Connecting
the
PV
Strings
PV
Strings
connection
needs
below
prerequisites
;
otherwise
,
an
electrical
shock
can
occur
.
PV
modules
generate
electric
energy
when
exposed
to
sunlight
and
can
create
an
electrical
shock
hazard
.
Therefore
,
when
connecting
the
PV
modules
,
shield
them
with
opaque
cloth
.
Before
connecting
DC
input
power
cables
,
ensure
that
the
voltage
on
the
DC
side
is
within
the
safe
range
and
that
the
DC
SWITCH
on
the
inverter
is
OFF
.
Otherwise
,
high
voltage
may
result
in
electric
shock
.
When
the
inverter
is
grid-tied
,
it
is
not
allowed
to
maintain
DC
input
power
cables
,
such
as
connect
or
disconnect
a
string
or
a
module
in
a
string
.
Only
after
the
inverter
enters
in
shutdown
mode
,
it
is
allowable
for
preceding
DC
input
power
cables
maintenance
.
Grounding
the
PV
Strings
needs
below
prerequisites
;
otherwise
,
a
fire
can
occur
.
PV
modules
connected
in
series
in
each
PV
string
must
be
of
the
same
specifications
.
The
maximum
open
-
circuit
voltage
of
each
PV
string
must
be
always
lower
than
or
equal
to
its
permitted
range
.
The
maximum
short
circuit
current
of
each
PV
string
must
be
always
lower
than
or
equal
to
its
permitted
range
.
The
positive
and
negative
terminals
of
PV
modules
must
be
connected
to
the
positive
and
negative
DC
input
terminals
of
the
inverter
respectively
.
During
the
installation
of
PV
strings
and
the
inverter
,
the
positive
or
negative
terminals
of
PV
strings
cannot
be
connected
with
short
circuit
.
