will still accept a charge from the battery charger. Leave “Inverter/Charger” breaker ON on AC
Panel 1. If you are leaving the boat plugged into shore-power and you wish to turn off all DC
loads, but still be able charge batteries, leave the house switch ON and turn off the main DC
disconnect breaker on the DC panel.
Disconnecting shore power with INVERT LED ON will cause discharge of
the house battery bank.
In the event of a dead or weak engine battery, the parallel battery switch can be used to combine
the house bank to the engine start bank. All three switches must be ON for this function. This is
recommended only as a last resort- if shoreside or genset charging is available, use that to re-
charge the start batteries.
6.3
AC SYSTEM (Optional)
The AC system exists to power such
items as a Cooktop, Microwave,
Entertainment System, AC Outlets,
Air-Conditioning and Water Heater.
There are three ways to supply AC
power to these appliances/systems:
(1) You can plug a 30-amp shore
power cords into a shore-power
supply, depending on which items you
want to power; (2) the generator can
be used; or (3) the house batteries
can supply DC power to the Inverter
which converts it into AC power. The
main AC disconnect breakers (top of
the AC panel) must be ON for shore-
power AC to supply the boat’s AC
power. . To use the inverter, (1) the
house battery selector switch must be
ON and (2) the inverter breaker on the
AC panel must be ON. Refer to the
inverter/charger manual for more
information
If the generator (optional) is being
used in lieu of shore-power, the
owner must be aware that using too
many AC appliances at once may
cause a breaker to blow. Avoid using
major appliances simultaneously.
As mentioned, the generator
(optional) can be used to create AC
power. The generator battery selector
switch must be ON and the generator
must be selected on the AC panel.
Refer to the manufacturer's manual
for more information regarding
the generator.
