2.0
Safety
Precautions
Before
installing
this
device,
read
all
safety
instructions
in
this
document.
Disconnect
the
AC
source
from
all
AC
Modules
and/or
cover
all
modules
in
the
PV
array
with
an
opaque
cloth
or
material
before
making
or
breaking
electrical
connections
Do
not
connect
or
disconnect
modules
when
current
from
the
modules
in
the
string
or
an
external
source
is
present
Use
only
the
AC
locking
connectors
in
order
to
defend
against
untrained
personnel
disconnecting
the
modules
after
they
have
been
installed.
All
installations
must
be
performed
in
compliance
with
the
applicable
local
codes.
Installation
should
be
performed
only
by
qualified
and
suitably
licensed
personnel
Remove
all
metallic
jewelry
prior
to
installing
this
product
to
reduce
the
chance
of
accidental
exposure
to
live
circuits.
Use
only
insulated
tools
to
reduce
your
risk
of
electric
shock.
Do
not
stand
on,
drop,
scratch,
or
allow
objects
to
fall
on
AC
Modules.
Broken
glass,
J
‐
boxes,
broken
connectors,
and/or
damaged
backsheets
are
electrical
hazards
as
well
as
laceration
hazards.
If
a
module
is
cracked
after
installation,
a
qualified
person
should
remove
the
module
from
the
array
and
contact
the
supplier
for
disposal
instructions.
Do
not
install
or
handle
modules
when
they
are
wet
or
during
periods
of
high
wind.
Unconnected
connectors
must
always
be
protected
from
pollution
(e.g.
dust,
humidity,
foreign
particles,
etc.),
prior
to
installation.
Do
not
leave
unconnected
(unprotected)
connectors
exposed
to
the
environment.
A
clean
installation
environment
is
essential
in
order
to
avoid
performance
degradation.
Do
not
block
drain
holes
or
allow
water
to
pool
in
or
near
AC
Module
frames
Contact
your
module
supplier
if
maintenance
is
necessary.

these
instructions!
3.0
Electrical
Characteristics
Electrical
characteristics
and
grid
interaction
data
are
shown
in
Table
3
and
AC
Module
datasheet.
It
is
the
installer’s
responsibility
to
set
the
grid
profile
and
to
check
Enphase
pre
‐
configured
country
grid
detail
and
this
can
be
done
with
internet
access
and
by
connecting
into
the
Enphase
Enlighten
system.
If
an
installation
involves
a
Maxeon
AC
module
which
does
not
appear
on
this
list,
please
consult
the
product
label
on
the
back
of
the
module
or
visit
www.sunpower.maxeon.com
for
the
product
datasheet.
As
a
reminder
for
DC
modules:
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
ampacities,
fuse
sizes,
and
size
of
controls
connected
to
PV
output.
An
additional
1.25
multiplier
may
be
required
by
certain
local
codes
for
sizing
fuses
and
conductors.
SunPower
recommends
the
use
of
open
‐
circuit
voltage
temperature
coefficients
listed
on
the
datasheets
when
determining
Maximum
System
Voltage.
3.1
Fire
Rating
The
AC
Module
maintains
the
same
Class
C
fire
rating
associated
with
DC
modules.
4.0
Electrical
Connections
Modules
must
only
be
connected
using
the
correct
Enphase
AC
cable
and
integrated
connectors.
Do
not
alter
any
connectors.
Important!
Please
read
these
instructions
in
their
entirety
before
installing,
wiring,
or
using
this
product
in
any
way.
Failure
to
comply
with
these
instructions
will
invalidate
the
Maxeon
Solar
Technologies
Limited
Warranty
for
PV
Modules
and
Enphase
Energy
Limited
Warranty
for
microinverters.
Danger!
AC
Modules
generate
internal
direct
current
(DC)
and
output
alternating
current
(AC);
and
are
a
source
of
voltage
when
under
load
and
when
exposed
to
light.
Electrical
currents
can
arc
across
gaps
and
may
cause
injury
or
death
if
improper
connection
or
disconnection
is
made;
or
if
contact
is
made
with
module
leads
that
are
frayed
or
torn.
