Preparation
and
Inverter
Placement
The
inverter
is
comprised
of
a
NEMA
4
enclosure,
containing
electrical
and
electronic
components
as
well
as
AC
and
DC
integrated
disconnects.
NOTE:
If
the
inverter
is
mounted
outside,
ensure
that
the
wiring
box
remains
closed
during
the
installation
process
until
access
to
the
box
is
needed.
This
precaution
will
help
to
avoid
damage
due
to
rain,
snow,
or
condensation.
Damage
to
the
inverter
caused
during
the
installation
process
will
void
the
warranty.
The
inverter
main
housing
cover
must
remain
on
at
all
times.
NOTE:
It
is
recommended
to
store
the
inverter
indoors
before
installation.
If
the
inverter
is
to
be
stored
outdoors
before
being
installed
and
commissioned,
care
must
be
taken
to
avoid
condensation
inside
the
unit.
2.1
Criteria
for
Device
Mounting
Because
the
power
electronics
are
within
the
rainproof
enclosure,
the
inverter
can
be
mounted
outdoors.
The
maximum
life
for
the
inverter
is
achieved
by
mounting
the
unit
in
a
clean,
dry,
and
cool
location.
For
optimal
electrical
system
efficiency,
use
the
shortest
possible
AC
and
DC
cables
but
use
the
maximum
allowable
cable
size.
Install
the
inverter
in
an
accessible
location
following
local
electric
codes
for
enclosure
proximity
to
other
equipment.
Although
the
inverter
is
designed
to
function
at
full
power
continuously
up
to
45°C
ambient
temperature,
for
optimal
inverter
life
and
performance
do
not
mount
the
inverter
in
direct
sunlight,
especially
in
hot
climates.
If
the
unit
must
be
mounted
in
direct
sunlight,
a
sun
‐
shield
is
recommended
but
not
required.
It
is
recommended
that
the
inverter
is
mounted
on
the
north
side
of
buildings
or
on
the
north
side
of
a
ground
mount
PV
array.
WARNING
:
Be
sure
to
verify
load
capacity
of
wall
or
mounting
area
where
the
inverter
will
be
mounted.
