INTRODUCTION
Thank you for purchasing a Wagan Tech®SmartAC®425W Power Inverter. With
minimal care and proper treatment, it will provide years of reliable service.
This power inverter converts direct current (DC) to alternating household current
(AC). This inverter operates from a DC power source only. The level of direct
current allowed by this inverter is 12V DC.
In an industry where the actual wattage output varies so greatly, Wagan Tech
is proud to introduce TrueRated Power™technology. All our inverters feature
TrueRated Power. That simply means power tested and rated at a period of
24 hours continuous usage under full load. Many competing products claim
“continuous duty”, when they are often only 20 minutes of “continuous” duty at
full output. We also build our inverters with High Peak Surge rating to support
motorized appliance start up.
Read and understand this manual before installing and operating this
inverter. Keep this manual for future use.
FEATURES
• Two LED indicators display the operating status of the inverter.
• Multiple AC outlets allow for more than one appliance to be powered at the
same time.
• High Peak Power: Allows you to power appliances that require large initial
start-up wattage.
• Low Battery Alarm: The inverter sounds an audible alarm then turns itself off
if the battery voltage becomes too low.
• Auto Shutdown/Reset Protection: The inverter temporarily shuts itself down
to protect itself from overheating.
• Overload Protection: The inverter automatically turns itself off if the
connected load is too large.

WARNINGS
• Do not attempt to open the inverter enclosure. High voltage inside the unit is
the same type of power as your electrical outlets at home.
• Do not operate the inverter in or around water. The voltage of the unit
makes it an electrical shock hazard if operated in wet conditions. Do not let
any plugged in appliance’s cord get wet.
• Do not connect the AC inverter directly to another AC power source.
• Keep it away from children: The inverter produces power just like AC wall
outlets at home and it should be treated seriously.
CAUTIONS
• Do not use the inverter in a positively grounded vehicle.
• Allow at least 2 inches of clearance around the inverter for air flow.
• If you operate the inverter in a moving vehicle, you need to secure the
inverter to prevent it from shifting around while the vehicle is moving.
• If there is anything wrong with the inverter, disconnect all power.
• The following operations will damage and void the warranty of the inverter:
• Reversing polarity by connecting DC cables to incorrect terminals.
• Connecting the inverter to a power source greater than 15V DC

Audible Alarm (not shown) – when it sounds, it indicates that the battery voltage
is getting low and the inverter is about to shut down. If you can reduce the AC
load, you can temporarily extend operating time. Charge the battery as soon as
possible.
REAR PANEL
All inverters described in this manual have two terminals for connecting battery
cables. One terminal is the Positive (+) terminal [red]; the other is the Negative (−)
terminal [black]. The Positive battery cable should have a Battery Protection Fuse
installed within one foot of the battery connection. The negative cable can be
directly attached to the negative battery terminal. In some cases, a metal vehicle
frame can be used as part of the negative cable to the battery.
Cooling Fan (internal)
Positive Terminal (red)
Negative Terminal (black)
High Speed Fan – The fan turns on when there is a high load or an elevated
temperature to keep the inverter cool. Do not block. Keep 2-inch clearance.
MEASURING THE AC VOLTAGE
This inverter’s AC output is a modified sine wave (MSW) 115 volts AC. Your
household AC output is pure sine wave. The comparison of modified sine wave
and household AC is shown in the figure below.

SmartAC®425W Power Inverter by Wagan Tech®
5www.wagan.com
(Pure sine wave)
This modified sine wave has a root mean square (RMS) voltage of 115 volts. Most
ordinary AC voltmeters are calibrated to read “average” voltage and assume that
the AC waveform will be a pure sine wave. These meters will not correctly read
MSW voltage, and will display about 20 to 30 volts too low. Any multi-meter
identified as “TRUE RMS” will accurately read MSW correctly.
PRODUCT USAGE
Maximum Power from Vehicle Accessory Sockets
Most vehicle accessory sockets that are controlled through a vehicle’s ignition
switch are fused at 15 amps. This limits inverter output to approximately 180
watts.
To Power 425 Watt Appliances: For temporary use, connect a battery clip
adapter cord to the inverter and follow the procedure located under the
“Connecting the Inverter” section.
There is no danger in leaving the inverter directly wired to the battery if the
inverter is turned off after each use. The inverter will shut off when the vehicle’s
battery level drops down to 9.5 volts to protect the battery from draining
completely.
Determining Maximum Appliance Wattage
Do not exceed the 425 watt maximum AC load or the inverter will shut
down.

Most electrical tools, appliances, and audio/video equipment have labels that
list the unit’s power requirements in watts. If the tool or device is rated in amps,
multiply the amps by 120 (120V AC) to determine the watts. For example, an
appliance rated at 0.5 amps will draw 60 watts.
WATTS = VOLTS × AMPS
Remember to consider the startup surge that motorized appliances will cause. Do
not exceed the 825 watt momentary surge rating of this inverter. This can cause
immediate overload shut down and or blow a fuse.
BASIC OPERATION
• Turn ON the power switch that is located at the front of the inverter, and the
green LED indicator will light up as an indicator that the unit is working.
• Plug your appliance(s) into the AC socket(s) at the front of the inverter.
INSTALLATION
Connecting the Inverter
Loose DC (battery) connections will result in a severe voltage drop that can cause
damage to connectors, conductors, and insulation and can cause sparking.
Reverse polarity connection can permanently damage the inverter. Damage
caused by reverse polarity will void the warranty.
CAUTION: Making an initial connection between the positive cable end and
the inverter’s positive terminal may cause a spark. This is normal and is a result
of capacitors in the inverter starting to charge. Because of the possibility of
sparking, it is extremely important that both the inverter and the battery bank be
positioned away from any source of flammable fumes or gases. Failure to heed
this warning can result in fire or explosion. Do not make the positive terminal
connection immediately after the batteries have been charging. Allow time for
the battery gasses to vent to outside air.

Installation Procedure
1. Mount the inverter in a secure location. If the inverter is to be mounted on a
wall, mount it horizontally. Make sure that the front and rear of the inverter
has free air flow.
2. Make sure the ON/OFF switch located on the front panel of the inverter is
in the OFF (O) position.
3. Connect the cables as follows:
• If using the DC Plug Adapter Cord—Up to 180W Output:
i. Connect the red (+) and black (−) terminals of the supplied DC Plug
Adapter Cord to the red (+) and black (−) terminals on the rear of the
inverter.
• Be sure to connect them into the correct polarity terminals on the
rear of the inverter. Reverse polarity connection will blow the
fuse in the inverter and can permanently damage the inverter.
Damage caused by reverse polarity will void the warranty.
ii. Connect the Plug end of the DC Adapter Cable into your vehicle’s 12V
DC accessory outlet. You may need to place the ignition switch to
Accessory Position if the vehicle engine is not operating.
• If using the Battery Clip Adapter Cord—Up to 425W Output:
i. Connect the Negative (−) cable end to the inverter terminal and
battery’s Negative Terminal. Make sure you have good, secure
connections.
ii. Attach the positive cable to the Positive (+) DC connector on the
battery and then the inverter. Make sure the connections are tight and
secure .
4. Turn on the inverter from the Front Panel ON/OFF Switch.
5. Make certain that the green Operating LED is lit and the red FAULT LED
indicator is not lit.

6. Turn OFF (O) the inverter. The Fault LED may briefly flash; this is normal. The
audible alarm may also sound a short chirp; this is also normal.
7. When you have confirmed that the appliance to be operated is turned off,
plug the appliance into one of the AC outlets on the inverter.
8. Turn the inverter on.
9. Turn the appliance on. The appliance should begin working.
10. Observe the LED indicators for normal operation.
If flooded lead acid batteries are used, be sure that periodic checks of battery
electrolyte levels are accomplished. Follow battery manufacturer’s instructions
in keeping the electrolytes at the proper level. Be sure to use pure distilled water
when replacing evaporated electrolyte liquid.
RECOMMENDATIONS
• If the power inverter makes a beeping sound, turn OFF the inverter,
disconnect all appliances from the inverter. The beeping sound is the low
battery warning that indicates that the voltage of the battery power supply
is getting low. Please restart the vehicle engine to charge the battery before
using it to operate the inverter again.
• When you are not using the inverter, turn the power switch to OFF. This
conserves battery power.
OPERATING TIPS
Adding an Extension Cord
You may use up to 100 feet of high quality, heavy-duty extension cord. A longer
cord will result in reduced power to appliances.
Buzz in Audio Systems
Some stereo systems and portable radios will emit a buzzing noise from their
speakers when operated from the power inverter because the power supply in

SmartAC®425W Power Inverter by Wagan Tech®
9www.wagan.com
the device does not adequately filter the modified sine wave produced by the
power inverter. The only solution is to use a sound system that incorporates a
higher quality power supply.
Television Interference
Operating the power inverter can interfere with television reception on some
channels. If this situation occurs, the following steps may help to alleviate the
problem:
• Do not operate high power loads with the power inverter while watching
television.
• Make sure the antenna feeding your television provides an adequate static-
free signal and you are using good quality cable between the antenna and
the television.
• Move the television as far away from the power inverter as possible.
• Keep the cables between the battery and the power inverter as short as
possible and twist them together with about 2 to 3 twists per foot. This
minimizes radiated interference from the cables.
• Ferrite beads may be installed around battery cables and AC appliance
cords to reduce noise.
MAINTENANCE
Very little maintenance is required to keep the inverter operating properly.
Periodically check to ensure all terminals and connectors are secure and tight.
HEAT DISPERSAL
The inverter generates heat while it is working. This is not a malfunction.
However, if the inverter gets too hot while working, it will turn off by itself.
Position the inverter where air flows freely around it to allow the heat to disperse.
The inverter’s thermal protection prevents it from operating when its temperature
exceeds 130ºF ± 10ºF.

MEDICIÓN DE TENSIÓN CA
La salida CA de este inversor es una onda sinusoidal modificada (MSW)
de 115 voltios CA. La salida CA doméstica es una onda sinusoidal pura. La
comparación de la onda sinusoidal modificada y la CA doméstica se muestra en
la imagen siguiente.
(Pure sine wave)
(Onda sinusoidal pura) (onda sinusoidal modificada)
Esta onda sinusoidal modificada tiene una tensión de raíz cuadrada media
(RMS) de 115 voltios. La mayoría de voltímetros CA habituales están calibrados
para leer la tensión “media” y asumen que la forma de onda CA será una onda
sinusoidal pura. Estos medidores no leerán correctamente la tensión MSW, y
mostrarán aproximadamente entre 20 y 30 voltios menos. Cualquier multímetro
identificado como “RMS AUTÉNTICO” leerá correctamente y con precisión
la MSW.
USO DEL PRODUCTO
Potencia máxima de enchufes para accesorios vehiculares
La mayoría de los enchufes para accesorios de vehículos que se controlan a
través del interruptor de encendido tienen un fusible de 15 amperios. Esto limita
la salida del inversor a aproximadamente 180 vatios.
Para alimentar electrodomésticos que requieres de 425 vatios: Para uso
temporal, conecte un cable adaptador con pinzas al inversor y siga el
procedimiento que se encuentra en la sección “Conexión del inversor”.
