A Word About Whistler Power Inverters  
Topic  
Page  
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.

Fan also will automatically turn on. Overheating may result  
when the inverter is being operated at levels exceeding  
its wattage rating or because it has been placed inalocation  
or in an manner which prevents proper heat dissipation.  
After approximately 15 minutes, the High Temperature  
Indicator light and the Cooling Fan will turn off and the  
inverter will automatically restart indicating that the inverter  
temperature has dropped to a safe operating level.  
d). Wattage & Voltage  
Wattage Indicator. This illuminated Digital display moni-  
tors the wattage being consumed by the inverter.  
When the reading rises above the rated limits, the inverter  
may automatically shut down. In this event, it is likely that  
the draw of the equipment or appliance being operated is  
greater than the battery is capable of producing.  
Voltage Indicator. This Digital display monitors the voltage  
being drawn from the battery by the inverter. The voltage  
is measured at the Negative and Positive power input terminals  
on the inverter. The voltage level reading will be lower  
than the battery voltage due to the voltage "drop" that  
occurs as the battery voltage runs through the terminal  
connections and cables.  
Over Load LED Indicator Light. This light will turn RED and the  
inverter will automatically shut down when the continuous  
power draw from the inverter exceeds the maximum  
continuous power rating for the inverter. Turn the inverter  
OFF (O), determine and resolve the cause of the overload  
prior to resuming operation of the equipment or appliance.  
Turning the inverter ON (I) will reset it.  
The inverter is designed to operate with input voltages  
ranging from 10 to 15 volts. When the voltage drops below  
10.5 volts DC an audible alarm will sound. If the voltage  
drops below 10 volts DC, the voltage indicator will go out  
and the inverter will automatically shut down. The inverter  
also will shut down automatically when the input voltage  
exceeds 15 volts DC. Despite this "built in" protection,  
the inverter may be damaged if the input voltage exceeds  
15 volts DC and damage caused by excess voltage input  
is not covered under the WHISTLER warranty.  
c).Remote Operation Jack.  
The inverter is designed to be operated from a remote  
location via the WHISTLER PP015DC Remote Control  
Switch which plugs into this socket. This optional accessory  
is available through WHISTLER or your WHISTLER dealer.

IMPORTANT INFORMATION  
INVERTER INFORMATION  
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."  
Important Information About Your New Whistler Inverter.  
This manual will provide you with directions for the safe  
and efficient operation of your Whistle Power Inverter.  
Important Note: Each of the following operating procedures  
and safety features must be carefully reviewed and thor-  
oughly understood prior to using the inverter. Failure to  
do so may result in damage to the inverter or equipment  
or serious personal injury.  
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.  
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.  
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 appliance  
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, computer,  
etc.) is compatible with a modified sine wave.  
110 volts can be lethal. Improper use of your Whistler  
inverter may result in property damage, personal  
injury or loss of life.  
NOTE: Not recommended for use with medical equip-  
ment.  
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 may require 2 to 6 times  
their wattage rating to start up.  
Check with the appliance manufacturer for  
compatibility with modified sine wave inverters.  
Some appliances may not work well, not at all or be  
damaged. This is especially true for medical equipment.  
For more information on compatibility issues, please visit  
our inverter FAQ page at:

Don’t Push It.  
start up load ratings comparable to your inverter wattage  
rating will not damage it.  
Although your Whistler power 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.  
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 or  
your battery supply isn’t large enough to operate the  
equipment or appliance in question.  
For example, the 1200 model has a maximum continuous  
rating of 1200 watts. Although this model has the capacity  
to briefly provide up to 2400 watts of power (that is, excess  
current), it is designed to operate equipment and appliances  
with start up load requirements of 1200 watts or less.  
Selecting the Optimum Power Source.  
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.  
Operating the inverter for extended periods combined with  
a high continuous load demand may result in excessive  
power drain from the battery. Therefore, the reserve capacity  
of the battery you select to power the inverter is an  
important consideration.  
Some refrigerators, freezers, pumps and other similar  
equipment and appliances require very high start up loads  
to operate. Before attempting to power up this type of  
equipment or appliance, make especially certain that all  
connections have been properly made and that the power  
source is fully charged.  
The potential power drain can be estimated by calculating  
the reserve power ("amp/hour") of the battery and the  
amps required by the inverter to meet the continuous load  
demand of the equipment or appliance being operated.  
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

BATTERY/CABLE INFORMATION  
BATTERY INFORMATION  
1. To calculate the amp/hour of the battery, first determine  
its "reserve minutes" rating. (Deep cycle marine batteries  
generally have the highest reserve minute ratings). This  
rating typically is marked on the battery along with the  
"Cold Cranking Amps" (CCA) rating. Multiply the reserve  
minutes rating of the battery by 0.3 to determine the  
battery amp/hour rating. A battery with a reserve minutes  
rating of 166 has an amp/hour.  
It may be advisable to operate the inverter from a bank  
of batteries of the same type in a "parallel" configuration.  
Two such batteries will generate twice the amp/hours  
of a single battery; three batteries will generate three  
times the amp/hours and so on.  
This multiple parallel battery option is especially  
recommended for the Whistler 3000 inverter due to the  
high level of amps these models require to produce up  
to 3000 watts of continuous load. For more information  
regarding battery power please visit our inverter faq  
2. To estimate the maximum battery power the inverter  
will require to run a piece of equipment or appliance,  
divide its continuous load wattage requirement by 10.  
The WHISTLER 1200 watt model utilizes 50 amps of battery  
power to operate an appliance with a 500 watt continuous  
load requirement. (500 divided by 10 = 50).  
Wire Cable Gauges  
For safe and proper operation of the inverter, connect the  
inverter to the power source with the thickest wire available  
and in the shortest length practical.  
3. Conclusion: The reserve power of the battery is sufficient  
to satisfy the continuous load demand placed on the  
inverter for a maximum of about one hour. (49.8 divided  
by 50 = 1 hour).  
1200  
When the inverter and the battery are set up within four feet  
of each other, use a minimum of #4 gauge wire to make the  
connections. Within four to six feet, use a minimum of #2 gauge  
wire. At distances of more than six feet, use #0 gauge wire.  
Note:  
When the inverter will be operating equipment or  
appliances with high continuous load ratings for extended  
periods, it is not advisable to power the inverter with the  
same battery used to power your vehicle. If the car or truck  
battery is utilized for an extended period, it is possible that  
the battery voltage may be drained to the point where  
the battery has insufficient reserve power to start the vehicles.  
Regardless of the wire gauge selected to make the connections  
to the battery, we recommend use of an "O Ring

Adapter." Use of #0 gauge wire to make the connections to  
the inverter may require a "0 to 4 Gauge Adapter." Both  
adapters are available through electronic supply stores  
including Radio Shack. Radio Shack part number is listed below:  
1. Make certain that the Power 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.

(To make these connections on the 2000 and 3000,  
remove the supplied nut at each terminal on the inverter,  
install the wire connectors flush with the metal backing  
plates and refasten the nuts securely.  
2000 and 3000  
When the inverter and the battery are set up within four  
feet  
of each other, use a minimum of #2 gauge wire to make the  
connections. Within four to six feet, use two #0 gauge wire.  
At distances of more than six feet, use #0 gauge wires  
connected in parallel to the battery.  
3. Connect the cable from the Negative (-) terminal on  
the inverter to the Negative (-) terminal on the 12 volt  
power source. Make certain the connection is secure.  
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.  
5. Connect the cable from the Positive (+) terminal on  
the inverter to the Positive (+) terminal on the power  
source.

OPERATION  
OPERATION  
Note:  
7. Turn the inverter ON (I). Check the Meter on the  
front panel. The Voltage should read between 11  
and 14 volts depending on the voltage of the power  
source. If the reading is not within this range, check  
the voltage of the power source and the terminal  
connections on the power source and the inverter  
to make sure they are secure.  
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 sparking, however,  
it is extremely important that both the inverter and the  
12 volt battery be well removed from any possible  
source of flammable fumes or gases.Failure to heed  
this warning could result in fire or explosion.  
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 the inverter.  
9. Turn the inverter to the ON (I) position. Turn on the  
equipment or appliance.  
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.  
Again, this is normal.  
6. 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  
the ground, make certain that the inverter is turned off.  
Operating the inverter without properly grounding it  
may result in electrical shock.  
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.  
* This ground can’t be the same ground as the AC ground.

or the charging unit. Check with the appliance manufacturer  
for compatibility with sine wave inverters if you’re unsure.  
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.  
The following precautions apply to the 3000 watt  
models only.  
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.  
a). The AC receptacles are equipped with 15 amp circuit  
breakers. Consequently, each of these outlets is rated  
for a maximum output of 1500 watts (110 volts x 15 amps).  
The Power Source.  
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, the number of batteries 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 30 to 60  
minutes 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.  
To generate the maximum output, the 3000 watt model  
should be connected to a power supply which has the  
capacity to produce up to 300 amps. The loads should  
be distributed between the two receptacles to ensure  
that each outlet is producing no more than its maximum  
1500 watt output.  
If more than one piece of equipment or appliance is  
to be operated at the same time, first turn on the  
inverter and then turn on each piece of equipment or  
appliance separately to enable the inverter to produce  
the required start up loads.  
Although it is not necessary to turn off 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 turned on, it draws low amperage from  
the battery (<0.65 A ).

may be unavoidable, especially with weak signals. However,  
here are some suggestions that may improve the reception.  
For You Microwave Chefs.  
1. First, make certain that the television antenna produces  
a clear signal under normal operating conditions (i.e.,  
at home plugged into a standard 110 AC wall outlet).  
Also, ensure that the antenna cable is properly shielded  
and of good quality.  
The power rating commonly associated with microwave ovens  
is the "cooking power" which is the power being "delivered"  
to the item being microwaved. The actual operating power  
requirement rating is higher than the cooking power rating  
and typically is referenced on the back of the microwave. If  
the operating power requirement does not appear on the  
back of the microwave, check the owners manual or contact  
the manufacturer.  
2. Change the relative positions of the inverter, antenna  
cables and television power cord.  
3. Isolate the television, its power cord and antenna cables  
from the 12 volt power source by running an extension  
cord from the inverter to the television set.  
Some Powerful Advice.  
Your Whistler inverter will work best when placed on a reasonably  
flat surface. The floor or wall of your vehicle are good locations.  
4. Coil the television power cord and the input cables running  
from the 12 volt power source to the inverter.  
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.  
5. Attach a "Ferrite Data Line Filter" to the television power  
cord. More than one filter may be required. These filters  
are available at most electronic supply stores including  
Radio Shack. (Radio Shack Part Number is 273-105).  
Note:  
To maintain your inverter in proper working condition, note  
the following important safety precautions:  
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 his

The modified sine wave produced by  
your Whistler 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 are calibrated for RMS voltage and assume  
that the measured waveform will be a pure sine wave.  
For You Technical Types.  
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  
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."  
For more information on inverters see our Inverter FAQ page  
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.  
Before attempting to use a battery charger see page 19.  
Before attempting to use medical equipment see page 8.  
Use the heaviest gauge wire (smaller the number, the  
larger or heavier the cable) available to connect the  
inverter to the power source.  
When operating the inverter with the engine off, start the  
engine every 30 to 60 minutes and let it run for at least  
10 minutes to recharge the battery.

In Review.  
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.  
Never attempt to operate your Whistler inverter from  
any power source other than a 12 volt battery or a  
group of batteries that total 12 volts.  
To avoid battery drain always disconnect the inverter  
when the vehicle is not in use for long periods.  
Always make certain that the power cable terminal  
connections run Negative (-) to Negative (-) and  
Positive (+) to Positive (+). Check these connections  
frequently to ensure that they are secure.  
Do not expose the inverter to moisture.
