4.3 Cable Management
Use cable clips or cable ties wraps to attach the AC cable to the
racking. The cable must be
supported to avoid any cable undue
sag as per local requirement.
For Performance 3 AC modules, be
careful to not unplug the DC
cable premounted in factory into
specific cable supports.
Dress any excess cabling in loops so
that it does not contact the roof. Do
not form loops smaller than 12 cm in
diameter.
4.4 Microinverters Connection
Refer to the major installation steps defined in Section4.2and listen
for a click:
1) when the microinverters are pop
out and
2) when AC connectors engage
Inspect the AC connectors to ensure
that they are not broken, misshapen,
or otherwise degraded prior to
connection.
Cover any unused connectors on the
AC cable with Enphase Sealing Caps.
Listen for a click as the sealing caps
engage.
CAUTION! Install sealing caps on all unused AC
connectors as these connectors become live
when the system is energized. Sealing caps are
required for protection against moisture ingress.
3,0 Module Mounting
This section contains information for AC Modules.
Ensure that you
use the correct information for your module type.
The Maxeon Solar Technologies Limited Warranty for PV Modules is
contingent upon modules being mounted in accordance with the
requirements described in this section.
5.1 Site Considerations
AC Module should only be mounted in locations that meet the
following requirements:
Maximum Altitude: AC Modules can be installed in locations with a
maximum of 2000 meter above sea level.
Operating Temperature: AC Modules must be mounted in
environments that ensure that the modules will operate within the
following maximum and minimum temperatures:
Max. Operating Cell Temp. +85°C
Max. Operating microinverter Temp. + 60°C
Max. AC Module Ambient Temp. +50°C
Min. AC Module Operating Temp. −40°C
Design Strength: AC Modules are designed to meet a maximum
positive (or upward, e.g. wind) and negative (or downward, e.g.
static load) design pressure when mounted in the mounting
configurations specified in Appendix for the details on load ratings
and mounting locations. AC Modules have also been evaluated to
IEC 61215 for a positive or negative design load of 3600 Pa with a
1.5 Safety Factor.
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.
Important!
Refer to Appendix that show where to mount in module
frame and the allowable load ratings corresponding to the mounting
zones chosen. To use the tables, identify the two mounting zones in
which you wish to mount. You may choose to mount at any location
as long as the mounting points are symmetric about one axis of the
module. Identify the combination of mounting zones you have
chosen in the Appendix and then refer to the corresponding load
rating. Note also that load ratings are different for modules
supported by rails; versus systems that attach modules underneath
the module frame or without rail support.
Additional Authorized Operating Environments:
Modules can be mounted in the following aggressive environment
according to the test limits mentioned below:
Salt mist corrosion testing: IEC 61701 Severity 6*
Ammonia Corrosion Resistance: IEC 62716 Concentration: 6,667 ppm
*Severity 8 for SPR-P7-XXX-BLK
Excluded Operating Environments
Certain operating environments are not recommended for
SunPower AC modules, and are excluded from the Maxeon Solar
Technologies Limited Warranty for these modules. Maxeon’s
modules should not be mounted a site where it may be subject to
direct contact with salt water, or other aggressive environment.
Maxeon’s modules should not be installed near flammable liquids,
gases, or locations with hazardous materials; or moving vehicles of
any type.
Contact Maxeon Solar Technologies if there are any unanswered
questions concerning the operating environment.
5.2 Mounting Configurations
Modules may be mounted at, appropriate orientation to maximize
sunlight exposure.
In order to prevent water from entering the junction box (which
could present a safety hazard), modules should be oriented such
that the junction box is in the uppermost position and should
not
be
mounted such that the top surface faces downward.
In addition, ensure the module orientation also prevents the
microinverter from direct exposure to rain, UV and other harmful
weather events (ice/snow).
We also want to remind that the watertightness is not ensured by
the modules but by the mounting system and that drainage should
be well designed for AC modules. Maxeon recommends for a good
performance of the system (reduction of soiling effect/water
pooling) a minimum of 5° tilt angle.
Clearance between the module frames and structure or ground is
required to prevent wiring damage and allows air to circulate
behind the module. The recommended assembling clearance
between each module installed on any mounting system is a
minimum of 5 mm distance.
Clearance between the module frame and roof surface is required
to prevent wiring damage and to enable air to circulate behind the
module. Therefore a minimum of 50mm is required between the
module frame and the roof surface.
When installed on a roof, the module shall be mounted according to
the local and regional building and fire safety regulations. In case
the module is installed in a roof integrated PV‐System (BIPV), it shall
