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 automobile  
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 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  
appliance or equipment, check the owners manual. Contact  
the appliance or equipment manufacturer to determine  
if the device you are using (TV’s, battery charger,  
computer, 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.  
Do not connect the inverters output to any other power  
source.  
If the power consumption is rated in amps, multiply the  
number of amps by 110 (AC voltage) to determine the  
comparable wattage rating. Induction motors, as well as  
some televisions, may require 2 to 6 times their wattage rating  
to start up.  
Not recommended for use with medical equipment.  
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,  
please visit our inverter FAQ page at  
For further information on the fundamental operating  
principles of Whistler inverters and related technical data,

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  
succession. 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 Pro-800W model has a maximum  
continuous rating of 800 watts. Although this model has the  
capacity to briefly provide more than its continuous power  
(that is, excess current), 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.  
The inverters USB Port does not support data  
communications.  
Consequently, if the start up load rating of your equipment  
or appliance slightly higher than the maximum continuous  
rating of the inverter, the inverter will attempt to start loads  
above the continuous rating.  
USB power is always on and independent of the  
inverters on/off switch.  
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 the inverter.

OPERATION  
Making the Connection.  
Note:  
This inverter is designed to connect to your 12 volt battery  
by the supplied #8 AWG 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.  
Making the connection between the Positive (+)  
terminals 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  
1. Make certain that the inverters 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 (-)  
terminal on the inverter to the Negative (-) terminal on  
the 12 volt power source.  
connection is secure.  
Make certain the

the inverter and the 12 volt battery be well removed  
from any possible source of flammable fumes or  
4. Confirm that the cable you have just installed is  
properly connected. Specifically, make certain that  
the cable is connected to the Negative (-) terminals on  
both the inverter and the 12 volt power source.

gases.  
Failure to heed this warning could result in fire or  
explosion.  
6. For safe and proper operation of the inverter when  
not using the supplied cables, connect the inverter  
to the power source with the proper gauge wire  
available and in the shortest length practical. When  
the inverter and the battery are set up within four feet of  
each other, use a minimum of #8 gauge wire to make  
the connections. Within four to six feet, use #6 gauge  
wire. At distances between six feet to ten feet, use #4  
gauge wires connected to the battery.

OPERATION  
OPERATION  
7. Run a ground from the Ground Lug Terminal at the  
rear of the inverter to a proper grounding point using  
the shortest practical length of 18 AWG wire.  
Selection of the grounding point will depend on  
where you are using the inverter. The ground wire may  
be connected to the chassis of your vehicle or to the  
grounding system in your boat or to the earth* if you  
are operating the inverter in a remote location. Before  
connecting to the ground, make certain that the  
inverter is turned off.  
Note:  
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 disconnected from the 12 volt power source.  
The use of an extension cord from the inverter to the  
appliance or equipment being operated will decrease  
the power being delivered to the load. 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 damage  
the inverter, the power source, or may generate  
excessive heat.  
Operating the inverter without properly grounding it  
may result in electric shock.  
* This ground can’t be the same ground as the AC  
ground.  
8. Confirm that the equipment or appliance to be operated  
is turned off. Plug the equipment or appliance into one of  
the AC receptacles on the front panel of the inverter.  
9. Turn the inverter to the ON (I) position. Turn on the  
equipment or appliance.  
10. Plug the USB powered device into the inverters USB  
power port.

OPERATION  
OPERATION  
Important Information on Battery Chargers  
The Power Source.  
When the engine is off, most batteries will provide ample  
power 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.  
Using your inverter with battery chargers for 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  
modified sine wave inverters if you’re unsure.  
Although we advise against it, if you attempt to use 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.  
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.  
Don’t Blow A Fuse.  
Although it is not necessary to disconnect the inverter  
when turning over the engine, the inverter may  
momentarily cease operation as the battery voltage  
decreases. When the inverter is not supplying power, and  
is turned on, it draws very low (<0.80 A).  
This inverter is equipped with internal spade type fuses.  
With reasonable care, it should not be necessary to  
replace the fuse(s) in your inverter.  
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 electronic  
knowledgeable people should attempt fuse replacement.  
Note:  
Make certain to correct the source of the overload  
which caused the blown fuse before turning your  
inverter back ON (l).

following problems occur:  
For You Television Fans and Audiophiles.  
Although the inverter is shielded and filtered to minimize  
signal interference, some interference with your television  
picture may be unavoidable, especially with weak signals.  
However, here are some suggestions that may improve  
the reception.  
1. First, make certain that the television antenna pro  
duces a clear signal under normal operation  
conditions (i.e., at home plugged into a standard  
110AC wall outlet). Also, ensure that the antenna  
cable is properly shielded and of good quality  
2. Change the relative positions of the inverter, antenna  
cables and television power cord.  
1. The power input from the battery drops below  
10 volts.  
2. The power input from the battery exceeds 15.5+/-0.5  
volts.  
3. The continuous draw of the appliance or equipment  
being operated exceeds the design parameters of the  
inverter.  
The inverter is equipped with the following additional safety  
features:  
1. Thermal Cut Off  
Automatic shut down if internal temperature exceeds safe  
design parameters.  
3. Isolate the television, its power cord and antenna  
cables and television power cord.  
4. Coil the television power cord and the input cables  
running from the 12 volt power source to the inverter.  
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.  
b) The inverter will automatically shut down when the  
input voltage drops below 10 volts. This protects the  
battery from completely draining.

CARE AND MAINTENANCE  
CARE AND MAINTENANCE  
VENTILATION. In order to disperse the heat generated  
while the inverter is in operation, keep it well  
ventilated. While in use, maintain several inches of  
clearance around the top and sides of the inverter.  
Note: Inexpensive sound systems may emit a  
“buzzing” sound when operated with the inverter.  
This is due to inadequate filters in the sound system.  
There is no solution to this problem short of purchasing a  
sound system with a higher quality power supply.  
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.  
Some Powerful Advice.  
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.  
To maintain your inverter in proper working condition, note  
the following important safety precautions:  
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 surfaces 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.  
HEAT. For peak efficiency, the ambient air temperature  
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.

OPERATING PRINCIPLES  
OPERATING PRINCIPLES  
For You Technical Types.  
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."  
1. Basic Operating Principles:  
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.  
A true sine wave typical of home AC outlet.  
The modified sine wave produced by the inverter  
The modified sine wave produced by your Whistler inverter  
has a root mean square (RMS) voltage of 110 volts. The  
majority of AC voltmeters measure RMS voltage and assume  
that the measured waveform will be a pure sine wave.

In Review.  
When operating the inverter with the engine off, start the  
engine every hour and let it run for at least 10 minutes to  
recharge the battery.  
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.  
In the event of automatic shut down, turn the inverter OFF  
(O) immediately. Do not restart the inverter until the  
source of the problem has been identified and corrected.  
This inverter is designed to be connected to the power  
source with the supplied cables or larger cables that  
properly match the distance from the battery. When  
utilizing the supplied cables, do not attempt to modify  
or lengthen them.  
To avoid battery drain, always disconnect the inverter  
when not in use.  
Always make certain that the power cable terminal  
connections Negative (-) to Negative (-) and Positive (+)  
to Positive (+). Check these connections frequently to  
ensure that they are secure.  
Do not expose the inverter to moisture.  
Avoid placing the inverter near sources of heat or in  
direct sunlight.  
When in use, make certain that the inverter is properly  
ventilated.  
Make certain the rated power consumption of the  
appliance or equipment you wish to operate is  
compatible with the capacity of your inverter.  
Do not use the inverter near flammable materials,  
fumes, or gases.  
If the rated power consumption of the equipment is in the  
range of the maximum specified wattage of your  
converter, test the inverter to ensure that it will operate  
properly.
