there
will

In
this
condition
the
power
man_
agement
system
will
limit
the
total
generated
power
to
one
genera_
tor.
This
will
be
an
environmentally
friendly
profile
where
the
load
of
one
generator
is
limited
to
an
op_
timum
95yo.
When
required
the
power
manage_
ment
system
will
temporarily
re_
duce
the
Ioad
of
some
consumers
like
the
HVAC
system
or

This
is
the
extended
version
of
the
previous
condition
with
the
HVAC
systems
for
crew
and
guests
at full
capacity.
The
actual
power
con_
sumption
will
depend
on
the
out_
side
temperature.
The
power
management
system
will
control
the
total
generated
power
and
will
normally
connect
one
or
two
generators.
The

Load balance small
sailing-yacht
Although
not
obvious,
a small
sail-
ing
boat
will
also
require
a load
bal-
ance
of
some sort.
A single line
for a
yacht
like
this
is
shown
in
chapter
33. This
yacht
has
a
shore
supply,
a
dynamo
on the
main
engine
and a solar-cell
and/
or
a wind-
generator.
In
port
the
primary supply
will
be
the shore
supply, taking
care
of
heating,
cooking, ventilation
and
battery
charging,
When
sailing there
are
two modes:
-
running
on the engine
and
charging
the
batteries
with
the
dynamo.
sailing
on
wind
power
and charg-
ing
the
batteries with
the wind
generator
in combination
with
the solar cells.
The
capacity
of the
solar
cells
and
the wind
generator
is very
limited
when
compared
to
the
dynamo
on
the engine
and
heating
and/
or
cooking
with the
engine
off
may
very
well
be impossible.
