Generally while at a marina the optional shore power should be set to charge
the house batteries continually. While living on the boat it will generally be
necessary to run one motor for at least one hour every day to recharge the
house batteries. While unattended the two 125W Solar Panels will generally
provide sufficient power to run either refrigeration or freezer units continually.
The batteries banks are switched “on” by a Battery Switches located in the port
Navigation area. The House Battery switch must be on for any 12VDC facility
except automatic bilge pumps. The Start Battery Switch must be “on” to start
and run either motor. The Emergency Parallel Battery Switch combines both
House and Start battery banks for emergency starting only and should be
normally “off”.
Switch Panels
The 12V DC Switch Panel includes combined on/off switches and automatic
circuit breakers. All Circuit Breaker Switches are individually labelled. To
increase reliability and simplify trouble shooting all circuit wiring is run directly
between electrical devises avoiding the use of intermediate junction boxes. A
schematic circuit diagrams are included in this manual.
WARNING: If more than one Electric Winch is used at the same time the
100A Circuit Breaker located below the Electrical Distribution Panel in the
Navigation area may trip.
The optional 110/240V AC Switch Panel and wiring uses Nth America or
Australian Standard wiring and separation. General Purpose Outlets have
automatic Earth Leakage Detection and through the hull Earth Plate connection
with the Shore Power option.
Battery Charging
Each Motor has an independently Regulated 80A Alternator directly connected to
the 700 CCA Start Battery through the Start Battery Switch.
WARNING:
To avoid Engine Alternator damage the Start Battery Switch must
be “on” at all times a motor is running.
The 700 CCA Starting Battery is recharged whenever either motor is running.
Only when the Cranking Battery is fully charged to approximately 13.2 volts a
Voltage Sensitive Relay diverts the charging current to the House Battery Bank.
This highly reliable redundant charging facility shares the load to provide
whatever the Battery will absorb up to a maximum 160A. Note that high current
usage devices such as Electric Anchor Winch are best operated with motor
