GENERAL
The 50z’s electrical system may be more advanced than what you are accustomed to. It
combines 12volt DC with both 120volt and 220 volt AC power in several ways.
Most of the electrical components on your boat use DC power. 12 volt DC power is stored in three
8D 255 Ampere Hour House Batteries plus a 31G 105 Ampere Hour Start Batteries for each
engine and the genset, totaling 1080 Ampere Hours of capacity on the Triple IPS 600 #1.. This
battery capacity is replenished in 3 ways :(1) Alternator output from the engines when running (2)
From 110V 60cyle AC shorepower through the Victron Phoenix 3000 Inverter/Centaur
Charger or (3) From the Northern Lights 9KW Generator which outputs 110V 60-cycle power to
the charger.
120-volt AC power, typically found in homes, is supplied to the boat in 3 ways: (1) via 50
Amp or 30 Amp shore-power cords plugged into a shoreside receptacle (2) by an optional
generator or (3) by inverting DC power from a battery into AC power through the
Mastervolt Inverter. The AC components aboard your boat include the refrigerator/freezer,
cooktop, microwave, some TV components, the air-conditioning, water heater, inverter, and
receptacles (plug in AC equipment).
220-volt AC, the central panel of three, provides power to the 3-zones of chilled water air
conditioning, the Seakeeper Gyro Stabilizer and the water heater.
Both AC and DC electrical power sources are potentially dangerous. Do
not attempt to work on any part of your boat’s electrical system if you are not a qualified
marine electrician.
ELECTRICAL PANELS
There are two battery banks on your boat. The house bank consists of (3) 255Ah, absorbed-glass
mat (D8 AGM) batteries. The engine bank consists of two (or 3) 105Ah Group 31 AGM start
batteries which are also used to run the windlass. Whenever a charging source is present (either
from the battery charger or an engine-driven alternator)
both banks are automatically
charged. AGM batteries are essentially no-maintenance.
Do not attempt to open the batteries . Other than keeping them properly charged,
stored, and clean (especially between the terminals), there is virtually nothing you need to do to
them. The battery charger is factory set specifically for AGMs.
If the engine is not running, the batteries can be charged via the battery charger, which is
powered by AC electricity either from your generator or shore-power. It is important to read
and understand the inverter/charger manual to be sure that the unit is functioning as you
expect.
N e v e r a l l o w y o u r D C s y s t e m ’ s voltage to fall below 11.2 volts. Sensitive
electronics may fail to function. For this reason, it is advisable when leaving the boat to turn off
all loads, turn off heir respective circuit breakers, and turn off the main DC battery switches
and turn off the inverter on the unit itsel inside the starboard pilothouse settee locker on top of the fuel
tank..
24 Hour Circuits The only load that remains on when the battery switches are in the OFF
position are the “24 Hour” circuits (shown at right) which by-pass the panel circuit breakers and
are connected directly to the batteries.
