In order to reduce the risk of potential induced degradation (PID), Phono Solar
strongly recommends to use anti-PID solar modules in wet regions (i.e. shores,
wetlands), or to use the system negative grounding where the negative polarity of
the PV modules array (i.e. negative grounding at the DC bus bar level) is connected
to the ground. Failure to comply with this recommendation may reduce the module
performance and will invalidate the limited power warranty of the module.

GROUDING
5.1
For grounding and bonding requirements, please refer to regional and national
safety and electricity standards. If grounding is required, use a recommended
connector type for the grounding wire.
5.2
For grounding, this guide refers to module frame grounding. If grounding
is required, make sure module frames (metal exposed to touch) are always
grounded.
5.3
System grounding is not mandatory for Phono Solar modules, however
negative system grounding may be required by local authorities and can therefore
be recommended.
5.4
Phono Solar recommends the Grounding Clip (Cat. No. 1954381 (Supplier: TE))
when grounding.
5.5
The grounding lug must be a tin-coated copper lug, silver in color. Do NOT use a
bare copper lug, which is brown.
Please refer to relevant connector specifications for instructions.
For grounding clip, using a cross-recessed screwdriver, thread the screw into the hole
until the head is flush with the base and the base is flush with the frame, then tighten
the screw with another ¼ to ½ turn. Insert the wire into the wire slot. Press down
on both ends of the wire (the wire slot will cause the wire to form a slight curve).
Manually, or using channel lock pliers, push the slider over the base until it covers the
base. This will terminate the wire.
Warning: Do not attempt to drill holes in the module frame or in the glass surface of
the module. Any such modifications will void the PHONO SOLAR product warranty.
3.4
When installing a module on a pole ensure that the pole and mounting rail can
withstand anticipated local winds. The pole must be installed on a hard base.
3.5
Ensure that the installation height is such that the lowest modules will not be
covered by accumulated snow or shaded by the surroundings.
3.6
Ensure that there is adequate ventilation under the modules, conforming to local,
regional and state standards and regulations.
3.7
A minimum distance of 10cm, between the roof plane and the frame of the
module is generally recommended.
3.8
Observe the linear thermal expansion of the module frames. A minimum distance
of 1cm between two modules is generally recommended.
(Note: All instructions hereafter are for reference only. A licensed/qualified
person or installer must be responsible for the design, installation, mechanical
load calculation and security of the photovoltaic system.)
4.1
Any hardware used must be compatible with the mounting material to avoid
galvanic corrosion.
4.2
Only use connectors that are designed for photovoltaic systems and that match
PHONO SOLAR modules.
4.3
When working with the connectors only use tools as recommended by the
connector manufacturer.
4.4
PHONO SOLAR recommends that the same type of modules are connected
together in order to avoid any system power loss.
4.5
The maximum number of series connected modules depends on system design,
the type of inverter used and environmental conditions.
4.6
Select insulated cables that are able to resist to ultraviolet radiation and
extreme weather conditions.
4.7
The rated voltage of the cable chosen must be appropriate to the overall
maximum voltage of the system.
4.8
The module frame may be grounded according to local, regional and state
safety and electrical standards. Ensure that a recommended connector or equivalent
is used for the grounding cable. The grounding cable must be properly fastened to
the module frame.
