A 12-volt DC Fusion stereo is mounted in
the cabinet below the TV monitor. The
Fusion stereo has touch-screen
operations to select AM/FM radio, or
input with Blue Tooth or Apple Airplay.

Inverters/Charger
Management of the electrical power systems is an important topic. There are two electrical
systems on board. The 120-volt AC power is provided when connected to shore power or, when
the generator is running. Electrical power can also be stored in batteries that provide 12-volt DC
power for a limited time. Monitoring the battery levels is imperative to keeping all the boat
systems operating normally. The rule of thumb is to begin charging the batteries when they
reach 12.2 volts. When the batteries are at 12-volts, they are a half capacity and below 12-volts
will shorten their expected lifespan. AC power can also be produced by inverting 12-volt DC
power to 120-volt AC power. The inverter is connected only to a few of the circuits. Electrical
power is distributed through the breaker panels which are on the ports side of the lower helm.
The upper portion of the distribution panel is for the 12-volt DC system and the lower half is for
the 120-volt AC system.

Shore power (50-amp, 240-volt)
The AC power system is like the electrical power at your home. When connected with shore
power the 120-volt AC system will have power; outlets and appliances will operate normally.
Arctic Star is set up for 240-volt 50-amp power supply needed to power the electric stove and
air conditioning system. Shore power is supplied through two 120-volt leads that are split in the
