Inverters
Installations
in
most
US
jurisdictions
are
subject
to
NFPA
70,
known
commonly
by
electricians
as
the
National
Electric
Code
(NEC).
The
NEC
requires
that
the
inverter
be
connected
to
a
dedicated
circuit
and
no
other
outlets
or
devices
may
be
connected
to
this
circuit.
The
NEC
also
imposes
limitations
on
the
size
of
the
inverter
and
the
manner
in
which
it
is
connected
to
the
utility
grid.
See
applicable
revision
of
the
NEC
for
more
information.
It
is
the
installer’s
responsibility
to
follow
all
applicable
electric
codes.
2.1
Clearance
Requirements
The
ambient
temperature
must
be
between
–40
o
F
and
+130
o
F
(–40
o
C
and
+55
o
C)
for
full
power,
continuous
operation.
The
inverter
will
automatically
reduce
power
or
may
shut
down
to
protect
itself
if
ambient
air
temperature
at
the
intake
rises
above
130
o
F
(55
o
C).
The
cooling
air
exhausts
at
the
rear
and
bottom
of
the
enclosure.
Nothing
should
block
the
4
inch
clear
space
under
the
enclosure
between
the
mounting
feet.
A
minimum
distance
of
8
inches
(200mm)
must
be
clear
behind
the
inverter
for
rear
cooling
air
exhaust.
12
inches
(300mm)
is
recommended.
A
minimum
distance
of
12
inches
(300mm)
must
be
clear
above
the
inverter
for
ventilation.
Make
sure
the
AC
and
DC
disconnect
switches
are
accessible
during
operation
and
that
all
doors
may
be
fully
opened
for
maintenance.
Install
the
inverter
in
an
accessible
location
following
applicable
electrical
codes
for
working
clearance
requirements
and
proximity
to
other
equipment.
If
you
are
installing
the
inverter
in
an
electrical
closet,
the
air
circulation
must
be
sufficient
for
heat
dissipation.
Provide
external
ventilation
to
maintain
an
ambient
condition
of
less
than
130
o
F
(55
o
C).
The
ambient
temperature
should
be
kept
as
low
as
possible
at
all
times
for
optimal
inverter
operation
and
life.
