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 chap-
ter 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 invert-
er can be set to charge the batteries. Simply select the
charger mode on the inverter remote panel by pressing
the “CHARGER ON/OFF” button (Fig. 8.15). The green
“CHG” LED will illuminate and the LCD display will read
“CHARGING”.
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 connection exists between the alternator and bat-
teries 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 switch
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 switch
at the AC Panel.
Note: When paralleling shore power, one will need to use a
parallel shore power y-adapter cord.
8.2.10 Reverse Polarity
Each line on the AC Panel includes a LED display for
Reverse Polarity. If the Reverse Polarity light is dis-
played, it indicates a problem exists involving the ground.
The problem’s origin generally involves the power at dock
side or the shore power cord. However, a short in the
boat’s electrical system may exist between the main AC
Panel back to the shore power inlet.
To isolate the cause of the reverse polarity, one must trou-
bleshoot the possible factors for determination. Actions
may include testing an alternate shore power source or
swapping shore power cords. If the problem appears to
be boat side, have your system checked by qualified and
competent electrical service personnel.
8.3 AC System Components and Operation
8.3.1 Outlets Breaker (Line 1)
The 120V (230V option) outlets installed throughout your
boat are controlled by a 15 amp (10 amp) toggle switch
breaker labeled “OUTLETS” on the AC panel (see Fig.
8.19 for outlet locations). In addition, some outlets have
