INTRODUCTION

Dear Whistler Owner,
For many of us, a vehicle is more than just transportation. It

can be a mobile office, communications or entert a i n m e n t
c e n t e r, or simply an expression of our personality. Whistler
p roducts are designed to make the time you spend in your
vehicle more productive, more fulfilling, safer, or just simply
m o re fun. Our mission is to provide products that impro v e
your driving experience.

Whistler offers a complete line of DC to AC inverters
ranging in capacity from 140 Watts to 2750 Watts. These
inverters offer advanced technology, dependable operation
and will provide years of reliable service when used in accor­dance with our operating instructions.

Your new Whistler GO AC power inverter allows you to ru n
most AC appliances right from your car, boat or RV. They’re
g reat for weekend use and life on the road. They’re also gre a t
for power outages!

To fully acquaint yourself with the operation of the Whistler
PP750AC we recommend reading this entire manual.

Sincerely,
THE WHISTLER GROUP

We’re Driving Technology

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 inform a t i o n .
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

I m p o rtant Information About Your New W h i s t l e r
Inverter.

This manual will provide you with directions for the safe
and efficient operation of your Whistler GO-AC 750 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.

• 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.

• 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.

• Check with the appliance manufacturer for com-
patibility 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 w w w. w h i s t l e rg ro u p . c o m / f a q -

This is especially true for medical equipment.

INVERTER BASICS

Getting Start e d

Power equipment and appliances which operate with motors
or tubes re q u i re an initial surge of power to get them up and
running. This power surge is re f e rred to as the "starting load"
or "peak load." (By comparison, electrical devices such as
s t a n d a rd light bulbs do not re q u i re a large starting load).
Once the equipment or appliance has been powered up, it
settles down to a slower pace and re q u i res far less electrical
power to operate. This lower power re q u i rement is re f e rre d
to as the "continuous load."

In order to ensure that the capacity of your Whistler i n v e rt e r
is sufficient to meet the re q u i red start up load, you must first
d e t e rmine the power consumption of the equipment or
appliance you plan to operate.

Power consumption is rated either in wattage or in ampere s ,
and information re g a rding the re q u i red "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. 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.

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
re q u i red start up load by multiplying the wattage rating by 10.

"Technical Operating Principles"

INVERTER BASICS

Don’t Push It.

Although your Whistler GO AC inverter has the capacity to
p rovide power output (excess current) equal to appro x i­mately 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 750 model has a maximum continuous rat­ing of 750 watts. Although this model has the capacity to
briefly provide up to 1500 watts of power (that is, excess cur­rent), it is designed to operate equipment and appliances
with start up load re q u i rements of 750 watts or less.

C o n s e q u e n t l y, 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 invert e r, the inverter will
attempt to start loads above the continuous rating for up to
10 seconds.

To determine whether your inverter will operate a part i c u l a r
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
s t a rt up load ratings comparable to your inverter wattage
rating will not damage it.

INVERTER BASICS

If a piece of equipment or an appliance will not operate, first
c o n f i rm 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 invert e r
rocker switch ON (l), OFF (O) and ON (l) again in quick suc­cession. If this pro c e d u re is unsuccessful, it is likely that the
i n v e rter does not have the re q u i red start up capacity to
operate the equipment or appliance in question.

Note:

• Most heat generating appliances re q u i re start up loads
in excess of 1000 watts and the PP750AC inverter will
not operate such appliances as coffee makers, iro n s ,
hair dryers or heaters.
