must go to the office station and turn on the gang circuit for the generator in order to
bring it on line. The Xantrex “Power Share Selector should be set for 50amps to provide
maximum charging from the generator. The generator is preset to run for two hours and
then will shut down. You can always shut it down manually at any time you wish, after
the batteries are recharged.
If the DC volts read less than 12.0 volts you will need to run
the generator to recharge the batteries, unless you will be underway soon.
INVERTER/CHARGER
The inverter is intended to provide 110 volt AC power to small appliances when you are away
from shore power, or do not want to use the generator. The inverter converts 12-volt battery
power into 110 volt AC power. The XANTREX INVERTER/CHARGER panel is located at the
office station directly in front toward the left, as you are sitting at the table. While away from
shore power, if you want 110 AC power:
1.
Turn the Inverter ON at the INVERTER/ CHARGER panel by pushing where it says
INVERT. A green indicator light will come on inside the box labeled INVERT. With
this green light illuminated, the inverter will power selected 110-volt appliances and
outlets.
2.
Confirm that the following circuits on the AC panel at the office station are ON:
•
Microwave, Galley Outlets, TV, Head, and Ice Maker (if desired).
3.
Monitor your usage
.
If too many appliances are on at the same time, you may
trip the Inverter/charger breaker on the AC panel. If this happens, unplug or turn off one
or more appliances and reset any tripped breakers on the AC SHOREPOWER panel at
the office station.
4.
Do not attempt to power portable electric heaters through the inverter
! When AC
power is available from shore power or from the generator, the inverter/charger
automatically charges the house batteries. However, when leaving the boat, go to the
office station and observe the Xantrex inverter panel. Check the green LED light is not
illuminated on the INVERT button. If it is, push the button and the light and inverter
will turn OFF. This should be done so if shore power fails, an onboard appliance (e.g. a
coffee maker, or a heater) will not draw down the batteries. The real danger is that the
bilge pumps depend on battery power, and if they die, the bilge pumps die with them.
GENERATOR
Mariah has an 11.5 kw Onan generator. You may need to use it if you have overnight anchorages
of a day or more and have used the inverter to power AC systems. If you have been connected to
shore power or are running the engine 5-6 hours a day, you should have adequate battery power.
However
, if the DC panel voltmeter #2 battery bank (house batteries) gets down to 12 volts, and
you do not plan to be underway soon, run the generator to recharge the batteries. It is harmful to
the batteries to discharge below 12 volts.
Note: If the generator auto start panel is in the “enable” position it will start the generator when
the battery level reaches approximately 11.8 volts. Should the generator start on its own you will
need to go to the AC power panel and select the generator gang breaker to “ON” in order to
charge the batteries. Also ensure the xantrex power-share panel is set at 50 amps for maximum
charging rate from the generator.
1.
The generator panel is located in the center/right of the AC panel at the office station.
There is a rocker switch on the left side of the panel used to start the generator engine.
Hold the top of the switch DOWN in the Start/Preheat position for approximately 10 to
20 seconds. When preheat is complete the engine will start and you can release the
