A Word About WHISTLER GO AC™ Inverters.  
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.  
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."  
This manual will provide you with directions for the safe  
and efficient operation of your WHISTLER GO AC 150  
Watt or 350 Watt Inverter. Read the manual carefully  
before using your new WHISTLER Inverter and keep the  
manual on file for future reference.  
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 invert-  
er 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.  
Do not attempt to connect the PP150AC Inverter  
directly to the 12 volt power source other than using  
the supplied adapter cord and plug or the optional  
WHISTLER 12 volt hard wire adapter kit (Part Number  
PP010DC).  
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 owners 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 modify the adapter cords, plugs or  
any of the elements that comprise the PP350AC hard  
wire adapter kit.  
110 volts of current can be lethal. Improper use of  
yo ur WHISTLER inverter may result in property  
damage, personal injury or loss of life.  
Check with the appliance manufacturer for compati-  
bility with modified sinewave inverters. So me  
appliances may not work well or not at all. This is espe-  
cially true for medical equipment. For more information  
on compatibility issues, please visit our inverter FAQ page  
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. As a general rule, you can determine the  
required start up load by multiplying the wattage rating by 10.  
For further information on the fundamental operating prin-  
ciples of WHISTLER inverters and related technical data,  
see "Technical Operating Principles"

INVERTER BASICS  
INVERTER BASICS  
Dont 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 GO AC inverter has the capacity  
to provide power output (excess current) equal to approxi-  
mately 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 150 model has a maximum continuous rat-  
ing of 150 watts. Although this model has the capacity to  
briefly provide up to 300 watts of power (that is, excess cur-  
rent), it is designed to operate equipment and appliances  
with start up load requirements of 150 watts or less.  
Note:  
Most heat generating appliances require start up loads  
in excess of 1000 watts and the WHISTLER 150 and 350  
inverters 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.  
To connect the PP350AC using the Hard Wire Adapter  
Kit (P/N PP010DC), follow these steps:  
1. Push the adapter plug leading from the inverter firm-  
ly into the Hard Wire Adapter Kit socket.  
2. Properly identify the positive and negative terminals  
on the 12 volt power source and make certain that the  
terminals are clean and dry.  
3. Connect the RED alligator clip to the Positive (+) ter-  
minal on the power source and the BLACK alligator  
clip to the Negative (-) terminal on the power source.  
4. Plug your equipment or appliance into the AC recep-  
tacle on the inverter.  
The PP150AC is designed to connect to your 12 volt battery  
through the cigarette lighter socket on your dashboard.  
(See the following section for instructions for connecting the  
PP350AC).  
To connect the 150 inverter, follow these steps:  
1. Remove the cigarette lighter and push the adapter  
plug firmly into the cigarette lighter socket. (Make  
certain both the socket and adapter plugs are clean).  
2. Plug your appliance or equipment into the AC  
receptacle on the inverter.  
3. Turn the inverter rocker switch to the ON (l) position.  
4. Confirm that the LED Power Indicator light on the  
inverter is glowing GREEN. This GREEN light indi-  
cates that your WHISTLER inverter is "ready for  
action."  
5. Turn the inverters rocker switch to the ON (l) position.  
6. Confirm that the LED Power Indicator light on the  
inverter is glowing GREEN. This GREEN light indi-  
cates that the inverter is "ready for action."  
5. Turn on your appliance or power equipment.  
7. Turn on the equipment or appliance.  
The PP350AC is designed to connect to your 12 volt battery  
either through the cigarette lighter socket or directly to the  
battery using the supplied Hard Wire Adapter Kit.  
To connect the PP350AC with the cigarette lighter adapter  
plug and cord, follow the steps as outlined above.  
Note:  
If the equipment or appliance you intend to operate,  
requires more than 150 watts of continuous power, the  
PP350AC should be connected directly to the power  
source using the Hard Wire Adapter Kit. Failure to  
do so may result in serious damage to the power cord  
or to the cigarette lighter socket wiring.

OPERATION  
OPERATION  
Note:  
Important Information on Battery Chargers  
It is normal for the PP150AC and PP350AC audible  
alarm to make a momentary "chirp" when you plug  
the adapter into the cigarette lighter socket or when  
you turn on the appliance or equipment. However, if  
the alarm sounds for an extended period, turn the  
appliance or equipment off immediately. This alarm  
indicates that the input from the battery has dropped  
below 10.5 volts. Do not attempt to operate the  
inverter until the battery has been recharged.  
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.  
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.  
(For further information on this audible alarm feature,  
see "Automatic Shut Down Safety Features.")  
Dont Blow A Fuse.  
The WHISTLER 150 is equipped with a 20 amp spade type  
fuse;the WHISTLER 350 with a 35 amp, spade type fuse. With  
reasonable care, it should not be necessary to replace the  
fuse in your inverter.  
The use of an extension cord from the inverter to the  
appliance or equipment being operated will not  
significantly decrease the power being generated by  
the inverter. For best operating results, the extension  
cord should be no more than 50 feet long.  
Most blown fuses are the result of reverse polarity or a short  
circuit within the appliance or equipment being operated. If  
the fuse does blow, turn off and disconnect the appliance  
or equipment from the inverter immediately, repair the  
related problem and replace the fuse in accordance with  
the following instructions: The fuse compartment is easily  
accessed at the back of the unit underneath the "lift up"  
cover.  
Check frequently to ensure that the input and output  
connections are secure. Loose connections may cause  
damage to the inverter or battery or may generate  
excessive heat.

OPERATION  
OPERATION  
Although it is not necessary to unplug the inverter when turn-  
ing over the engine, the inverter may momentarily cease  
operation as the battery voltage decreases. When the invert-  
er is not supplying power, it draws very low amperage from  
the battery (<0.10 A to <0.20 A depending on the model) and  
may be left connected to the battery for up to three hours.  
However, we recommend the inverter always be disconnect-  
ed when not in use.  
Note:  
All WHISTLER inverters are shipped with a replace-  
ment fuse. Do not install a fuse with a higher rating  
than that specified. Doing so may damage the inveter.  
This same precaution also applies when the vehicles  
cigarette lighter fuse is blown. Always replace the cig -  
arette lighter fuse with a fuse of the same type and rat-  
ing as indicated in the vehicles owners manual.  
Note:  
Inverters will not operate with certain automotive sys-  
tems unless the ignition is on. If the inverter is not  
generating power, try turning the ignition to the  
accessory position.  
Make certain to correct the source of the overload  
which caused the blown fuse before turning your  
inverter back ON (l).  
The Power Source.  
When the engine is off, most batteries will provide an 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.  
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 recom-  
mend that the device plugged into the inverter be turned off  
before turning over the engine.

b) The inverter will automatically shut down when the  
input voltage drops below 9.5 volts. This protects the  
battery from completely draining.  
Automatic Shut Down & Related Safety Features.  
Each WHISTLER GO AC 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:  
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.  
GREEN LED:  
System ready.  
YELLOW LED: System overload/automatic shut down.  
Note:  
The Whistler PP350AC model only is equipped with a  
cooling fan which is designed to run continuously  
while the inverter is operating. Automatic shutdown  
caused by excess circuit temperature occurs when the  
cooling fan is unable to maintain the design parameters  
for safe operation of the inverter.  
Your inverter will shut down automatically when any of the  
following problems occur:  
1. The power input from the battery drops below  
9.5 volts.  
2. The power input from the battery exceeds 16 volts.  
Wall Mounting :  
3. The continuous draw of the appliance or equipment  
being operated exceeds the design parameters of the  
inverter.  
Whistler inverters have provisions for wall mounting; two  
slotted holes in the handle area and a notched area at the  
power cord end allow for easy wall mounting of the unit.  
The WHISTLER PP150AC and PP350AC models are equipped  
with the following additional safety features:  
Some Powerful Advice.  
1. Thermal Cut Off:  
Your WHISTLER GO AC inverter will work best when placed  
on a reasonably flat surface. The floor or seat of your car or  
truck both are good locations.  
Automatic shut down when the internal circuit temperature  
exceeds standard design parameters for safe opera-  
tion.  
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.

CARE AND MAINTENANCE  
CARE AND MAINTENANCE  
(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).  
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.  
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.  
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.  
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 assume that the measured waveform will be a pure sine  
wave.  
1. Basic Operating Principles:  
WHISTLER GO AC 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 con-  
verted to 110 volts (60 Hz AC) using advanced power MOS-  
FET transistors in a full bridge configuration. The result is  
excellent overload capability and the capacity to operate dif-  
ficult reactive loads. The output waveform resulting from  
these conversions is a "quasi-sine wave" or a "modified sine  
wave" as shown on the following page.  
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."  
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 GO AC Inverter  
A true sine wave typical of home AC outlet.

OPERATION SUMMARY  
In Review.  
Use only fuses which conform with the design specifica-  
tions outlined in this manual.  
Never attempt to operate your WHISTLER inverter from  
any power source other than a 12 volt battery.  
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.  
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.  
The WHISTLER 150 is designed for use only with the cig-  
arette lighter socket adapter plug or the optional  
WHISTLER 12 volt hard wire adapter kit (part number  
PP010DC).  
The WHISTLER 350 is designed for use with the cigarette  
lighter socket adapter plug or with the Hard Wire  
Adapter Kit. When operating the WHISTLER 350 with  
equipment or appliances requiring in excess of 150 watts  
of continuous load, use the Hard Wire Adapter Kit.  
To avoid battery drain always disconnect the inverter  
when not in use.  
Do not expose the inverter to moisture.  
Avoid placing the inverter near sources of hear or in  
direct sunlight.  
Make certain the rated power consumption of the appli-  
ance or equipment you wish to operate is compatible with  
the capacity of your inverter.  
When in use, make certain that the inverter is properly  
ventilated.  
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.  
Do not use the inverter near flammable materials, fumes  
or gases.  
WHISTLER 150 and 350 Watt Inverters are not designed to  
operate heat generating appliances such as coffee makers,  
irons, hair dryers, toasters and heaters.
