performed by qualified and authorized installer.
All installation instructions should be read and

•

understood before performing any installation.
Do not touch the solar module with bare hands.

•

It may result in a burn or injury.
Do not disassemble the solar module.

•

After installation or repair, check that the solar module

•

are operating properly.
In the event that the currently used solar module or

•

parts have been replaced the newly replaced module
and parts must have the same model name and parts
as the previously installed solar module.

Do not let anyone approach the solar module who has

•

little knowledge of solar modules or on the measures to
take when solar modules are damaged in order to avoid
the risk of injury or electrical shock.

Secure all necessary permits and licenses to install

•

the solar modules.
Do not locate the solar module horizontally, as this may

•

cause dirt or white efflorescence(glass deformation).
Panels are not intended for use indoors or on moving

•

vehicles of any kind.
Industry standard rated specifications are made at

•

conditions of 1000W/m irradiance and 25°C (77°F)
solar cell temperature. Colder temperatures may
substantially increase voltage and power.

Keep the solar module and system away from children

installation.
Be careful not to damage the cable when using a tool

•

such as a knife to remove the cable tie that fixes the
junction box cable.

2

Partial shadowing may substantially reduce panel and

•

system output and may be the reason for the damage
of solar module.

Care must be taken to avoid low tilt angles which may

•

cause dirt to buildup on the glass against the frame
edge.

Dirt build-up on the surface of the panel may

•

cause active solar cells to be shaded and electrical
performance to be impaired.

After Installation

Plug in the connector tightly and ensure that the wiring

•

properly works.
Conduct periodic inspection of the panels for damage

•

to front glass, back sheet, frame, junction box, or
external electrical connections.

Check electrical connections for loose connections

•

and corrosion.
PV panels can operate effectively without ever being washed,

•

although removal of dirt from the front glass can increase
output.

Water, ethanol or a conventional glass cleanser with

•

a micro-fiber cloth can be used for regular washing or
rinsing of the front glass to remove dust, dirt or other
deposits.

•

Do not use ground water containing calcium carbonate
components when cleaning glass.

Caution

Avoid all electrical hazards when installing, wiring,

•

operating and maintaining all panels.
Do not connect panels that have different electrical

•

properties or physical configurations in the same
system.

Match the polarities of cables and terminals when

•

making the connections; failure to do so may result in
damage to the panel.

When reverse currents can exceed the value marked

•

on the name plate, a properly rated and certified
over-current device(fuse or circuit breaker) must be
connected in series with each panel or string of panels.

The rating of the over-current device shall not exceed

•

the maximum series fuse rating marked on the name
plate.

The panel contains factory installed bypass diodes

•

located inside the junction box.
When installing the system, it is recommended to

•

install a lightning rod to protect the system.
The induced overvoltage by lightning can cause the

•

system damage, you should design conductor loop
connection as minimum as possible.

The junction box should not be opened. Opening the

•

junction box will void the warranty.
Panels with a suspected electrical problem should be

•

returned to LG Electronics for inspection and possible
repair or replacement as per the warranty conditions
provided by LG Electronics.

When the module installing in series or in parallel (e.g.

•

using for extension cables, etc.), the connector of each
module should be the same products. (mated with its
original female or male connector of the same supplier)

Diodes

All LG modules are equipped with factory installed

•

bypass diodes. The factory-installed diodes provide
proper circuit protection for the module from
unexpected shadows.

Series Connection

The solar modules may be wired in series to produce

•

the desired voltage output.
The current of each module connected in series

•

should be the same.
The maximum number of series connected modules

•

can be determined by basis on maximum system
voltage, the 125% safety factor, and the module Voc
which can be checked in “Product Specifications” in
this document.

The maximum solar module configuration can be

•

found in “Product Specifications”.

Electrical Connections

Shock hazard may occur near the solar modules

•

electrical connections.
Modules may be connected in series and/or parallel

•

to achieve the desired electrical output as long as it
is within the guidelines on the product specification
sheet.

Please use only the same type of modules in a

•

combined source circuit.
Do not disconnect the module under when it is

•

operating. Shock hazard may occur near the solar
modules connection means.

06

………….

Series connection for more voltage

Parallel Connection

General Wiring

The solar modules may be combined in parallel to

•

produce the desired current output.
When modules are combined in parallel, the total

•

current is equal to the sum of currents from each
module.

The voltage of each module connected in parallel

•

should be the same.
When connecting plural strings of modules in parallel

•

every series string or solar module must be fused prior
to combining with other strings.

Abide with all applicable federal, state, and local codes

•

for additional fusing requirements and limitations on
the maximum number of solar modules in parallel.

Maximum series fuse rating is refer to “Product

•

Specifications; page 11”.
Parallel configuration is not limited if proper measures

•

are taken to block the reverse current flow, e.g. fuses
for the protection of the module and cables from over­current for prevention of unbalanced string voltage.

A multiplying factor is required for increased output

•

of the PV modules. Under normal conditions, a PV
module is likely to experience conditions that produce
more current and/or voltage than reported at standard
test conditions. The requirements of the National
Electrical Code (NEC) in Article 690 shall be followed
to address these increased outputs. In installations
not under the requirements of the NEC, the values
of Isc and Voc marked on this PV module should
be multiplied by a factor of 125% when determining
component voltage ratings, conductor ampacities,
fuse sizes, and size of controls to the PV output.

Depending on national directives, additional safety

•

factors might be applicable for over current protection.

LG Electronics recommends that all wiring be double

•

insulated with a minimum rating of 90°C (194°F).
All wiring should use a flexible copper (Cu) conductor.

•

The minimum size should be determined by the

•

applicable codes.
LG Electronics recommends a size no smaller than

•

2

4mm .

Earth Grounding

All work must be conducted in conformance with all

•

Federal, State, and local codes and standards.
