Installation of Solar Modules
Solar Modules must be installed in accordance with all applicable codes. Some of them are
the local building codes, the Building Code of Australia, AS / NZS 4777 and AS / 5033. The
must be installed by a licenced, competent person.
Solar Array Maximum Voltage.
The maximum Voltage Open Circuit (VOC) must be calculated to account for low
temperature voltage rise. Failure to do may damage the equipment and void warranty.
For guidance see AS / NZS 5033 4.2 PV array maximum voltage.
The maximum Voltage Open Circuit for this equipment is 380 Vdc.
For example, if the lowest recorded temperature is 4 to 0 degrees C and the VOC of a
module is 44.2 Vdc, one would multiply 44.2 by 1.1 equalling 4.42 volts.
Adding 44.2 and 4.42 equals the low temperature VOC of 48.62.
Dividing the maximum VOC input of 380 Vdc by 48.62 yields the maximum number of solar
modules 7.81. Rounding down yields 7 modules max at that low temperature.

Solar Array maximum current.
Paralleling of the solar array is not recommended as the maximum rated Array Short circuit
current is 12 amps.
Galvanic considerations outdoor unit.
The outdoor unit is to be treated as a non-galvanically isolated regulator. The solar isolation
switches must be rated for the full array voltage and current. If connected to the AC supply,
the outdoor unit must be connected to the 230-volt AC distribution board via a type A or B
residual current and overcurrent device.
Solar Module installation
This manual contains information regarding the installation and safe handling of solar
photovoltaic module(s). All instructions should be read and understood before attempting to
install. If there are any questions, please contact our sales department for further
explanation. The installer should conform to all safety precautions listed in this guide when
installing the modules. Local codes and regulations must be followed.
This manual does not describe specific structures and installation procedures.
An approved solar technician must be consulted to determine the following:
. The specifications of the solar photovoltaic system
. Cable material
. Connecting components
. Bracket and support
. Supporting parts
. Switching and circuit protection

Solar modules are large and require careful handling. Only a qualified technician
should install Solar Modules. Solar arrays are current limited sources. Use
appropriate protection measures when working on them. They contain hazardous
DC voltages.
Installation of Solar Modules should be performed only by qualified persons, who are familiar
with the mechanical and electrical requirements.
All electrical connections should be made with approved MC-4 type connectors, and from
the same manufacturer. (AS / NZS 5033 clause 4.3.7 (k)
One individual solar module generates DC voltage greater than 30V when exposed to
sunlight. Contact with a DC voltage of 30V or more is potentially hazardous. Do not touch
the contacts of electrical terminals.
Do not touch the module contacts.
Keep children away from the system while transport and installing mechanical and
electrical components.

Completely cover the module with an opaque material during installation to keep electricity
from being generated. Do not touch the ends of live wires. Do not wear metallic rings,
watchbands, ear, nose lip rings or other metallic devices while installing or troubleshooting
photovoltaic systems
Use only insulated tools that are approved for electrical installations.
Do not work on solar modules in wet conditions

The module frame must be properly earthed. Removal on any one module must not interrupt
the earthing of the remaining modules.
Solar Array Mechanical installation
Selecting an installation place:

. Select a suitable place for installation of the solar modules. The modules should not
be shaded during the solar window part of the day.
. The module should be facing north in the southern latitudes for best power
generation.
. An approved solar technician should be consulted to determine the best orientation
of the solar panels.
Selecting the proper support frame:
. Always observe the instructions and safety precautions included with the support
frame to be used with the modules.
. Never attempt to drill holes in the glass surface of the module. It will void the
warranty.
. Do not drill additional mounting holes in the frame of the module. It will void the
warranty.

. Modules must be securely attached to the mounting structure using four mounting
points for normal installation. If additional wind or snow loads are considered for the
installation additional mounting points should also be used.
. The support frame must be made of durable, corrosion resistant and UV resistant
material.
. The heat expansion and cold contraction of the support frame should have no effect
on its usage and performance.
Ground mounting:
. Select the height of the mounting system to prevent the lowest edge of the module
from being covered by snow in winter in areas the experience heavy snowfalls. In
addition, assure the lowest portion of the module is placed high enough that it is not
shaded by plants or trees and is free from the effects of sand and stone driven by
wind.
Roof Mounting:
When installing the modules on a roof ensure that they are securely fastened and cannot fall
because of wind or snow loads.
When installing on a roof, ensure that the roof construction is suitable. In addition, any roof
penetration required to mount the module must be properly sealed to prevent leaks.
The roof installation of solar modules may affect the fireproofing of the house construction
and it may be necessary to use an earth ground fault circuit breaker.

Provide adequate ventilation under a module for cooling. 50 mm minimum between the
module and the mounting surface.
Pole mounting:
When installing the modules on a pole, choose a pole and module mounting structure that
will withstand anticipated winds for the area. The pole must have a solid foundation.
Solar Array Wiring
The array is formed of modules in series. The switch disconnectors must be approved for
disconnecting solar DC under load.
The MC 4 connectors must be approved and from the same manufacturer at each join.
Mismatching connectors can cause failure and possible fire.

General installation:
. Do not use modules of different configurations in the same system.
. The solar photovoltaic array consists of a maximum of 10 modules of 270 watts or 8
modules of 370 watts.
. The solar array total system voltage must not exceed 380 volts DC open circuit. If
installed in an area that experiences temperatures lower than 20 degrees C the
Voltage open circuit will rise and a calculation must be done by a qualified technician.
. Both sides of an MC 4 type connection must be of the same type and manufacturer.
. Multistrand solar wire, having a minimum cross section of 2.5 sq mm or larger must
be used.
. Cable installation must comply with all local and national codes and regulations.
. A switch disconnector rated for DC must be used between the array and the outdoor
unit. If not adjacent to the array a separate switch must be installed at the array.

Earth Fault Protection Solar DC
Roof mounted DC PV arrays located on dwellings must be provided with DC earth fault
protection per US Electrical code NEC 2005 Article 690.5. Earth fault protection isolates the
Neutral conductor. (in DC this is usually the negative wire) from earth when a ground fault
occurs.
