INTRODUCTION

Thank you for purchasing a Wagan Tech®Slimline™Plus 1250 Power Inverter. With

minimal care and proper treatment, it will provide years of reliable service.

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

• LED display panel shows the operating status of the inverter.

• Multiple AC outlets allow for more than one appliance to be powered at

the same time.

• Mounting holes allow for safe stable installation.

• 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/Short Circuit Protection: The inverter automatically turns itself off

if the connected load is too large or if it shorts.

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.

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.

(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.

BASIC OPERATION

• Press the ON/OFF Switch that is located at the front of the inverter, the

Input/Output Display 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.

• To turn inverter off, press the ON/OFF Switch.

PLANNING THE INVERTER SYSTEM

Any large wattage inverter system requires planning before installation. There are

several steps to the planning process so the user must determine the following:

• Maximum inverter wattage required.

• Operating time (run time) needed between battery recharges.

• Battery bank capacity in amp-hours.

• Charger requirement to charge batteries within a practical time.

• Distance between battery bank and inverter.

DETERMINING MAXIMUM APPLIANCE WATTAGE

Maximum AC Appliance Wattage is the ﬁrst factor in planning battery and

charging systems. Some background:

Large microwave oven speciﬁcations list cooking power (watts) and appliance

power. Appliance power is the AC load the inverter has to supply.

Most other 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 115 (115V AC) to determine the watts. For example,

a power tool rated at 4-amps will draw 460 watts.

Determine the wattage of each appliance you need to simultaneously operate.

Add all of the appliance wattages to obtain an estimated “total watts” number.

Remember to consider the start-up surge that motorized appliances will cause.

Do not exceed the surge rating of this inverter. This can cause immediate

overload shut down.

At maximum continuous output, this inverter requires a DC power supply (battery

bank) that can continuously supply 125 amps @ 12V for the duration of the run

time.

CONFIGURING THE BATTERY BANK

To determine the minimum battery ampere-hour rating that you will need to

operate appliances from the inverter, and any DC appliances powered by the

battery bank, follow these steps:

(The following calculations are speciﬁc to 12V systems.)

1. List the maximum continuous wattage that the inverter has to supply.

2. Estimate the number of hours the appliances will be in use between

battery recharges. This will vary depending on appliances.

For example, a typical home-use coffee maker draws 500 watts during its

brew time of 5 minutes, but it only requires 100 watts thereafter to maintain

the temperature of the pot. Similarly, a typical use of a microwave oven is

only for a few minutes. Some longer operating time appliances are lamps,

TV’s, computers, and refrigerator/freezers.

3. Determine the total watt-hours of energy needed. This is done by

multiplying average power consumption in watts by hours of run time. For

example: 1,000 watts for 10 hours = 10,000 watt hours.

To get an estimate of the maximum current (in amps) that a battery bank must be

capable of delivering to the inverter, divide the load watts by 10. For example a

1,000 watt appliance load will need 100 amps at 12 Volts DC.

Using the 1,000 watts for 10 hours example as above, then 100 amps is

needed for 10 hours. This provides us with the basic amp-hours (Ah) of battery

that is required. Ten hours at 100 amps equals 1,000 Amp Hours (Ah). This

answer is just a beginning of conﬁguring the battery bank because there are

additional factors that determine actual run time. These include:

• AC appliance load and time in use (basic Ah)

• Cable gauge and length (cable losses)

• Charge level of the batteries (between use, chargers have to be able to

fully charge the batteries)

• Temperature of the batteries (colder batteries provide fewer amps)

• Age and condition of the batteries (older batteries lose Ah capacity)

• Compliance with turning off unnecessary AC loads

• Use of DC appliances and compliance with turning off unnecessary DC

loads

• If the inverter is installed in a vehicle and the alternator output in Amps

cannot supply enough current for the inverter, additional batteries are

required to supply the required current.

DERATING THE BATTERY BANK

Most lead-acid batteries have a rating expressed in amp-hours (Ah). The most

common rating of Ah is at the “20-hour rate”.

For example, if a 20Ah battery is discharged at a 1 amp rate, it will take 20

hours to discharge that battery. The terms “charged” and “discharged” relate to

actual battery voltage. This means that the output voltage of a nominal 12 volt

battery starts at 13.2 volts (fully charged) then drops to 10.6 volts (discharged).

If the load on the battery causes the battery to discharge faster than the 20 hour

rate, the capacity (Ah) of the battery is measurably reduced (derated). Derating

is a major run time factor. Some benchmarks are as follows:

• If an 100 Ah Battery is discharged at 100 Amps, the battery capacity acts

like a 56 Ah battery.

• If an 100 Ah Battery is discharged at 200 Amps, the battery capacity acts

like a 32 Ah battery.

Again, both high discharge rates are faster than the 20-hour rate so battery

capacity seems lower.

INSTALLATION

Safe installation requires that a Battery Protection fuse is installed within one foot of

the positive (+) battery Terminal [red]. Use ANL marine fuses or equal because they

do not spark when they blow. Use an appropriate fuse holder for the fuse. ANL

fuse holders can be mounted so they do not move in a vehicle or vessel.

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.

WARNING:

Venting batteries produce explosive, corrosive gases. There is danger of

explosion. DO NOT connect or disconnect BATTERY cables directly after battery

discharge or recharge. Make sure that the battery bank area is well vented

before attaching or removing cables.

NOTES: All recommended cable gauges and fuse sizes are located at the rear

of this manual in the Cable Gauge Table. The table describes Cable Gauges for

lengths greater than supplied cables.

“Round Trip” refers to actual cable distance in feet from the POS (+) battery

terminal to the inverter and back to the NEG (−) battery terminal.

Crimp-on ring terminals are required on all cable ends. The cable ends need to

be stripped of insulation for ½ inch before crimping on ring terminals. Select

a crimp terminal size to ﬁt the cable gauge and inverter and battery terminal

connectors. After crimping, make sure that the cable connectors are secure on

the cables so there are no loose connections.

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.

GROUND TERMINAL WIRE REQUIREMENTS

Use a minimum of 6 gauge stranded wire for enclosure ground wire. Connect

this to the chassis of your vehicle or to the grounding system in your boat. In

a city, the ground wire can connect to a metal cold water pipe that goes

underground. In remote locations, the ground wire can be connected to an

“earth ground”. This can be an attachment to a 6 foot long copper clad metal

rod driven into the ground. In the unlikely event of a short circuit, operating the

inverter without proper grounding can result in electrical shock. Do not directly

connect this ground to the negative terminal on the inverter.

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 cables are the proper gauge and have the fuse holder as

close to the battery bank’s Positive (+) terminal as possible.

3. Install the fuse in the Positive (+) cable (Refer to the Cable Gauge Table at

rear of manual).

4. Install the ground wire from the ground terminal to the grounding point.

5. Connect the Negative (−) cable end to the inverter terminal and battery's

Negative Terminal. Make sure you have good, secure connections.

6. Recheck and make sure the DC cable fuse is installed in the fuse holder.

7. Attach the positive cable to the Positive (+) DC connector on the battery

and then the inverter. Make sure the connections are tight and secure.

8. Turn on the inverter from the Front Panel ON/OFF Switch.

9. Make certain that the LED display is reading normal with no errors

displayed.

10. 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.

11. 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.

12. Turn the inverter on.

13. Turn the appliance on. The appliance should begin working.

14. Observe the LED display 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.
