CHAPTER 6
ELECTRICAL SYSTEM

The AC
Transfer
switch allows either Shore 1 or generator to power the AC Panel #2 circuits. If
this function is utilized, be aware that using too many AC appliances at once will cause a
shorepower breaker to blow.
AC Panel Shore 2 (aft or right half of panel) is designed for those items having too much load for
the batteries and inverter, thus requiring either shorepower or the generator to supply AC power.
The high amperage water heater and air-conditioning systems are best supplied with a
shorepower cord to stern INLET #2 which by-passes the inverter and goes right to AC Panel #2.
However, they can also be powered from shorepower Inlet #1 using the TRANSFER feature of
the panel so long as one doesn’t try to use the Microwave and/or Cooktop or both the Water
Heater and AC at the same time.
CHARGING
The main HOUSE battery switch can be switched OFF when the boat is not used,
and the batteries will still accept a charge from 120V SHOREPOWER through the battery
charger. Obviously, to keep the Refrigerator going, you’d have to leave the main HOUSE battery
switch ON as well as the Refrigeration breaker switch ON.
Leave “Inverter/Charger” breaker ON at AC Panel 1. Note green LCD “Charged” on Link 2000
must be ON. “Invert” LED light must be OFF. 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 top Main DC disconnect breaker on the DC panel.
Disconnecting shore power with INVERT LED left ON may cause discharge
of the house battery bank.

INVERTER/CHARGER
The 36z uses the Xantrex Freedom SW
3000 watt combination inverter/charger
(in a single unit). This remote panel has
its own manual, with which you should
become familiar or it may be down-
loaded from
www.xantrex.com
. This
unit is located over the starboard fuel
tank in the pilothouse settee locker.
When a supply of AC power is present
(from shore-power or generator), the
unit can charge both the house battery
bank, generator and the engine start
batteries. The Inverter/Charger breaker
(on the AC panel) should normally be
ON. If no source of AC power is
available, the inverter can use DC
power from the house bank to create AC power for items on AC Panel #1. If AC power becomes
available, either from shore-power or the generator, the inverter/charger transfers this power to
AC panel #1. In other words, your batteries will not be used to create AC power if either the
generator or shore-power #1 is active and the inverter breaker is ON.
