A Word About WHISTLER Inverters.
WHISTLER manufactures a complete line of DC to AC inverters ranging
in capacity from 50 Watts to 2500 Watts. These inverters offer advanced
technology, dependable operation and will provide years of reliable
service when used in accordance with our operating instructions.
WHISTLER inverters convert low voltage, direct (DC) current to 110 volt alternating (AC) household current 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.
Certain models in the WHISTLER inverter line operate indirectly through
an adapter which plugs into the cigarette lighter socket in your car, truck
or boat. Other models, such as the WHISTLER 500, are designed to be
hard wired directly to the 12 volt power source.
Important Information About The WHISTLER 500 Watt Inverter.
This manual will provide you with directions for the safe and efficient operation ofyour WHISTLER 500 Watt Inverter. Read the manual carefully before
using your inverter and keep the manual on file for future reference.
• The WHISTLER 500 is designed to operate from a 12 volt power
source only. Never attempt to connect the inverter to any other
power source including any AC power source.
• Do not attempt to extend or otherwise modify the connector cables.
• 110 Volts of current can be lethal. Improper use of your inverter may
result in property damage, personal injury or loss of life.
Getting Off To A Good Start
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,
devices such as standard light bulbs do not require a 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.”
In order to ensure that the capacity of your WHISTLER 500 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.
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 owner’s manual or
contact the manufacturer.
If the power consumption is rated in amps, multiply the number of amps
by 110 (AC voltage) to determine the comparable 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 principles of
inverters and related data, see the section in this manual entitled “For
You Technical Types.”
Don’t Push It.
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 500 model has a maximum continuous rating of 500
watts. Although this model has the capacity to briefly provide up to 800
watts of power (that is, excess current), it is designed to operate equipment and appliances with start up load requirements of 500 watts or less.
Consequently, if the start up load rating of your equipment or appliance
is in the 500 watt range, the WHISTLER 500 may not have the capacity
to provide the required start up load.
To determine whether the WHISTLER 500 will operate a particular piece of
equipment or appliance, run a test. The WHISTLER 500 is designed to
automatically shut down in the event of a power overload and testing appliances and equipment with ratings in the 500 watt range will not damage it.
If a piece of equipment or an appliance in the 500 watt range will not
operate properly when first connected to the inverter, turn the inverter
rocker switch ON (I), OFF (0), and ON (I) again in quick succession. If this
procedure is unsuccessful, it is likely that the WHISTLER 500 does not have
the required capacity to operate the equipment or appliance in question.
• Most heat generating appliances require start up loads in excess of
1000 Watts and the WHISTLER 500 will not operate such appliances
as coffee makers, irons, hair dryers or heaters.

Making The Connection.
1. Make certain that the WHISTLER 500 rocker switch is in the OFF (0)
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
over 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.
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 vo/t power source.
5. Connect the cable from the (RED) Positive (+) terminal on the inverter to the Positive terminal on the power source. Make certain
the connection is secure.
• Loose connections can result in a severe decrease in voltage which
may cause damage to the wires and insulation.
• Failure to make a 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 charge 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.
• If the supplied cables are too short to allow for placement of the
inverter in a desired location, the inverter may be connected to the
power source using a #4 wire. 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 confirming that there is power
running to the inverter.
7. Turn the inverter rocker switch to the OFF (0) 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 operated is turned
off. Plug the equipment or appliance into one of the two AC receptacles on the front panel of the inverter.
9. Turn the inverter to the ON (I) position. Turn on the equipment or
• As indicated in Step 7 above, the audible alarm may make a momentary “chirp” when the inverter is turned OFF (0). This same alarm
may also sound when the inverter is being connected to or disconnected from the 12 volt power source. Again, this is normal.
• 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.
• Check frequently to ensure that the input and output connections
are secure. Loose connections may damage the inverter or the
power source or may generate excessive heat.
You’ll Get A Charge Out Of This. (Or Maybe Not).
Using the WHISTLER 500 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 to 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 You Television Fans & Audiophiles.
Although the WHISTLER 500 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 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.
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.
4. Coil the television power cord and the input cables running from the
12 volt power source to the inverter.
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. See Radio
Shack Part # 273-105).
6. Ground the WHISTLER 500 using an 8 AWG grounding wire in as
short a length as possible.
• Before connecting the ground, make certain that the inverter rocker
switch is OFF (0).
• Run the ground wire from the Grounding Terminal on the rear panel
of the inverter. (See “Rear View” Illustration, Page 3).
• The selection of a proper grounding point will depend on where you
are using the inverter. The grounding terminal 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.
• Inexpensive sound systems may emit a “buzzing” sound when operated with the WHISTLER 500. 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.
Don’t Blow A Fuse.
Your WHISTLER 500 is equipped with two 35 amp, spade type fuses.
With reasonable care, it should not be necessary to replace these fuses.
Most blown fuses are the result of reverse polarity or a short circuit
within the appliance or equipment being operated. If the fuses do blow,
disconnect the appliance or equipment immediately, repair the related
problem and install the new fuses which have been supplied with your
The fuse compartments are easily accessed at the back of the unit
underneath the “lift up” covers. (See “Rear View” Illustration, Page 3).
• Do not install a fuse with a rating higher than 35 amps. Doing so
may damage the inverter.
• Make certain to correct the source of the overload which caused the
blown fuse before turning the WHISTLER 500 back ON (I).
The Power Source.
When the engine is off, most automobile and marine batteries will
provide an ample power supply to the inverter for 30 to 60 minutes.
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 approximately 10 minutes
to recharge the battery. We also recommend that the device plugged
into the inverter be turned off before turning over the engine.
Although it is not necessary to disconnect the WHISTLER 500 when
turning over the engine, the inverter may momentarily cease operation
as the battery voltage decreases. When the WHISTLER 500 is not
supplying power, it draws very low amperage (< 0.6 A) from the battery
and may be left connected to the battery for up to three hours. However, we recommend the inverter always be disconnected when not in
Automatic Shut Down Safety Features.
The LED Indicator light (See “Front View” Illustration, Page 3) will turn
from GREEN to RED and the WHISTLER 500 will turn itself off automatically when:
1. The power input from the battery drops to 10.5 volts. (When the power
input drops to 11 volts, an alarm will sound for an extended period);
2. The power output from the battery exceeds 15 volts;
3. The continuous draw of the equipment or appliance being operated
exceeds 500 watts.
4. The circuit temperature exceeds standard design parameters for safe
• The WHISTLER 500 is equipped with a cooling fan which is designed
to run continuously while the inverter is operating. Automatic shut
down caused by excess circuit temperatures occurs when the cooling
fan is unable to maintain the design parameters for safe operation of
the inverter.
• In the event of automatic shut down or continuous audible alarm,
turn the inverter rocker switch to the OFF (0) position until the
source of the related problem has been determined and resolved.
Some Powerful Advice.
Your WHISTLER 500 will work best when placed on a reasonably flat
surface. The floor or your car or truck is a good location as long as the
area is dry and well ventilated.
(When driving with the WHISTLER 500 in operation, make certain that
neither the inverter nor the power cables will impede safe operation of
your vehicle. Keep the inverter and all cables and cords clear of the
steering wheel, gear shift and gas, brake and clutch pedals).
To maintain your WHISTLER 500 in proper working condition, note the
following important safety precautions:
• MOISTURE. Keep the WHISTLER 500 dry. Do not expose it to moisture.
Do not operate the WHISTLER 500 ifyou, the inverter the device
being operated or any other surfaces that may come in contact with
any power source are wet. Water and many other liquids can ~conduct electricity which may lead to serious injury or death.
• HEAT. The ambient air temperature should be between 500 and 800
F. Avoid placing the inverter on or near heating vents, radiators or
other sources of heat. Do not place the inverter in direct sunlight.
VENTILATION. In order to properly disperse 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
• 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.
For You Technical Types.
I. Basic Operating Principles.
The WHISTLER 500 works 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.
This stepped waveform is similar to the power generated by utilities
and has a broad range of applications.
145 vOlts pesk
115 volts AMS
WHISTLER PP500AC Inverter Modified Sine Wave
The modified sine wave produced by the WHISTLER 500 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.
Consequently, these meters will not read the RMS modified sine
wave voltage correctly and, when measuring the WHISTLER 500
output, the meters will read about 20 to 30 volts too low. To accurately measure the output voltage of the WHISTLER 500, use a true
RMS reading voltmeter such as a Fluke 87, Fluke 8060A, Beckman
4410, Triplett 4200 or any multimeter identified as “True RMS.”
In Review.
• Never attempt to operate the WHISTLER 500 from any power source
other than a 12 volt battery.
• The WHISTLER 500 is designed to be connected to the power source
with the supplied cables or with #4 wire. When utilizing the cables,
do not attempt to modify them.
• 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.
• While connecting the WHISTLER 500 to the power source, make
certain the inverter is well removed from any potential source of
flammable fumes or gases.
• Make certain the power consumption of the appliance or equipment
you wish to operate is compatible with the capacity of the inverter.
• If the rated power consumption of the equipment is in the 500 Watt
range, test the inverter to ensure that it will operate properly.
• The WHISTLER 500 is not designed to operate heat generating appliances such as coffee makers, irons, hair dryers, toaster and heaters.
• When attempting to recharge battery chargers, monitor the temperature of the charger for approximately 10 minutes. Ifthe charger becomes abnormally warm, disconnect it from the inverter immediately.
• Use only 35 amp, spade type fuses with the WHISTLER 500.
• When operating the inverter with the engine off, start the engine
every 30 to 60 minutes and let it run for approximately 10 minutes to
recharge the battery.
• In the event a continuous audible alarm or automatic shut off (Green
LED Indicator light turns Red), turn the inverter OFF (0) immediately.
Do not restart the inverter until the source of the problem has been
identified and corrected.
• Always disconnect the inverter when not in use.
• 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.
• Do not use the inverter near flammable materials, fumes or gases.
