execution of the

extinguishing process. Ensure that the system documentation is accessible to the fire department in

the event of a fire.

Safety distances for an extinguishing process in PV systems (according to DIN VDE 0132)

Low voltage High voltage

Spray jet: 1 meter 5 meters

Full jet: 5 meters 10 meters

•Do not install modules near open fire or flammable and explosive gases/substances.

•Only use plugs and sockets of the same manufacturer and type.

•Only use devices, plugs, cables and support frames that are suitable for use in a solar power system.

•Use temperature and UV resistant materials.

Mechanical installation

General notes

Always use constructions and materials that have been specially developed and certified for the installation of

photovoltaic modules. Always follow the instructions and safety precautions of the mounting system

manufacturer.

•Do not remove any components, such as plugs or cables, or attached nameplates.

•Do not apply paint or glue to the top of the module.

•Do not concentrate artificial sunlight on the solar module.

•Do not disassemble, drill or modify the frame or other parts of the PV module.

Safety instructions

•Do not install in high winds and prevent objects from falling from the roof.

•Secure the work area so that no one on or under the roof can be injured.

•When installing a module on a roof or building, make sure it is securely fastened.

•Avoid subjecting the frame to lateral tension and compression forces, as this could damage the glass.

•Do not bend the module frame.

•Do not damage the frame.

•Do not place the module down hard.

•Do not drop any objects on the module.

•Do not place heavy objects on the module.

8 ANLEITUNG 04_21

•Do not step on the module.

•Make sure that the drainage holes of the PV module are not blocked.

•Roof penetrations must be properly sealed.

•Ensure that cables or plugs are not trapped between the module and the substructure.

Electrical installation

General notes

The electrical connection must be carried out by a competent, authorized person/company. The electrical

installation of the PV system must be carried out in accordance with the respective national electrical

regulations or the applicable national regulations.

Safety instructions

•Exercise extreme caution during all work on the wiring.

•Observe the safety instructions for all other components used in the PV system.

•Do not wear metal rings, watch bands, ear, nose or lip rings, or other metal objects during installation

or troubleshooting of photovoltaic systems.

•Do not install solar modules or wiring with wet male and/or female connectors.

•A single module can generate DC voltages in excess of 30 V when exposed to light of any intensity.

Contact with a DC voltage of 30 V or more is potentially hazardous. Connecting modules in series or

parallel increases the voltage or electrical current.

•During installation, completely cover the module with a dark, opaque material to prevent current

generation.

•Do not install/operate damaged modules, as contact with the surface of the module or frame may

cause electric shock.

•Do not attempt to repair a module with broken glass or defective back panel.

•Do not disconnect modules under load to avoid electrical arcing. Contact with electrically active parts

of the modules, can cause burns, sparks and fatal shock, whether the module is connected or not.

•Do not use the junction box or cables as a handle.

•Do not use lubricant on the connectors.

•Do not remove the rubber rings on the junction box or connectors.

•Do not immerse modules or connectors in liquid.

•Do not insert electrically conductive objects into the plugs and/or sockets.

•Do not short-circuit the solar module cables under any circumstances.

•Ensure correct polarity of the cables.

•Only use or connect plugs and sockets of the same manufacturer and type.

•When connecting the plugs, make sure that they are securely connected.

•Lay cables carefully and protect them from the weather.

•Avoid cable damage due to sharp edges.

•Avoid cable damage caused by cable ties that are too tight.

•Do not fall below the smallest bending radius of the cables.

•Avoid tensile loads, especially on junction boxes and plug connections.

The cross-sectional area of the cable is 4mm2 or 12AWG. The smallest bending radius of the cables must not

be less than 43mm. Cable damage caused by excessive bending or by the cable management system is not

covered by the warranty.

PLANNING AND INSTALLATION

Intended use

•TRIMAX PV modules are suitable for outdoor operation.

•Ambient temperature range: -40°C to +40°C

•Operating temperature range: -40°C to +85°.

•Humidity: 100% and rain

•Mechanical load capacity: snow load: 5400Pa wind load: 2400Pa

•< 2000m altitude sea level

•Do not expose the module to external light sources.

•There is a risk of corrosion if the module is exposed to salt (e.g. near the sea) or sulfur sources. The

modules have passed the salt spray test according to IEC61701, but galvanic corrosion may occur

between the aluminum frame of the modules and the mounting or grounding elements if these

elements are made of different metals. The modules can be installed in coastal locations <500m, but

the components should be protected from corrosion.

•The module should not be exposed to unusual chemical stresses.

•Ensure that the modules are not subjected to wind or snow loads that exceed the maximum allowable

loads.

•In regions with heavy snowfall, select the height of the mounting structure so that the lowest edge of

the module is not covered by snow and cannot beshaded by plants or trees or soiled by soil.

•Lightning protection is recommended for PV systems that are to be installed in locations with a high

probability of lightning strikes.

Shading

The modules should not be shaded at any time. Shading leads to a

lower power output. Furthermore, systemic shading can lead to

accelerated aging and damage to the module and failure of the

system. Perform a shading analysis. Shading objects such as trees

or houses can have a significant impact on the yield prediction.

Ensure sufficient row spacing for ground-mountedsystems to

avoid self-shadowing. Observe and avoid close shading by

chimneys, dormers, antenna tubes, lightning protection equipment

or overhead cables.

Consider the internal bypass diode configuration of the PV module

when selecting the orientation to ensure optimal electrical

performance against possible shading of the module.

In case of shading or soiling, in addition to the Schotky diodes, the

parallel connection of the half cells has the advantage that current

continues to flow through the unaffected string and thus 50% of

the original power still remains, but systemic shading should be

avoided to prevent permanent stress on the bypass diodes.

•Please do not attempt to open the junction box to replace

the diode.

Tilt Angle

PV modules should be installed in a location where they can receive the maximum amount of sunlight

throughout the year. In the Northern Hemisphere, the modules should face south, and in the Southern

Hemisphere, they should face north. As a rule of thumb, the tilt angle should be approximately equal to the

latitude of the project site and point toward the equator.

PV modules connected in series should be installed in the same orientation and with the same tilt angle. The

greatest power is generated when direct sunlight falls on the PV modules.

Dust and dirt accumulating on the surface of the modules can affect performance. TRIMAX Solar

recommends that modules be installed with a tilt angle of at least 15 degrees so that dust or dirt can be

washed off more easily by rain.

Glare behavior / Glare assessment

Under certain circumstances (e.g. nature reserves, traffic routes, airports), it may be necessary to check the

glare behavior of the PV power plant. Factors for the strength of the reflection include the position of the sun,

module orientation, coordinates of the installation site and the surface properties of the solar module.

Contact a professional provider for a glare assessment. TRIMAX Solar high performance PV modules are

coated with an ARC (Anti Reflective Coating). The glass coating with nano technology ensures that less light

is reflected and more light reaches the solar cells.

Bifacial Modules

TRIMAX Solar high power PV modules are equipped with bifacial PERC cells.PERC stands for Passivated

Emitter Rear Cell. The structure of the PERC cell essentially allows for improved light output at the rear of

the cell, which in turn increases electron yield. The bifaciality (the ratio of front and rear output under the

same conditions) can reach 65% ± 5%. The bifacial extra yield depends mainly on the system design, especially

the row and ground spacing, the angle and the reflectivity of the ground (albedo). Additional yields between 5

and 15% are possible. The reflectance varies depending on the soil resulting in different power generation. The

irradiance reflected to the back of the bifacial glass/film solar modules must not exceed 300 W/m2.

Electrical design

Maximum system voltage (Umax): 1000V or 1500V depending on product type.

Please check the nameplate and data sheet accordingly. For further technical data, please refer to the

respective data sheets - available online at www.trimax-solar.com.

•To avoid power loss or damage to the PV system, use only modules of the same type and

power within the same circuit.

•Protect the solar modules from overvoltage, e.g. voltage peaks from battery charging,

generators, etc.

•Only use plugs of the same manufacturer and type for cable extensions.
