1.0 Introduction:
These instructions are designed to ensure safe installation of Phaesun
solar modules. Please read the operating instructions for this product
carefully and completely before installation.
IMPORTANT!
Failure to comply with these instructions will invalidate the Phaesun
Limited Warranty for PV Modules. Read this instruction sheet in its
entirety before installing, wiring, or using this product in any way.
1.1. Disclaimer of Liability
The installation techniques, handling and use of this product are
beyond company control. Therefore, Phaesun does not assume res-
ponsibility for loss, damage or expense resulting from improper instal-
lation, handling or use.
1.2 Limited Warranty
Module limited warranties are described in the Phaesun warranty cer-
tificates obtainable at www.phaesun.com
1.3 Application Conditions
This solar module shall not be used for applications that connect to
the utility electricity grid and Phaesun has no liability, and all warran-
ties shall be voided, to the extent the modules are used in any such
application.
2.0 Safety Precautions:
DANGER!
Module interconnects pass direct current (DC) and are sources of vol-
tage when the module is under load and when it is exposed to light.
Direct current can arc across gaps and may cause injury or death if
improper connection or disconnection is made, or if contact is made
with module components that are damaged. Do not connect or dis-
connect modules when current from the modules or an external sour-
ce is present.
• Cover all modules in the PV array with an opaque cloth ormaterial
before making or breaking electrical connections.
• It is imperative to use the supplied locking connectors and safety
clips in order to defend against untrained personnel disconnecting
the modules once they have been installed.
• All installations must be performed in compliance with all applicable
regional and local codes.
• There are no user serviceable parts within the module. Do not
attempt to repair any part of the module.
• Installation should be performed only by qualified personnel. Re-
move all metallic jewelry prior to installing this product to reduce the
chance of accidental exposure to live circuits
• Use insulated tools to reduce your risk of electric shock
• Do not stand on, drop, scratch or allow objects to fall on modules
• If the front glass is broken, or the back sheet is torn, contact with
any module surface or module frame can cause electric shock
• Do not install or handle the modules when they are wet or during
periods of high wind
• Contact your module supplier if maintenance is necessary
• Save these instructions
3.0 Electrical Characteristics:
The module electrical ratings are measured under Standard Test Con-
ditions (STC) of 1 kW/m² irradiance with AM 1.5 spectrum and a cell
temperature of 25º C. Phaesun modules have specific electrical charac-
teristics as shown on the datasheets.
A photovoltaic module may produce more current and/or voltage than
reported at STC. Sunny, cool weather and reflection from snow or
water can increase current and power output. Therefore, the values of
Isc and Voc marked on the module should be multiplied by a factor of
1.25 when determining component voltage ratings, conductor ampa-
cities, fuse sizes, and size of controls connected to PV output. An addi-
tional 1.25 multiplier may be required by certain codes for sizing fuses
and conductors. Phaesun recommends the use of open-circuit voltage
temperature coefficients listed on the datasheets when determining
Maximum System Voltage.
4.0 Electrical Connections:
Modules may be connected in series and/or parallel to achieve the
desired electrical output as long as certain conditions are met. Please
use only the same type of modules in a combined source circuit.
4.1 General Wiring
Phaesun recommends that all wiring be double insulated with a mi-
nimum rating of 85º C (185° F). All wiring should use flexible copper
(Cu) conductors. The minimum size should be determined by the appli-
cable codes. We recommend a size not less than 4mm2. The insulation
type should be appropriate for the type of installation method used
and must meet SCII (Safety Class II) and IEC 61730 requirements.
4.2 Equipment Grounding
Please refer to the applicable regional and local codes on grounding
PV arrays and mounting frames for specific requirements (e.g. light-
ning protection).
4.3 Series Connection
The modules may be wired in series to produce the desired voltage
output. Extra care must be taken in case of system voltage above 50V
DC. Do not exceed the maximum system voltage.
4.4 Parallel Connection
The modules may be combined in parallel to produce the desired cur-
rent output. Series string must be fused prior to combining with other
strings if the resulting maximum reverse current exceeds the fuse ra-
ting as shown in the datasheets. Bypass diodes are factory installed in
the modules. Please refer to the applicable regional and local codes
for additional fusing requirements and limitations on the maximum
number of modules in parallel
5.0 Module Mounting:
The Phaesun Limited Warranty for PV Modules is contingent upon mo-
dules being mounted in accordance with the requirements described
in this section.
5.1 Site Considerations
Phaesun modules should be mounted in locations that meet the follo-
wing requirements:
Maximum Operating Temperature +90°C, + 194°F
Minimum Operating Temperature -40°C, -40°F
IMPORTANT!
Care should be taken to provide adequate ventilation behind the mo-
dules, especially in hot environments. When mounting modules in
snow prone or high wind environments, special care should be taken
to mount the modules in a manner that provides sufficient design
strength while meeting local code requirements. Excluded Operating
Environments: No Phaesun module should be mounted at a site where
it may be subject to direct contact with salt water.
5.2 Installation
Modules may be mounted at any angle from horizontal to vertical.
Select the appropriate orientation to maximize sunlight exposure.
