Electrical
Connections
and
System
Monitoring
Modules
may
be
connected
in
series
and/or
parallel
to
achieve
the
desired
electrical
output
as
long
as
optimum
design
parameters
are
achieved
certain
conditions
are
met.
Please
use
only
the
same
type
of
modules
in
a
combined
source
circuit.
Do
not
mix
the
modules
with
different
nameplates
without
authorization
by
Maxeon.
Even
if
allowed
by
local
regulation,
Plug
and
Socket
connectors
mated
together
in
a
PV
system
must
be
of
the
same
type
(model,
rating)
from
the
same
manufacturer
i.e.
a
plug
connector
from
one
manufacturer
and
a
socket
connector
from
another
manufacturer,
or
vice
versa,
shall
not
be
used
to
make
a
connection.
Maxeon
recommends
a
conservative
minimum
bending
radius
(R)
5x
cable
diameter
must
be
maintained
and
must
not
be
bent
on
the
direct
exit
of
the
connector
or
junction
box.
Avoid
exposure
of
electrical
connections
to
direct
sunlight
and
do
not
place
the
connector
in
a
location
where
water
could
easily
accumulate.
Installers
must
refer
to
connector
manufacturer’s
instruction
for
further
installation
and
connection
requirements.
Connectors
are
factory
assembled
with
intentional
gaps
between
the
cable
nut
and
the
body
of
the
connector.
Do
not
retighten
module
connector
nuts
as
this
may
lead
to
stress
cracking
of
the
connector
assembly
and
will
void
the
warranty.
4.1
Equipment
Grounding
To
reduce
the
possibility
of
electrical
shock,
ground
the
frame
of
the
module
or
array
per
NEC
before
wiring
the
circuit.
In
order
to
install
in
accordance
with
their
CSA
Listing,
Maxeon
modules
must
be
grounded
using
grounding
hardware
that
meets
requirements
for
grounding
systems
in
UL
61730
and
UL
61215
on
anodized
aluminum
frames.
Maxeon
recommends
to
refer
to
the
applicable
regional
and
local
codes
and
requirements
on
grounding
PV
arrays
and
mounting
frames
in
conjunction
with
your
racking
supplier.
In
addition,
to
avoid
corrosion
due
to
the
use
of
dissimilar
metals
Maxeon
recommends
stainless
steel
between
copper
and
aluminum.
4.2
System
Grounding
Review
Table
2
below
for
the
proper
grounding
techniques
for
the
installation
of
your
particular
Maxeon
modules.
4.3
Series
Connection
The
modules
may
be
wired
in
series
to
produce
the
desired
voltage
output.
Do
not
exceed
the
maximum
system
voltage
shown
in
module
datasheets
and
product
label.

For
models
not
shown
here,
please
contact
Maxeon
technical
support
or
visit
www.sunpower.maxeon.com
.
Electrical
parameters
are
measured
at
Standard
Test
Conditions
(STC).
The
series
fuse
must
have
an
interrupting
rating
that
is
equal
to
or
greater
than
the
maximum
fault
current
that
the
fuse
is
required
to
interrupt,
including
contributions
from
all
connected
sources
of
energy.
Refer
to
NEC
Article
100,
Part
II
as
to
what
type
of
series
fuse
is
acceptable
for
modules
rated
at
higher
than
600
V
dc
system
voltage.
4.4
Parallel
Connection
The
modules
may
be
combined
in
parallel
to
produce
the
desired
current
output.
Each
series
string
or
module
may
be
required
to
be
fused
prior
to
combining
with
other
strings
if
the
resulting
maximum
fuse
size
allowed
(number
of
modules
which
can
be
connected
in
parallel
and
protected
by
one
fuse)
exceeds
the
fuse
rating
as
shown
in
the
module
datasheet
and
product
label.
Please
refer
to
the
NEC
Article
690
for
additional
fusing
requirements.

Failure

with
this
requirement
will
reduce
system
performance
and
invalidate
Maxeon’s
Limited
Power
Warranty
for
PV
Modules.
5.0
Module
Mounting
The
Maxeon
Limited
Warranty
for
PV
Modules
is
contingent
upon
modules
being
mounted
in
accordance
with
the
requirements
described
in
this
section.
5.1
Site
Considerations
Maxeon
modules
should
only
be
mounted
in
locations
that
meet
the
following
requirements:
Operating
Temperature:
All
Maxeon
modules
must
only
be
mounted
in
environments
that
ensure
they
will
operate
within
the
following
temperatures:
Operating
Temperature
range
(ambient)
‐
40°C
to
+85
°C
‐
40°F
to
+185
°F
Adequate
ventilation
should
be
provided
behind
or
underneath
the
modules,
especially
in
hot
environments.
Shading:
Modules
should
be
installed
so
that
permanent
shading
of
cells
is
avoided
and
partial
shading
that
may
occur
during
certain
times
of
the
day
or
year
is
minimized.
Permanent
shading
is
defined
as
shade
that
is
cast
over
the
same
position
(of
constant
area)
of
the
solar
module
throughout
the
generation
hours
of
the
day.
Shading
may
induce
in
certain
cases
strong
energy
production
reduction,
even
in
case
of
small
shading
and
should
be
avoid
as
much
as
possible,
especially
at
mid
‐
day
when
the
production
is
maximum.
Design
Strength:
Maxeon
modules
are
designed
to
meet
a
positive
(downward)
and/or
negative
(upward)
withstanding
test
pressure
when
mounted
as
per
the
guidelines
in
Section
5.2
and
configurations
in
Appendix.
Test
loads
are
for
information
purposes
only;
design
loads
should
be
considered
for
the
project
design.
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
Certain
operating
environments
are
not
recommended
for
Maxeon
modules,
and
are
excluded
from
the
Maxeon
Limited
Warranty.
Modules
are
designed
for
a
maximum
altitude
of
2000
m.
No
Maxeon
module
should
be
mounted
at
a
site
where
it
may
be
subject
to
direct
contact
with
salt
water,
or
other
aggressive
environment.
Modules
should
not
be
installed
near
flammable
liquids,
gases,
or
locations
with
hazardous
materials;
or
moving
vehicles
of
any
type.
Performance
Series
Mounting
Orientation
Commercial
Performance
Series
(P
‐
Series)
modules
are
designed
to
perform
better
if
installed
in
landscape
orientation.
In
landscape
orientation,
P
‐
series
modules
maintain
higher
power
in
conditions
of
row
‐
to
‐
row
shading
and/or
edge
soiling.
