Stand-By Mode
Stand-by mode is activated by pressing the ON/
OFF button when shore power is connected to the
boat. Press the button once to turn stand-by mode
on. Press the button again to turn it o.
This mode is indicated by the “plug” LCD and the
display panel being illuminated. In this mode,
power for the loads connected to the inverter comes
from shore power. In the event of shore power
interruption, the inverter will switch automatically
to inverting mode to power the grill from the house
batteries. When shore power is restored, the invert-
er will automatically switch back to shore power.
Continuous DC draw from the house batteries is 1
Amp in this mode; which may discharge batteries
if they do not have an external source of charge.
Inverting Mode
Inverting mode is activated by pressing the ON/
OFF button when shore power is not connected to
the boat. Press the button once to turn inverting
mode on. Press the button again to turn it o.
This mode is indicated by the “battery” LCD and
the display panel being illuminated. AC power for
the grill is supplied by the house batteries. The unit
will automatically switch back to standby mode if
AC power becomes present.
When no shore power is connected and inverter
mode is activated, the inverter provides modied
sine wave, 120 volt AC power to the grill. In this
position the inverter will continue to supply AC
power until the house batteries are depleted. In
the OFF position the inverter draws no current from
the batteries.
Fault Conditions
The wrench symbol illuminates red when the in-
verter is in fault condition. The LCD display on the
inverter will provide a full fault message.
Typical faults are; battery over voltage, low battery
voltage, output overload or an over temperature
condition. Refer to the inverter operating manual
for more information on faults
.
General Inverter Operation
Inverters draw a substantial amount of current
from the house batteries when in inverter mode.
It takes approximately 20 amps 12 volt DC current
to provide 2 amps 120 volt AC current. Most grills
draw 10 to 11 AC amps. Therefore, you should
limit grilling time to 30 minutes when no shore
power is available.
In situations requiring a grilling time longer than
30 minutes, the engines can be started to charge
the batteries, if safe to do so. Use the following
procedure to charge the batteries with the engine
alternators.
• Make sure the engines are in neutral and no
one is in the water near the boat.
• Check the water depth at the engines. There
should be enough water to lower the engines
enough to completely submerge the cavitation
plate without the skeg touching the bottom.
• Start both engines and raise engine speed to
1000 RPM.
When the house batteries are depleted to 10.5 to
11 volts, an alarm will sound. When voltage drops
to 10 volts, the inverter will automatically shut-
down. You should avoid allowing battery voltage
to drop to alarm and shutdown levels. Low battery
voltage will damage battery cells and signicantly
shorten battery life.
DEPLETING 12 VOLT BATTERIES BELOW 10.5 VOLTS WILL
DAMAGE BATTERY CELLS AND SIGNIFICANTLY REDUCE
BATTERY LIFE. TO PRESERVE THE HOUSE BATTERIES,
ALWAYS SHUTDOWN THE GRILL WHEN THE INVERTER
ALARM SOUNDS. RECHARGE THE BATTERIES AS SOON
AS POSSIBLE.
