In
case
of
insufficient

energy
and
black
out,
the
whole
energy
stored
in
batteries
face
emergency

Thanks
to

is
possible
to
notice:
charge

‐
In
case
of
stand

installations,
the
back

extension
can
be
replaced
by
a
generating
set
on
the
AC

input
connection;

‐
Other
renewable
energy
sources
with
dedicated
charge
controller
can
be
used
for
charging
the
battery,
with
direct
connection
to
the
battery.
In
this
situation,
Leonardo
System
will
use
this
additional

available.
EXTERNAL
PROTECTIONS
AC
protections
(not
included)
Leonardo
System
1kW/1500/24
S
has
an
AC
–OUT
output
line
and
an
AC
–IN
input
line.
In
addiction
the
device
has
a
NEUTRAL
conductor
of
the
grounding
connection
–
TT
system.
The
AC
‐
OUT
output
line
can
be
protected
through
a
differential
magneto
thermal
breaker
(AC
type),
with
rated
current
In=16A
and
differential
current
Id=0,03A.
Also
the
AC
‐
IN
input
line
can
be
provided
with
a
differential
magneto
thermal
breaker
(AC
type),
with
rated
current
In=16A
and
differential
current
Id=0,03A.
(Please
note
that
in
general
this
kind
of
breaker
is
already
included
in
residence
control
panel.)
DC
protections
After
assembling
and
connecting
the
battery
bank
is
possible
to
assembly
the
protection
fuse
of
the
battery
on
the
positive
pole.
Through
the
connection
of
the
negative
pole,
the
inverter
will
be
activated.
NOTE:
Assembling
accessories
of
the
fuse
battery
are
suitable
for
batteries
with
fixing
terminals
type
M8.
In
case
of
different
diameter,
it
is
not
possible
to
use
the
accessories
supplied.
Connection
to
the
negative
pole
of
the
inverter
might
cause
flashes.
They
are
normal
considering
the
charge
of
the
inverter
input
condensers.
