Preparation
and
Inverter
Placement
The
inverter
is
comprised
of
a
rainproof,
industrial
enclosure
containing
electrical
and
electronic
components
and
AC
and
DC
integrated
disconnecting
means.
NOTE:
If
the
inverter
is
mounted
outside,
ensure
that
the
enclosure
and
disconnect
switch
doors
remain
closed
during
the
installation
process
in
case
of
rain
or
snow.
Leaving
these
doors
open
during
installation
will
void
the
warranty.
NOTE
:
It
is
recommended
to
store
the
inverter
indoors
before
installation.
If
the
inverter
is
to
be
stored
outdoors
for
more
than
one
month
before
being
installed
and
commissioned,
care
must
be
taken
to
avoid
condensation
inside
the
unit.
Removing
the
protective
shipping
wrap
and
placing
a
small
space
heater
inside
the
unit
minimizes
the
amount
of
condensation
that
can
occur
during
onsite
outdoor
storage.
Once
operational,
the
inverter
will
generate
its
own
heat
to
prevent
condensation.
Criteria
for
Device
Mounting:
Because
the
power
electronics
are
within
the
rainproof
enclosure,
the
inverter
can
be
mounted
outdoors.
The
longest
life
for
the
inverter
can
be
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
and
use
the
maximum
allowable
cable
size.
Avoid
installation
in
close
proximity
to
people
or
animals,
as
there
is
an
audible
high
‐
frequency
switching
noise.
Install
the
inverter
in
an
accessible
location
following
local
electric
codes
for
enclosure
and
disconnect
switch
door
clearances
and
proximity
to
other
equipment.
Although
the
inverter
is
designed
to
function
at
full
power
continuously
in
up
to
55
o
C
ambient
temperature,
for
longest
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
metal
sun
‐
shield
is
recommended.
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.
CAUTION:
Be
sure
to
verify
load
capacity
of
floor,
roof
or
pad,
and
ensure
that
lifting
equipment
has
adequate
lifting
capacity
to
lift
the
unit.
