SmartAC®425W Power Inverter by Wagan Tech®

1www.wagan.com

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

User’s Manual—Read before using this equipment

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.

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.

Wagan Tech and wagan.com are trademarks of Wagan Corporation.

User’s Manual—Read before using this equipment

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.
