chose an appropriate conductor size in order to minimize the voltage drop. For further connections of the
modules only appropriate cables with a minimum conductor cross-section of 4 mm² must be used.

Protect the wires from adverse environmental effects:
o
Only use UV-resistant cable ties for the attachment of the wires to the mounting system.
o
Protect the exposed wire from possible damage, e.g. by routing it in plastic tubes. Avoid direct
exposure to sunlight.
o
IMPORTANT : the Isc and Uoc values specified on the module with reference to the STC conditions
are normally exceeded during normal operation due to possible higher irradiation than standard
1000W/m

and also thanks to the bifacil. For this reason, refers to the data sheet of modules and to
the installation system to determine the rated voltage values of conductors, fuse values and the
size of control systems connected to the PV module output

MAINTENANCE OF MODULES
MegaCell recommends to inspect the installation on a regular basis with following minimum maintenance:
o
Check the electrical and mechanical connections to verify that they are clean, secure and
undamaged;
o
Check that mounting hardware, terminal screws and grounding components are tightly secured
with no corrosion;
o
Check transition impedances of the potential equalization;
o
Check that modules are not shaded by vegetation or any unwanted obstacles;
CAUTION
o
Do not touch live parts of cables and connectors;
o
Use appropriate safety equipment (insulated tools, insulating gloves, etc.) when handling modules;
o
If any problem with the system or individual module arises, have them investigated by a competent
specialist;
o
Replacement modules must be the same type of those to be replaced;
o
Modules generate high voltage when exposed to sunlight. Please cover both the front and rear
surface of modules with an opaque non scratch material when repairing. Repairing works must be
performed by specialized and properly trained personnel only;
NOTICE
: Follow the maintenance instructions for all components used in the system, such as support
frames, charge regulators, inverters, batteries etc.
