Chapter 3: Electrical Installation
Details for electrical installation in accordance with the IEC61730-1.
Installation
The
maximum
system
voltage
of
the
Smart
Module
60-cell
Mono
PERC
with
Integrated
Power
Optimizer
(module SPVxxx-60MMJ)
is
1000
V
.
T
he
maximum system voltage of the
Smart
Module
Half-cut
Cell
Mono
PERC
with
Integrated
Power
Optimizer
is
1500
V
(module SPVxxx-R60LWMG) and 1000V
(module SPVxxx-R60LBMG)
.
The
power
optimizers
regulate
the
string
voltage
at
a
constant
level,
regardless
of
string
length
and
environmental
conditions.
Under
normal
conditions,
a
module
might
produce
more
current
and/or
voltage
than
reported
at
standard
test
conditions
(1)
.
The
requirements
of
the
National
Electrical
Code
(NEC)
in
Article
690
shall
be
followed
to
address
these
increased
outputs.
In
installations
not
under
the
requirements
of
the
NEC,
the
values
of
Isc
and
Voc
marked
on
this
module
should
be
multiplied
by
a
factor
of
1.25
when
determining
component
voltage
ratings,
conductor
capacities,
over
current
device
ratings,
and
size
of
controls
connected
to
the
PV
output.
Each
series-connected
string
of
modules
shall
be
provided
with
the
maximum
series
overcurrent
protective
device,
specified
as
15A
for
the
Smart
Module
60-cell
Mono
PERC
module
with
Integrated
Power
Optimizer
series
and
20A
for
the
Smart
Module
Half-cut
Cell
Mono
PERC
Module
with
Integrated
Power
Optimizer
series.
Use a cable with a cross section of 4 mm
2
(12AWG) that can withstand the maximum
possible
system
open-circuit
voltage
and
make
sure
that
all
connections
are
safe
and
tight.
The
cable
minimum
bending
radius
should
be
43
mm.
Bypass
diodes
are
included
in
module
junction
boxes
to
avoid
decreased
module
performance.
Check
the
relevant
specifications
for
the
specific
diodes
of
the
junction
box.
For
the
smart
module
electrical
data
and
temperature
coefficients
,
refer
to
the
technical
specification
sections
in
this
manual.
