INTRODUCTION  
Your new Husky POWER INVERTER is one in a series of the most  
advanced DC to AC inverters available. With proper care and appropriate  
usage, it will give you years of dependable service in your car, truck, RV  
or boat.  
The POWER INVERTER supplies 750 watts of continuous power, with a  
1500 watt peak, in the form of two household-type outlets that are ready  
to deliver 110 volt AC power whenever and wherever you need it! The  
heavy-duty inverter has enough power to run most household or electronic  
appliances. It also comes equipped with battery clips to handle higher  
amperage/load applications, such as power tools, stereo amplifiers,  
vacuums, etc. Added safety features include automatic shutdown and a low  
battery alarm to prevent damage to your battery.  
This Power Inverter is configured with the latest Soft Start Technology (SST).  
Before introduction of Soft-Start, high start-ups currents from large  
inductive loads could shut down the inverter. Soft Start improves inverter  
operation. Three major features incorporated in SST include: first, gradual  
voltage ramp-up during inverter start-ups. This eliminates failed cold starts  
under load. Second, output that momentarily dips in voltage and quickly  
recovers to allow large motorized loads to start. This eliminates almost all  
shutdowns from momentary overloads. Last, the inverter automatically  
restarts when an overload that causes inverter shutdown is removed.  
Previously, manual reset was required.  
This power inverter also incorporates a new cooling technology that  
directly benefits our customers. The new design more efficiently cools the  
power transistors, and combined with Soft Start, dramatically increases  
reliability and the life of the product.  
Given proper care and appropriate use, your inverter is covered by a  
2-year initial warranty. You may extend the warranty an additional two full  
years by paying a small fee. See the Warranty Information at the end of  
this manual.

CONTROLS, INDICATORS AND CONNECTORS  
Figure 1 details the front panel of the inverter. The front panel provides two  
LED indicators. A green LED shows proper operation when lit. The red LED  
shows inverter shutdown from overload, over voltage or over temperature.  
Power is supplied through two grounded standard North American outlets.  
Outlets accommodate either two or three pin AC plugs. An On/Off Switch  
turns the inverter circuitry On and Off. The switch is used to force a reset  
of inverter circuits if it is switched Off, then On.

HOW YOUR HUSKY INVERTER WORKS  
The inverter converts low voltage DC (direct current) from a battery or other  
power source to standard 110 volt AC (alternating current) household power.  
3.1 PRINCIPLE OF OPERATION  
The inverter converts power in two stages. The first stage is a DC-to-DC  
conversion process that raises the low voltage DC at the inverter input to  
145 volts DC. The second stage is the actual inverter stage that converts the  
high voltage DC into 110 volts, 60 Hz AC.  
The DC-to-DC converter stage uses modern high frequency power  
conversion techniques that have replaced the bulky transformers found in  
less technologically-advanced models. The inverter stage uses advanced  
power MOSFET transistors in a full bridge configuration. This ensures  
excellent overload capability and the ability to operate reactive loads like  
lamp ballasts and small induction motors.

3.2  
THE POWER INVERTER OUTPUT WAVEFORM  
The AC output waveform of the POWER INVERTER is known as “modified  
sine wave”. It is a waveform that has characteristics similar to the sine wave  
shape of utility power. This type of waveform is suitable for most AC loads,  
including linear and switching power supplies used in electronic  
equipment, transformers, and motors.  
The modified sine wave produced by the POWER INVERTER has an RMS  
(root mean square) voltage of 110 volts, which is the same as standard  
household power. Most AC voltmeters (both digital and analog) are  
sensitive to the average value of the waveform rather than the RMS value.  
They are calibrated for RMS voltage under the assumption that the  
waveform measured will be a pure sine wave. These meters will not read  
the RMS voltage of a modified sine wave correctly. They will read about 20  
to 30 volts low when measuring the output of the inverter. For accurate  
measurement of the output voltage of this unit, use a true RMS reading  
voltmeter such as a Fluke 87, Fluke 8060A, Fluke 77/99 series, Beckman  
4410, or Triplett 4200.

INSTALLATION  
4.1 POWER SOURCE REQUIREMENTS  
The power source must provide between 11 and 14.5 volts DC and must  
be able to supply the necessary current to operate the load. The power  
source may be a battery or a well-regulated DC power supply. To obtain a  
rough estimate of the current (in amperes) the power source must deliver,  
simply divide the power consumption of the load (in watts AC) by 10.  
Example: If a load is rated at 750 watts AC, the power source must be able  
to deliver: 750 divided by 10 = 75 amperes

CAUTION: The POWER INVERTER must be connected only to batteries  
with a nominal output voltage of 12 volts. The unit will not operate  
from a 6 volt battery and will sustain permanent damage if connected  
to a 24 volt battery.  
4.2 CONNECTION TO POWER SOURCE  
The POWER INVERTER comes equipped with battery clip cables for  
connection to the power source.  
CAUTION: Do not use with positive ground electrical systems (the  
majority of modern automobiles, RVs, and trucks are negative ground).  
To operate at full 750 watts output, either use the battery clip cable  
(supplied) or directly wire to the power source with user supplied wire and  
fuse. Use wire #8AWG for lengths of four feet or less and #6 AWG for  
lengths to 10 feet.  
CAUTION: Reverse polarity connection will result in a blown fuse and  
may cause permanent damage to the inverter.  
Connecting to a Power Source Using Provided Cables:  
Use the provided cables to connect the POWER INVERTER directly to the  
12 volt power source using the following guidelines:  
1. Check to be sure the POWER INVERTER power switch is turned off and  
that no flammable fumes are present.  
2. Connect the black cable to the black post marked “(-)” on the back of  
the inverter. Connect the battery clip to the negative terminal of the battery.  
3. Connect the red cable to the red post marked “(+)” on the back of the  
inverter. Connect the battery clip to the positive terminal of the battery.  
4. Check to be sure that all connections between battery clips and  
terminals are secure.  
Direct Hardwiring to Power Source:  
Use #8 AWG wire if the inverter to power source connection is 4 feet or  
less. For longer cable lengths use #6 AWG wire. In either case, protect the  
positive (+) wire from shorts by installing a 150 to 200 Amp fuse or circuit  
breaker close to the DC power source (battery) terminal.  
 
7
1. Check to be sure the inverters power switch is turned off and that no  
flammable fumes are present.  
2. Identify the positive (+) and negative (-) DC power source (battery)  
terminals.  
3. Install a fuse holder or breaker close to the positive (+) terminal of the  
DC source (battery).  
4. Connect a length of wire on one side of the fuse holder or circuit  
breaker. Connect the other end of the wire to the Positive (+) terminal  
of the inverter.  
5. Connect a length of wire between the inverters negative (-) terminal  
and the DC power source negative (-) terminal.  
6. Connect a short length of wire to the other terminal of the fuse holder  
or circuit breaker. Mark it “POSITIVE” or “+”.  
7. Connect the free end of the fuse or breaker wire to the positive  
terminal of the DC power source (battery).  
8. Insert a 150 to 200 Amp fuse in the fuse holder.  
9. Test the inverter by turning it on and plugging in a 100 watt lamp or  
equipment.  
10. If the inverter is not properly operating, then refer to the trouble-  
shooting sections of this manual.  
CAUTION: Loose connectors may cause overheated wires and melted  
insulation. Check to make sure you have not reversed the polarity.  
Damage due to reversed polarity is not covered by our warranty.  
4.3 CONNECTION TO LOAD  
The POWER INVERTER is equipped with dual standard North American  
AC power receptacles. Plug the cord from the equipment you wish to  
operate into the AC receptacle(s). The green LED indicator lights to indicate  
that the inverter is functioning. Make sure the combined load requirement  
of your equipment does not exceed 750 watts.  
The POWER INVERTER is engineered to be connected directly to standard  
electrical and electronic equipment in the manner described above. Do not  
connect the Power Inverter to household or RV AC distribution wiring. Do  
not connect the Power Inverter to any AC load circuit in which the neutral  
conductor is connected to ground (earth) or to the negative of the DC  
(battery) source.  
WARNING: Do not connect to AC distribution wiring!

CAUTION: RECHARGEABLE APPLIANCES  
Certain rechargeable devices are designed to be recharged only by  
plugging them directly into an AC receptacle. These devices may  
damage the inverter. Do not use the inverter to recharge items that  
can be plugged directly into an AC receptacle.  
This problem does not occur with the majority of battery-operated  
equipment. Most of these devices use a separate charger or transformer  
that is plugged into an AC receptacle. The POWER INVERTER is easily  
capable of running most chargers and transformers.  
4.4 PLACEMENT OF THE INVERTER  
For best operating results, the inverter should be placed on a flat and/or  
solid surface. A power cord measuring 3 feet (1.0 meter) has been  
provided for easy positioning of the inverter. The inverter should only be  
used in locations that meet the following criteria:  
DRY - Do not allow water and/or other liquids to come into contact with  
the POWER INVERTER.  
COOL - Ambient air temperature should be between 30° F (-1° C) non-  
condensing, and 105° F (40° C). Do not place the inverter on or near a  
heating vent or any piece of equipment which is generating heat above  
room temperature. Keep the inverter away from direct sunlight, if at all  
possible.  
VENTILATED - Keep the area surrounding the inverter clear to ensure free  
air circulation around the unit. Do not place items on or over the inverter  
during operation. A fan is helpful if the inverter is operating at maximum  
power outputs for extended periods of time. The unit will shut down if the  
internal temperature exceeds 90° C. The unit will restart after it cools.  
SAFE - Do not use the inverter near flammable materials  
or in any locations that may accumulate flammable fumes  
or gases.

OPERATING TIPS  
5.1 RATED VERSUS ACTUAL CURRENT DRAW OF EQUIPMENT  
Most electrical tools, appliances and audio/video equipment have labels  
that indicate the power consumption in amps or watts. Be sure that the  
power consumption of the item you wish to operate is rated at 750 watts  
or less (If the power consumption is rated in amps AC, simply multiply by  
the AC volts (110) to determine the wattage). The inverter has overload  
protection, so it is safe to try to operate equipment rated at 750 watts or  
less. The inverter will shut down if it is overloaded. The overload must be  
removed before the inverter will restart. Resistive loads are the easiest for  
the POWER INVERTER to run. However, larger resistive loads, such as  
electric stoves or heaters, usually require more wattage than the POWER  
INVERTER can deliver on a continuous basis. Inductive loads, such as TVs  
and stereos, require more current to operate than do resistive loads of the  
same wattage rating. Induction motors, as well as some televisions, may  
require 2 to 6 times their wattage rating to start up. The most demanding  
in this category are those that start under load, such as compressors and  
pumps. Testing is the only definitive way to determine whether a specific  
load can be started and how long it can run. The unit will simply shut down  
if it is overloaded. To restart the unit after a shutdown due to overloading,  
remove the overload.  
CAUTION: This inverter will not operate high wattage appliances or  
equipment that produce heat, such as hair dryers, microwave  
ovens, and toasters.  
5.2 BATTERY OPERATING TIME  
With a typical vehicle battery, a minimum operating time of 2 to 3 hours  
can be expected. In most instances, 5 to 10 hours of operating time is  
achievable. However, Husky recommends that the operator start the vehicle  
every 2 to 3 hours to recharge the battery system. This will guard against  
any unexpected shut-down of the equipment and will ensure that there is  
always sufficient battery capacity to start the vehicles engine. The inverter  
will sound its alarm when DC voltage drops to 10.6V.  
The inverter may be used whether or not the vehicles engine is running.  
However, the inverter may not operate while the engine is starting since the  
battery voltage can drop substantially during cranking. The inverter draws  
less than 0.3 ampere from the battery when it is not supplying power to a  
load. In most instances, the inverter can be left connected to the battery  
when not in use since it draws so little current. However, if the vehicle is to  
remain unused for several days, disconnect the inverter from the battery.

PROTECTIVE FEATURES OF THE INVERTER  
Your POWER INVERTER monitors the following potentially hazardous  
conditions:  
Low Battery Voltage - This condition is not harmful to the inverter but could  
damage the power source. An audible alarm will sound when input  
voltage drops to 10.6. The POWER INVERTER automatically shuts down  
when input voltage drops to 10.0 volts. When the condition is corrected,  
the unit may be restarted.  
Over Voltage Protection - The POWER INVERTER will automatically shut  
down when the input voltage exceeds 15 volts DC.  
Short Circuit Protection - Reverse polarity or a short circuit condition will  
usually result in an external or internal fuse being blown.  
Overload Protection - The inverter will automatically shut down when the  
continuous draw exceeds 750 watts. When the overload is removed the  
inverter will self-start.  
Over Temperature Protection - When the temperature sensor inside the  
POWER INVERTER reaches 150 degrees F, the unit will automatically shut  
down. Allow the unit to cool for at least 15 minutes before restarting after  
a heat-related shutdown. Unplug unit while cooling.  
Low Battery Alarm - An alarm will sound when the voltage from the battery  
drops to 10.6 volts. This is an indication that the battery needs to be  
recharged. The user should stop operation of the electronic device at this  
time, since the inverter will shut down automatically shortly thereafter, when  
the battery voltage drops to 10 volts. Start your engine to recharge the  
battery.  
If the low voltage alarm sounds when the battery is fully charged, follow  
the steps for solving lack of output power in the Troubleshooting Guide. The  
alarm will sound when the inverter is overloaded, in thermal shutdown, or  
if there is an excessive voltage drop between the battery and inverter.  
NOTE: It is normal for the alarm to sound while the unit is being connected  
to, or disconnected from, the power source. This is not indicative  
of a problem.

7.  
COMMON PROBLEMS  
“Buzzing” sound in audio systems:  
Some inexpensive stereo systems and “boom boxes” emit a buzzing sound  
from their speakers when operated from the POWER INVERTER. This  
occurs because the power supply in the electronic device does not  
adequately filter the modified sine wave produced by the inverter. The only  
solution to this problem is to use a higher quality sound system that  
incorporates a higher quality power amplified supply.  
Television Interference:  
The Husky POWER INVERTER is shielded to minimize interference with TV  
signals. However, in some instances, some interference may still be visible,  
particularly with weak TV signals. Try the following corrective measures:  
Position the inverter as far as possible from the television, the antenna  
and the antenna cables. Use an extension cable, if necessary  
• Adjust the orientation of the inverter, the antenna cables and the TV  
power cord to minimize interference  
• Make sure that the antenna feeding the television provides an adequate  
(“snow free”) signal and that high quality, shielded antenna cable is used

FUSE REPLACEMENT  
If external fuses blow, (or breakers trip), then there is a short or overload  
in the DC wiring. Find and fix the problem before replacing the fuses  
(or resetting the breaker). After fuse replacement, reconnect the inverter.  
This power inverter is equipped with multiple internal fuses. Normally,  
these fuses will not blow unless there is a serious problem inside the unit.  
Internal fuses are replaceable, however, only electronically knowledgeable  
people should attempt fuse replacement. If the unit is damaged during fuse  
replacement, the warranty may be voided. Husky recommends contacting  
Technical Support for guidance. Based on experience, it is best to return  
the unit to Husky for repair. Husky Technical Support can be reached  
by calling 954-584-4446, extension 19.
