Whistler inverters convert low voltage, direct current (DC)
to 110 volt alternating household current (AC). The AC
output is called “modified sine wave”. See “Technical
Operating Principles” section for more information.
Depending on the model and its rated capacity, Whistler
inverters draw power either from standard 12 volt automo-
bile and marine batteries or from portable high power 12
volt sources.

IMPORTANT INFORMATION
INVERTER BASICS
Important Information About Your New Whistler
Inverter.
This manual will provide you with directions for the safe
and efficient operation of your Whistler Inverter. Read the
manual carefully before using your new Whistler inverter
and keep the manual on file for future reference.
Getting Started
Power equipment and appliances which operate with motors
or tubes require an initial surge of power to get them up and
running. This power surge is referred to as the "starting load"
or "peak load." (By comparison, electrical devices such as
standard light bulbs do not require a large starting load).
Once the equipment or appliance has been powered up, it
settles down to a slower pace and requires far less electrical
power to operate. This lower power requirement is referred
to as the "continuous load."
Notes:
Your Whistler inverter is designed to operate from a 12 volt
power source only. Never attempt to connect your
Whistler inverter to any other power source, including any
AC power source.
In order to ensure that the capacity of your Whistler inverter
is sufficient to meet the required start up load, you must first
determine the power consumption of the equipment or
appliance you plan to operate.
•
The length of the supplied cables is matched for the
current needed by the inverter. Making this cable
longer will make the inverter less efficient and may
cause the cables to heat up.
Power consumption is rated either in wattage or in amperes,
and information regarding the required "watts" or "amps"
generally is stamped or printed on most appliances and
equipment. If this information is not indicated on the appli-
ance or equipment, check the owner’s manual. Contact the
appliance or equipment manufacturer to determine if
the device you are using (TV’s, battery re-charger, com-
puter, etc.) is compatible with a modified sine wave.
•
•
Do not attempt to lengthen the supplied power
cables.
110 volts can be lethal. Improper use of your Whistler
inverter may result in property damage, personal
injury or loss of life.
•
Not reccommended for use with medical equip-
ment. Check with the appliance manufacturer for
compatibility with modified sine wave inverters.
Some appliances may not work well, not at all or be
damaged. For more information on compatibility issues,
If the power consumption is rated in amps, multiply the num-
ber of amps by 110 (AC voltage) to determine the compara-
ble wattage rating. Induction motors, as well as some televi-
sions, may require 2 to 6 times their wattage rating to start up.

INVERTER BASICS
INVERTER BASICS
Don’t Push It.
If a piece of equipment or an appliance will not operate, first
confirm that the inverter has been properly connected to
the 12 volt power source (See "Making The Connection"). If
all connections have been properly made, turn the inverter
rocker switch ON (l), OFF (O) and ON (l) again in quick suc-
cession. If this procedure is unsuccessful, it is likely that the
inverter does not have the required start up capacity to
operate the equipment or appliance in question.
Although your Whistler inverter has the capacity to provide
power output (excess current) equal to approximately two
times its rated wattage capacity for a very brief period, it is
designed to operate equipment and appliances with start
up load wattage ratings no higher than its own maximum
continuous wattage rating.
For example, the 800 model has a maximum continuous rat-
ing of 800 watts. Although this model has the capacity to
briefly provide up to 1600 watts of power (that is, excess cur-
rent), it is designed to operate equipment and appliances
with start up load requirements of 800 watts or less.
Note:
•
Most heat generating appliances require start up
loads in excess of 1000 watts and the inverter will not
operate such appliances as coffee makers, irons, hair
dryers or heaters.
Consequently, if the start up load rating of your equipment
or appliance is the same or approximately the same as the
maximum continuous rating of the inverter, the inverter will
attempt to start loads above the continuous rating for up to
10 seconds.
To determine whether your inverter will operate a particular
piece of equipment or appliance, run a test. The inverter is
designed to shut down automatically in the event of a
power overload. Testing appliances and equipment with
start up load ratings comparable to your inverter wattage
rating will not damage it.

OPERATION
OPERATION
Making the Connection.
Note:
This inverter is designed to connect to your 12 volt battery
by the supplied #8 gauge cables.
•
•
Loose connections can result in a severe decrease in
voltage which may cause damage to the wires and
insulation.
Failure to make proper connection between the
inverter and the power source will result in reverse
polarity. Reverse polarity will blow the internal fuses in
the inverter and may cause permanent damage to the
inverter. Damage caused by reverse polarity is not
covered under the Whistler warranty.
1. Make certain that the inverter’s rocker switch is in the
OFF (O) position.
2. Connect the cables to the power input terminals at
the rear of the inverter and tighten the screws to make
a secure connection. Do not use tools to tighten
these screws.
3. Connect the cable from the (BLACK) Negative (-) ter-
minal on the inverter to the Negative (-) terminal on
the 12 volt power source. Make certain the connec-
tion is secure.
4. Confirm that the cable you have just installed is prop-
erly connected. Specifically, make certain that the
cable is connected to the Negative (-) terminals on
both the inverter and the 12 volt power source.
5. Connect the cable from the (RED) Positive (+) terminal
on the inverter to the Positive (+) terminal on the
power source.
•
•
Making the connection between the Positive (+) ter-
minals may cause a spark as a result of current flowing
to the capacitors in the inverter. This is a normal
occurrence. Due to the potential for sparking, how-
ever, it is extremely important that both the inverter
and the 12 volt battery be well removed from any pos-
sible source of flammable fumes or gases.
Failure to heed this warning could result in fire or
explosion.
If the supplied cables are too short to allow for place-
ment of the inverter in a desired location, the inverter
may be connected to the power source using a #4
wire, up to 12’ - #2 wire for longer lengths. The steps
outlined for making the connection and the related
safety precautions remain unchanged.
6. Turn the inverter rocker switch to the ON (I) position.
The LED Indicator Light should glow GREEN confirm-
ing that there is power running to the inverter.

OPERATION
OPERATION
7. Turn the inverter rocker switch to the OFF (O) position.
(The GREEN LED Power Indicator light may “blink”
briefly and/or the internal audible alarm may make a
momentary “chirp”. This is normal).
8. Confirm that the equipment or appliance to be oper-
ated is turned off. Plug the equipment or appliance
into one of the three AC receptacles on the front
panel of the the inverter.
Important Information on Battery Chargers
Using your inverter to recharge units designed to charge such
portable equipment as power tools, flashlights, video cameras
and laptop computers may cause damage to the inverter
or the charging unit. Check with the appliance manufacturer
for compatibility with sine wave inverters if you’re unsure.
Although we advise against it, if you attempt to recharge a
charging unit, monitor the temperature of the charging unit
for approximately 10 minutes. If the charging unit becomes
unusually warm, disconnect it from the inverter immediately.
9. Turn the inverter to the ON (I) position. Turn on the
equipment or appliance.
Note:
•
As indicated in Step 7 above, the audible alarm may
make a momentary “chirp” when the inverter is
turned OFF (O). The same alarm may also sound
when the inverter is being connected to or discon-
nected from the 12 volt power source. Again, this is
normal.
Don’t Blow A Fuse.
This inverter is equipped with three 35 amp spade type fuses.
With reasonable care, it should not be necessary to replace
the fuse(s) in your inverter. We have included an “open fuse”
monitor on the DC panel.
•
•
The use of an extension cord from the inverter to the
appliance or equipment being operated will not sig-
nificantly decrease the power being generated by the
inverter. For best operating results, the extension
cord should be no more than 50 feet long.
Check frequently to ensure that the input and output
connections are secure. Loose connections may dam-
age the inverter, the power source, or may generate
excessive heat.
Most blown fuses are the result of reverse polarity or a short
circuit within the appliance or equipment being operated. If
the fuse(s) does blow, turn off and disconnect the appliance
or equipment from the inverter immediately, repair the
related problem and replace the fuse(s). The internal fuses
are replaceable, however, only an electronically knowledge-
able person should attempt fuse replacement.

ADDITIONAL FEATURES
OPERATION
Note:
Automatic Shut Down & Related Safety Features.
•
Make certain to correct the source of the overload
which caused the blown fuse before turning your
inverter back ON (l).
Each Whistler inverter model has an unique LED Indicator
warning light system which operates in conjunction with
the automatic shut down feature. These indicator lights
operate as follows:
The Power Source.
GREEN LED:
RED LED:
System ready.
When the engine is off, most batteries will provide ample power
supply to the inverter for one to two hours. The actual length
of time is a function of several variables including the age and
condition of the battery and the power demand being placed
on it by the equipment being operated with the inverter.
System overload/automatic shut down.
YELLOW LED: Open fuse.
Your inverter will shut down automatically when any of the
following problems occur:
If you are using the inverter while the engine is off, we
recommend you start the engine every hour and let it run for at
least 10 minutes to recharge the battery. We also recommend
that the device plugged into the inverter be turned off before
turning over the engine.
1. The power input from the battery drops below
9.5 volts.
2. The power input from the battery exceeds 16 volts.
3. The continuous draw of the appliance or equipment
being operated exceeds the design parameters of the
inverter.
Although it is not necessary to disconnect the inverter when turn-
ing over the engine, the inverter may momentarily cease opera-
tion as the battery voltage decreases. When the inverter is not
supplying power, and turned on, it draws very low <0.40 A ).
The inverter is equipped with the following additional safety
features:
1. Thermal Cut Off:
Automatic shut down if internal temperature exceeds
safe design parameters.

CARE AND MAINTENANCE
ADDITIONAL FEATURES
To maintain your inverter in proper working condition, note
the following important safety precautions:
2. Low Battery Voltage Alarm/Shutdown Protection
a) When the input voltage from the 12 volt power source
drops below 10.5 volts, an audible tone will be heard.
This is the low battery voltage alarm.
•
MOISTURE. Keep the inverter dry. Do not expose it
to moisture. Do not operate the inverter if you, the
inverter, the device being operated or any other sur-
faces that may come in contact with any power
sources are wet. Water and many other liquids can
conduct electricity which may lead to serious injury or
death.
b) The inverter will automatically shut down when the
input voltage drops below 9.5 volts. This protects the
battery from completely draining.
In the event of automatic shut down or continuous audible
alarm, turn the inverter rocker switch to the OFF (O) position
until the source of the related problem has been identified
and resolved.
•
HEAT. For peak efficiency, the ambient air tempera-
ture should be between 50° and 80° F. Avoid placing
the inverter on or near heating vents, radiators or
other sources of heat. Do not place the inverter in
direct sunlight.
Wall Mounting:
Whistler inverters have provisions for wall mounting;
slotted holes allow for easy wall mounting of the unit.
•
•
VENTILATION. In order to disperse the heat generat-
ed while the inverter is in operation, keep it well venti-
lated. While in use, maintain several inches of clear-
ance around the top and sides of the inverter.
Some Powerful Advice.
Your Whistler inverter will work best when placed on a rea-
sonably flat surface. The floor or seat of your car or truck both
are good locations.
FUMES & GASES. Avoid using the inverter near
flammable materials. Do not place the inverter in
areas such as battery compartments, where fumes or
gases may accumulate.
When driving with the inverter in operation, make certain that
neither the inverter nor the power cords will impede safe
operation of your vehicle. Keep the unit and all cords clear of
the steering wheel, gas, brake and clutch pedals and gear
shift.
In Review.
•
Never attempt to operate your Whistler inverter from
any power source other than a 12 volt battery or series
of batteries that total 12 volts.

OPERATING PRINCIPLES
OPERATING PRINCIPLES
For You Technical Types.
assume that the measured waveform will be a pure sine
wave.
1. Basic Operating Principles:
Consequently, these meters will not read the RMS modified
sine wave voltage correctly and, when measuring your
Whistler inverter output, the meters will read about 20 to 30
volts too low. To accurately measure the output voltage of
your inverter, use a true RMS reading voltmeter such as a
Fluke 87, Fluke 8060A, Beckman 4410, Triplett 4200 or any
multimeter identified as "True RMS."
Whistler inverters work in two stages. During the first stage,
the DC to DC converter increases the DC input voltage from
the power source (e.g. a 12 volt battery) to 145 volts DC. In
the second stage, the high voltage DC is converted to 110
volts (60 Hz AC) using advanced power MOSFET transistors
in a full bridge configuration. The result is excellent overload
capability and the capacity to operate difficult reactive loads.
The output waveform resulting from these conversions is a
"quasi-sine wave" or a "modified sine wave" as shown below
For more information on inverters see our Inverter FAQ
This stepped waveform is similar to the power generated by
utilities and has a broad range of applications.
The modified sine wave produced by
your Whistler Inverter
A true sine wave typical of home AC outlet.
The modified sine wave produced by your Whistler inverter
has a root mean square (RMS) voltage of 110 volts. The
majority of AC voltmeters are calibrated for RMS voltage and
