the nav station near the optional VHF radio and chart
table light (Fig. 8.13).
8.2.7.1 Turning on the Inverter
Turn on the desired battery selector switches (see
DC Electric System chapter in this manual).
Turn on the inverter remote panel at the navigation
station.
Turn on the “AC Main” switch breaker at the AC
Panel.
Turn on the appropriate appliance breaker on AC
panel.
NOTE: Anticipate an approximate 15 second delay when
using the inverter.
NOTE: Consult the inverter manufacturer’s OEM manual for
inverter operation, care and maintenance.
Please note, it takes 10 DC amps to create 1 AC amp.
If the battery voltage drops below 10.5V the inverter will
automatically shut down. Also the output of the inverter
is not capable of powering the water heater or air condi-
tioning system. Both should be powered by shore power
or the generator.

8.2.7.2 Powering DC Panel and AC Panel
Simultaneously When Using the Inverter
When shore power is not connected:
Turn on the inverter as outlined above.
Switch on the “DC Main” switch breaker at the Battery
Switch Panel (see DC Electric System chapter in this

manual).
Turn on breakers at the DC Panel for the desired DC
components.
8.2.7.3 Built in Inverter Transfer Switch
If shore power or generator is supplying power, the invert-
er automatically transfers this power to the AC Panel and
bypasses the invert mode capabilities.
8.2.7.4 Charging the Batteries from the Inverter
If shore power or generator is supplying power, the
inverter can be set to charge the batteries. Simply select
Charge mode on the inverter remote panel.
NOTE: When leaving boat unattended, be sure the Invert
selection on the remote panel is “OFF”. This way, if shore
power is lost for any reason, the inverter will be prevented from
converting 12V DC to AC voltage and drain the batteries.
8.2.8 Engine Alternator Operation
Batteries can also be charged by the engine alterna-
tor. This is the same basic system as an automobile.
A direct wiring connection exists between the alternator
and batteries resulting in immediate charging when the
engines are running. For additional information regarding
the engines, please refer to Engines and Transmissions
chapter within this manual.
8.2.9 The Parallel Breaker and Optional Air
Conditioner Using Shore Power
Some dock side shore power sources are of sufficient
amperage to power both the optional air condition and the
standard AC system.
To power the optional air conditioner from a single shore
power cable, perform the following steps:
Switch off the “Air Conditioner” breaker switches at
the AC Panel.
Switch on the AC Panel’s “Parallel” toggle switch
breaker. The toggle switch is managed by a slide-bar
stopper. This stopper will only allow source power to
be paralleled from either 1 shore power line with 50
amps or from the generator.
Switch on the “Air Conditioner” breaker switches at
the AC Panel.
