2.3.
Operation
2.3.1.
Normal
The
rectifier
and
charger
will
get
the
AC
commercial
power
and
convert
it
to
DC,
and
then,
send
it
to
inverter
for
the
reverse
to
AC
and
to
battery
for
charging.
The
filtered
AC
power
from
inverter
will
be
supplied
to
the
load
without
interruption.
2.3.2.
Power
Outage
When
commercial
power
fails,
the
battery
starts
to
let
out
the
reserved
DC
power
to
inverter
and
it
continues
to
feed
the
load
during
the
power
outage
for
the
defined
time
period.
2.3.3.
Power
Recovery
When
the
commercial
power
is
recovered,
the
battery
stops
to
feed
and
starts
to
recharge.
At
the
same
time,
the
commercial
power
passes
through
the
normal
routine.
2.3.4.
Internal
Failure
&
Over-load
The
output
voltage
and
frequency
of
inverter
are
synchronized
with
the
commercial
power
supply
at
all
times.
Thus,
in
case
of
internal
failure
or
over-load,
the
static
switch
transfers
power
to
bypass
feed
and
the
synchronized
power
is
constantly
fed
to
the
load.
