A Word About Whistler Power 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 automo-
bile and marine batteries or from portable high power 12
volt sources.
Inverter Features
a). ON/OFF Switch.This switch controls the flow of power
from the power source to the inverter. It does not control
the power running from the inverter to the equipment or
appliance being operated.
b). High Temperature LED Indicator Light. This light will
turn RED and the inverter will automatically shut down
when the internal temperature exceeds design parameters

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 Bar Graph displays the voltage
being drawn from the battery by the inverter. The voltage is
measured at the Negative and Positive power input termi-
nals 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 con-
nections and cables.
The inverter is designed to operate with input voltages
ranging from 10 to 15 volts. When the voltage drops below
10.5 volts DC, the voltage indicator will register in the lower
RED zone and 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 volt-
age exceeds 15 volts DC and damage caused by excess
voltage input is not covered under the WHISTLER warranty.
Under optimum conditions, the voltage reading will be in
the GREEN zone.
Note:
In the event of automatic shut down or continuous audible
alarm, turn the inverter OFF (O) until the source of the relat-
ed problem has been determined and resolved.

FEATURES
for safe operation. When this occurs, turn the equipment
or appliance off.
In the event of excess temperature, the High Speed
Cooling 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 in a location or in an manner which prevents prop-
er 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 oper-
ating level.
c). 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 equip-
ment or appliance. Turning the inverter ON (I) will reset it.
d). Battery Current & Voltage Bar Graph Meters
(GREEN, YELLOW, RED).
Current Indicator.This illuminated Bar Graph monitors
the current being drawn from the battery by the inverter.
Depending on the amount of current being drawn, the Bar
Graph reading generally will be in the GREEN or YELLOW

INVERTER INFORMATION
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 thoroughly understood prior to using the inverter.
Failure to do so may result in damage to the inverter or
equipment or serious personal injury.
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.
•110 volts can be lethal. Improper use of your
Whistler inverter may result in property
damage, personal injury or loss of life.
•Check with the appliance manufacturer for com-
patibility with modified sine wave inverters. Some
appliances may not work well, not at all or be dam-
aged. This is especially true for medical equipment.

IMPORTANT INFORMATION

Getting Started
Powerequipmentandappliances which operatewithmotors
or tubes requirean initial surge of power to get themup 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 hasbeen powered
up,it settles downtoaslowerpaceandrequiresfar lesselec-
trical power to operate. This lower power requirement is
referred to as the "continuous load."
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.
Power consumption isratedeither 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 isnot 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.
If the power consumption is rated in amps, multiply the
number ofamps by110 (AC voltage) to determine the com-
parable wattage rating. As a general rule, you can deter-
mine 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"
1250/1750/2750 Manual 3/6/02 2:45 PM Page 11

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
ratingwill not damage it.
If apiece ofequipment oran appliance will notoperate,first
confirm that the inverter has been properly connected to
the12 volt powersource (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
inverterdoes not have the required start up capacity or your
battery supply isn’t large enough to operatethe equipment
or appliance in question.
Selecting the Optimum Power Source.
Operating the inverter forextended 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.
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 meetthe continuous load
demand of the equipment or appliance being operated.
INVERTER INFORMATION
Don’t Push It.
Although your Whistler power 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 1500 model has a maximum continuous
rating of 1500 watts. Although this model has the capacity
to briefly provide up to 3000 watts of power (that is, excess
current), it is designed to operate equipment and appli-
ances with start up load requirements of 1500 watts or less.
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.
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.
To determine whether your inverter will operate a particular
piece of equipment or appliance, run a test. The inverter is

BATTERY/CABLEINFORMATION
• It may be advisable to operate the inverter from a bank
of batteries of the same type in a "parallel" configura-
tion. Two such batteries will generate twice the
amp/hours of a single battery; three batteries will gen-
erate three times the amp/hours and so on.
This multiple parallel battery option is especially rec-
ommended for the WHISTLER 2000 series inverter due
to the high level of amps this model requires to pro-
duce up to 2750 watts of continuous load. For more
information regarding battery power please visit our
inverterfaq page atwww.whistlergroup.com/faq-invert-
ers.asp.
Wire Cable Gauges
For safeand proper operation of the inverter, connect the
inverter to the power source with the thickest wire available
and in theshortest length practical.
1000 Series
When the inverter and the batteryare setup within four feet
of each other, use a minimum of #4 gauge wire to make the
connections. Within fourto six feet, use a minimum of #2
gaugewire. At distances of morethansix feet,use #0 gauge
wire.
BATTERYINFORMATION
12
1. To calculate the amp/hour of the battery, first determine
its "reserve minutes" rating. (Deep cycle marine batter-
ies 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
reserveminutesratingof the batteryby 0.3 todetermine
the battery amp/hour rating of 50 (166 x 0.3 = 49.8).
2. To estimate the maximum battery powerthe inverterwill
require to run a pieceof equipment or appliance, divide
its continuous load wattage requirement by 10.
The WHISTLER 1000 watt model utilizes 50 amps of bat-
tery power to operate an appliance with a 500 watt con-
tinuous load requirement. (500 divided by 10 = 50).
3. Conclusion: The reserve power of the battery is suffi-
cient to satisfy the continuous load demand placed on
the inverter for a maximum of about one hour. (49.8
divided by 50 = 1 hour).
Note:
• When the inverter will be operating equipment or appli-
ances with high continuous load ratings for extended
periods, it is not advisable topower the inverter with the
same battery used to power your vehicle. If the car or
truck batteryis utilized for an extendedperiod, it is pos-
sible that the battery voltage may be drained to the
pointwhere the battery has insufficient reserve power to
start the vehicles.
1250/1750/2750 Manual 3/6/02 2:45 PM Page 15

Regardless of the wire gauge selected to make the connec-
tions 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 numberis listed
below:
O Ring Adapter: RSU11538139
2000 Series
When theinverter and thebattery are set up within four feet
of each other, use a minimum of #2 gaugewire to make the
connections. Within four to six feet, use two #0 gauge wire.
At distances of more than six feet, use two #0 gauge wires
connected in parallel to the battery. This connection will
require eight ORing Adapters as referenced above.
Alternatively, use #00 (2/0) gauge wire with the appropriate
adapters. These #00 gauge wire adapters are available
through most electronic supply stores.

CABLE INFORMATION OPERATION
Making the Connection.
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 series, remove
the supplied nutat each terminal onthe inverter, install
the wire connectors flush with the metal backing plates
and refasten the nuts securely. Do not over tighten
these nuts).
3. Connect the cable from the (BLACK) Negative (-) ter-
minal on the inverter (white on the 1000 series) 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 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 (red on all series) to the Positive (+) ter-
minal on the power source.

OPERATION OPERATION
connecting the ground, make certain that the invert-
er is turned off. Operating the inverter without
properly grounding it may result in electrical shock.
7. Turn the inverter ON (I). Check the Bar Graph Meter
on the front panel. The Voltage Bar Graph should
read between 11 and 14 volts depending on the volt-
age 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.
Neither the High Temperature or Over Load LED
Indicators should be illuminated.
8. Confirm that the equipment or appliance to be oper-
ated is turned off. Plug the equipment or appliance
into one of the two 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 connect-
ed to or disconnected from the 12 volt power source.
Again, this is normal.
• The use of an extension cord from the inverter to the
Note:
•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 per
-manent damage to the inverter. Damage
caused by reverse polarity is not covered
under the Whistler warranty.
•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.
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

appliance or equipment being operated will not signif-
icantly 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 out
put connections are secure. Loose connections
may damage the inverter, the power source, or
may generate excessive heat.
•The following precautions apply to the 2000 series
models only.
a). The AC receptacles are equipped with 15 amp cir-
cuit breakers. Consequently, each of these outlets is
rated for a maximum output of 1500 watts (110 volts x
15 amps).
To generate the maximum output, the 2000 series
models should be connected to a power supply which
has the capacity to produce up to 275 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.
b). The 2000 series models are designed for direct
wiring to an electrical distribution panel via the direct
wire connection "cut out" on the front panel of the
inverter.
This direct wire connection must be performed only by
a licensed electrician. Failure to make this connection
properly may result in severe injury.
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’reunsure.
Although we advise againstit, if you attempt to recharge
a chargingunit, monitorthe temperature of the charging
unit for approximately 10 minutes. If the charging unit
becomes unusually warm, disconnect it from the inverter
immediately.
The Power Source.
When the engine is off, most batteries will provide ample
power supplyto 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.

3. Isolate the television, its power cord and antenna cables
fromthe12voltpowersource byrunninganextensioncord
from the inverter to the television set.
4.Coil thetelevisionpowercordand theinputcables running
from the12 volt power source to the inverter.
5. Attach a"Ferrite Data Line Filter" to thetelevision power
cord. Morethanonefiltermayberequired.Thesefiltersare
available at most electronic supply stores including Radio
Shack. (Radio Shack Part Number is 273-105).
Note:
Inexpensive sound systems may emit a "buzzing" sound
when operated with theinverter. This is due to inadequate
filters in the sound system. There is nosolution tohis
problem short of purchasing a sound system with a higher
quality powersupply.
For You Microwave Chefs.
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 oper-
ating 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
appearonthebackofthemicrowave,checktheowner’sman-
ual or contact the manufacturer.
If you are using the inverter while the engine is off, we
recommend you start the engine every 30to 60 minutes and
let it run for at least 10 minutes to recharge the battery. We
also recommendthatthedevice plugged into the inverter be
turned off before turning over the engine.
Although itis notnecessary toturn offthe inverterwhen turn-
ing over the engine, the inverter may momentarily cease
operation asthe batteryvoltage decreases. When theinvert-
er is not supplying power, andturned on, it draws low amper-
agefrom the battery (<0.65 A ).
For You Television Fan & Audiophiles.
Althoughthe inverter is shielded and filtered to minimize sig-
nal interference, some interference with your television pic-
ture 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 walloutlet).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.

OPERATION
Some Powerful Advice.
Your Whistler inverter will work best when placed on a rea-
sonablyflatsurface. The floororwallofyour vehicle are good
locations.
When drivingwith the inverter inoperation, make certain that
neither the inverter nor the power cords will impede safe
operation ofyourvehicle. Keep the unitandallcords 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 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.
• 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.
•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.
•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.
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" ora "modifiedsinewave"asshownon the
following page.

In Review.
•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.
•Always make certain that the power cable terminal
connections run Negative (-) to Negative (-) and
Positive (+) to Positive (+). Check these connectionsfre-
quently to ensure that they are secure.
• Make certain the rated power consumptionof the appli-
ance or equipment you wish to operate is compatible
with the capacity of your inverter.

OPERATINGPRINCIPALS
This stepped waveform is similarto the power generated by
utilities and has a broad range of applications.
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
majorityof ACvoltmeters are calibrated for RMS voltage and
assumethatthemeasured waveformwillbeapuresinewave.
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."

OPERATION SUMMARY
•When in use, make certain that the inverter is proper-
ly ventilated.
•Do not use the inverter near flammable materials,
fumes, or gases.
•Always operate the inverter in accordance with the
instructions in this manual. Failure to do so may result
in property damage, personal injury, or loss of life.
•While connecting the inverter to the power source,
make certain that the inverter is well removed from
any potential source of flammable fumes or gases.
• Direct connection of the 2000 model inverter to a dis-
tribution panel is to be made by a licensed electrician
only.
•Always ground the inverter before operating it.
•In the event a continuous audible alarm or automatic
shut off, turn the inverter OFF immediately. Do not
restart the inverter until the source of the problem has
been identified and corrected.
