About PowerBright Inverters
PowerBright, an innovator in portable inverter design, has developed a new line of
super-efficient power inverters with the highest surge capability in the industry. These
extremely advanced, microprocessor controlled units run cooler and more reliable
than any in their class. Their superior surge capability allows them to start even the
most difficult loads, including color televisions, TV/VCR combinations, microwaves,
refrigeration units, and even small air conditioners! They also boast the highest
efficiency available (up to 90%), which translates into longer running time and
extended battery life.
PowerBright Inverters convert low voltage, direct current (DC) to 220 volt alternating
current (AC). Depending on the model and its rated capacity, the inverters draw
power either from standard 12 volt automobile and marine batteries or from portable
high power 12 volt sources.

Getting Started
When turning on an appliance or a tool that operates using a motor, it requires an
initial surge of power to start up. This surge of power is referred to as the "starting
load" or "peak load."
Once started, the tool or appliance requires less power to continue to operate. This is
referred to as the "continuous load" in terms of power requirements.
You will need to determine how much power your tool or appliance requires to start
up (starting load) and it's continued running power requirements (continuous load).
Power consumption in rated either in wattage (watts), or in amperes (amps), and this
information is usually stamped or printed on most appliances and equipment. If this
information is not indicated on the appliance or equipment, check the owner's manual
or contact the manufacturer to determine if the device you are using is compatible
with a modified sine wave.
Multiply: AMPS X (AC voltage) = WATTS
This formula yields a close approximation of the continuous load of your appliance.
Multiply: WATTS X 2= Starting Load
This formula yields a close approximation of the starting load of your appliance.

A Larger Inverter May Be Required
To determine whether the PowerBright ERP23 00-12 will operate a particular piece of
equipment or appliance, run a test. All inverters are designed to automatically shut
down in the event of a power overload. This protection feature prevents damage to
the unit while testing appliances and equipment with ratings in the 23 00 watt range.
If an appliance in the 23 00 watt range will not operate properly when first connected
to the inverter, turn the switch ON (I), OFF(0),and ON(I) again a quick succession. If
this procedure is not successful, it is likely that the Power Bright inverter does not
have the required capacity to operate the appliance in question
Important:
Your PowerBright inverter is designed to operate from a 12V power source only. Do
not attempt to connect the inverter to any other power source, including any AC
power source. Do not attempt to extend or otherwise modify the connector cables
provided with your inverter. 220V of current can be lethal. Improper use of your
inverter may result in property damage, personal injury or loss of life.

A. ON/OFF Switch. The current flowing from the power source to the inverter is
controlled by this switch.
B. Overload LED Indicator Light. If the continuous power draw of the appliance(s)
being operated exceeds 23 000 watts, this light will turn ORANGE/RED and the
inverter will automatically shut down. When this occurs, turn off the inverter and
determine the cause of the overload before turning the inverter and the appliance
back on.

Selecting A Power Supply
When you operate the ERP2300-12 inverter for long periods of time combined with a
high continuous load demand, the result will be a large power drain from the battery.
With this in mind, check the reserve capacity of the battery you plan to use to power
your inverter. To calculate the approximate power drain on your battery you will want
to estimate the reserve power ("amp/hour") of the battery and the amps the inverter
will require, to meet the continuous load demand of the appliance.
1. When calculating the amp/hour of the battery, find its reserve minutes rating.
This is typically is marked on the battery label along with the "Cold Cranking
Amps" (CCA) rating. If you multiply the reserve minutes rating of the battery
by 0.3 it will tell you the battery amp/hour.
2. To estimate the maximum battery power the inverter will require to run a
piece of equipment or appliance, divide its continuous load wattage
equipment by 10.
3. Conclusion: The reserve power of a battery with a 150 reserve minutes
rating is sufficient to satisfy the continuous load demand placed on the
inverter for a maximum of about one hour. (45 amps/hour-amp draw = 1
hour).
Note:
The type of battery you use to power your inverter is important. Batteries designed to
start engines have multiple layers of very thin plates. These provide extensive
surface area that will produce a powerful short burst of electrical power required to
start combustion engines. Using an inverter will cause a battery to discharge and
recharge often. We recommend that you use a different type of battery that is
designed specifically for this type of load requirement. Deep cycle (marine) batteries
generally have the highest reserve ratings. They are designed with thicker plates
making them capable of withstanding repeated complete drains of power and
recharging. If you do not have a deep cycle battery we recommend that you run the
engine of your vehicle when operating the inverter.

PAGE 8
Connection Cable Gauges
When connecting the inverter to the power source use the thickest wire available, in
the shortest length practical.
If the inverter and the battery are positioned within four feet of each other, a minimum
of # 4 gauge wire should be used to make the connections. When the distance
between them is four to six feet, a minimum of #2 gauge wire is required.
Connecting Your Inverter
1. Make sure the ON/OFF switch located on the front panel of the inverter is in
the OFF (O) position.
2. Connect the wires to the power input terminals at the rear of the inverter.
Make sure to match the negative (Black) terminal on the inverter with one
wire that connects to the negative terminal on the 12 volt power source.
Then repeat this procedure with the positive (Red) terminal connecting a
wire to the positive terminal of the 12v volt power source. Make sure you
have a good secure connection, but do not over tighten these screws.
Mounting the Inverter
Your PowerBright Inverter should not be mounted under the hood of a vehicle. If
installed in a vehicle, choose a dry, cool, ventilated area closest to the battery source
as possible.
To mount the E RP2300-12:
1. Inverter must be in the OFF position.
2. The inverter can be mounted vertically or horizontally. If mounted vertically, make
sure the ventilation openings are pointing downwards.
3. Hold the inverter against the mounting surface, mark the positions of
the mounting screws, and then remove the inverter.
4. Pilot drill the four mounting holes.
5. Fasten the inverter to the mounting surface using corrosion-resistant fasteners
sized #10 or larger.

PAGE 9
Note:
Loose connections can result in a severe decrease in voltage which may cause
damage to the wires and insulation. Failure to make a proper connection between
the inverter and the power source will result in reverse polarity. Reverse polarity will
blow the internal fuses in the inverter and may cause permanent damage to the
inverter. Damage caused by reverse polarity in not covered under the PowerBright
warranty. Making the connection between the Positive terminals may cause a spark
as a result of current flowing to charge capacitors within the inverter. This is a normal
occurrence. Due to the possibility of sparking, however, it is extremely important that
both the inverter and the 12 volt battery be positioned far from any possible source of
flammable fumes or gases. Failure to heed this warning could result in fire or
explosion.
1) Locate the Ground Lug Terminal at the rear of the inverter. Run a wire from
this terminal to a proper grounding point using the shortest practical length
2 AWG wire. You can connect this wire to the chassis of your vehicle or to
the grounding system in your boat.As an alternative when in remote
locations the ground wire can be connected to the earth (one way to
accomplish this is to attach it to a metal rod driven into the ground). Before
connecting the ground, make certain that the inverter is turned off.
Operating the inverter without correctly grounding the unit may result in
electrical shock.
2) Turn On (I) the inverter. Make certain the Over Load LED Indicators are not
lit.
3) Turn OFF (0) the inverter. The Over Load LED may briefly "blink". This is
normal. The internal audible alarm may also sound a short "chirp." This is
also normal.
4) When you have confirmed that the appliance to be operated is turned off,
plug the appliance into one of the two 220v AC Outlets on the front panel of
the inverter.
5) Turn the inverter on.
6) Turn the appliance on.

PAGE 10
Note:
The audible alarm may make a momentary "chirp" when the inverter is turned OFF
(O). This same alarm may also sound when the inverter is being connected to or
disconnected from the 12 volt power source. When using an extension cord from
the inverter to the appliance the extension cord should be no more than 50 feet
long. At this length there should be no measurable decrease in power from the
inverter.
Television and Audio Suggestions
Although all PowerBright inverters are shielded and filtered to minimize signal
interference, some interference with your television picture may be unavoidable,
especially with weak signals.
However, here are some suggestions that may improve reception.
1. First, make sure that the television antenna produces a clear signal under
normal operating conditions. Also, ensure that the antenna cable is
properly shielded and of good quality.
2. Change the positions of the inverter, antenna cables and television power
cord.
3. Isolate the television, its power cord and antenna cables from the 12 volt
power source by running an extension cord from the inverter to the
television set.
4. Coil the television power cord and the input cables running from the 12
volt power source to the inverter.
5. Attach a "Ferrite Data Line Filter" to the television power cord. More than
one filter may be required. These filters are available at most electronic
supply stores.
Note:
Some inexpensive audio systems may discharge a slight "buzzing" sound
when operated with the inverter. This is caused by deficient filters in the audio
system. The only solution to this problem is using a sound system with a higher
quality power supply.

PAGE 11
Operating a Microwave oven with Your Power Inverter
The power rating used with microwave ovens is the "cooking power" which means the
power being "delivered" to the food being cooked. The actual operating power
requirement rating is on the back of the microwave. If the operating power
requirement cannot be found on the back of the microwave, check the owner's
manual or contact the manufacturer.
Safety Precautions
For best results place the power inverter on a reasonably flat surface.
• Keep the inverter dry. Do not expose it to rain or moisture. Do not operate the
inverter if the device being operated or any other surfaces that may come in contact
with any power source are wet. Water and many other liquids can conduct electricity
which may lead to serious injury or death.
• Avoid placing the inverter on or near heating vents, radiators or other sources of
heat. Do not place the inverter in direct sunlight. Ideal air temperature should be
between 50°F and 80°F.
• In order to properly disperse heat generated while the inverter is in operation, keep
it well ventilated. While in use, maintain several inches of clearance around the top
and sides of the inverter.
• Do not use the inverter near flammable materials. Do not place the inverter in
areas such as battery compartments where fumes or gases may accumulate.
• When the inverter will be operating appliances with high continuous load ratings for
extended periods, it is not advisable to power the inverter with the same battery used
to power your car or truck. If the car or truck battery is utilized for an extended period,
it is possible that the battery voltage may be drained to the point where the battery
has insufficient reserve power to start the vehicle.
• It may be advisable to operate the inverter from a bank of batteries of the same
type in a "parallel" configuration. Two such batteries will generate twice the
amp\hours of a single battery; three batteries will generate three times the amp hours
and so on

PAGE 12
How Power Inverters Work
There are two stages in which a power inverter changes the 12 volt DC (or battery)
power into 220v AC (household current).
STAGE1:
The inverter uses a DC to DC converter to increase the DC input voltage from the
power source to 145 volts DC.
STAGE2:
The inverter then converts the high voltage DC into 220v AC (household current),
using advanced MOSFET transistor in a full bridge configuration. This design
provides all PowerBright inverters with the capability to start and run difficult reactive
loads, while providing excellent overload capability. The waveform that is generated
by this conversion is a "modified sine wave" as shown in the diagram below.
2300WATTPOWERINVERTERMODIFIED
The modified sine wave produced by PowerBright inverters has a root mean square
(RMS) voltage of 220 volts. The majority of AC voltmeters are calibrated for RMS
voltage and assumes that the measured waveform will be a pure sine wave.
Consequently, these meters will not read the RMS modified sine wave voltage
correctly and, when measuring the inverter output, the meters will read about 20 to 30
volts too low. To accurately measure of the output voltage of the inverter, use a true
RMS reading voltmeter such as a Fluke 87, Fluke 8060A, Beckman 4410, Triplett
4200 or any multimeter identified as "True RMS."

In Review
•Never attempt to operate this inverter from any power source other
than a 12 volt battery.
•Always disconnect the inverter when not in use.
•Always ensure the power cable terminal connections run Negative (-) to
Negative (-) and Positive (+) to Positive (+). Check these connections frequently
to make sure they remain secure. Use the heaviest gauge wire available to
connect the inverter to the power source. While connecting the inverter to the
power source, make certain that the inverter is positioned far away from any
potential source of flammable fumes or gases.
•Always ground the inverter before operating it. Make certain the power
consumption of the appliance or equipment you wish to operate is compatible
with the capacity of the inverter. Do not exceed 2300 watts. When attempting to
operate battery chargers, monitor the temperature of the battery charger for
approximately 10 minutes. If the battery charger becomes abnormally warm,
disconnect it from the inverter immediately.
•When operating the inverter with a battery that is connected to a vehicle, start the
engine every 30 to 60 minutes and let it run for approximately 20 minutes to
recharge the battery. In the event of a continuous audible alarm or automatic
shut down, turn the inverter OFF immediately. Do not restart the inverter until the
source of the problem has been identified and corrected.
•To avoid battery drain, always disconnect the inverter when not in use. Do not
expose the inverter to rain or moisture.
•Avoid placing the inverter near sources of heat or in direct sunlight.
•While in use, make sure the inverter is properly ventilated. Do not operate the
inverter near flammable materials, fumes or gases.

INTRODUCTION
Cet onduleur P{owerbright™ a été conçu pour vous offrir des années d’utilisation sûre et fiable.
Veuillez lire attentivement cette notice avant d’utiliser votre appareil afin de vous familiariser
avec ses caractéristiques et en optimiser les capacités. Conservez cette notice pour pouvoir
y référer au besoin.
À PROPOS DES ONDULEURS POWERBRIGHT™
Révolutionnant le domaine des onduleurs portatifs, PowerBright™ a créé une toute nouvelle
ligne d’onduleurs à haute performance. Le courant transitoire de crête développé par ses
onduleurs gérés par microprocesseur excède les capacités de la majorité des produits de
même type offerts dans l’industrie, tout en offrant une stabilité et une fiabilité accrues. Leur
puissance supérieure permet d’alimenter des appareils domestiques tels que téléviseur,
magnétoscope, four à micro-ondes, réfrigérateur et même de petites unités de climatisa-
tion! En atteignant la plus haute efficacité disponible (jusqu’à 90 %), ils maximisent la péri-
ode d’utilisation et la durée de vie de la batterie.
Ces onduleurs transforment le courant continu d’une batterie en courant alternatif de 220V.
Selon le modèle et la consommation de courant requise, les onduleurs peuvent être bran-
chés à la prise 12 V de votre voiture, camionnette, bateau ou véhicule récréatif ou directe-
ment à une batterie 12 V.

PAGE 19
UTILISATION DES ONDULEURS
Lorsque vous mettez en marche un appareil ou un outil fonctionnant avec un moteur ou des
tubes, une charge initiale est requise pour effectuer le démarrage. Cette charge de courant
est communément appelée « puissance de surtension » ou « puissance maximum ». Il est
important de déterminer la consommation de courant requise par les appareils que vous
souhaitez alimenter au démarrage et la charge nominale requise de façon continue.
La consommation de courant requise par un appareil est généralement indiquée en watts
ou en ampères sur la plupart des appareils. Si cette information n’est pas indiquée, vérifiez
la notice d’utilisation ou contactez le manufacturier pour vous assurer que votre appareil est
compatible avec une onde sinusoïdale modifiée.
Pour calculer la consommation de courant d’un appareil en watts,
utilisez l’équation suivante : Intensité de courant en ampères 220
(tension CA) = WATTS
Cette formule fournit la charge nominale continue approximative requise par l’appareil.
Pour déterminer la puissance de surtension approximative requise par
l’appareil que vous souhaitez alimenter, utilisez la formule suivante:
watts x 2 = puissance de surtension.
En général, le résultat obtenu par cette formule vous indiquera si votre onduleur est assez
puissant pour alimenter votre appareil. Pour déterminer si votre onduleur est assez puissant
pour alimenter un appareil en particulier, vous pouvez aussi effectuer un test. Les onduleurs
sont conçus pour s’éteindre automatiquement en cas de surcharge. Cette protection évite
de causer un dommage à l’onduleur en cas de surcharge.
Si un appareil de 2300 watts ne fonctionne pas correctement lorsque branché à un ondu-
leur, allumez, éteignez et rallumez rapidement l’onduleur. Si cette procédure se révèle
infructueuse, il y a de fortes chances que votre onduleur ne soit pas assez puissant pour
alimenter l’appareil en question.

UN ONDULEUR PLUS PUISSANT EST PEUT-ÊTRE REQUIS
Pour déterminer si votre onduleur est assez puissant pour alimenter un appareil en partic-
ulier, effectuez un test. Les onduleurs sont conçus pour s’éteindre automatiquement en
cas de surcharge. Cette protection évite de causer un dommage à l’onduleur en cas de
surcharge.
Si un appareil de 2300 watts ne fonctionne pas correctement lorsque branché à un ondu-
leur, allumez, éteignez et rallumez rapidement l’onduleur. Si cette procédure se révèle
infructueuse, il y a de fortes chances que votre onduleur ne soit pas assez puissant pour
alimenter l’appareil en question.
IMPORTANT
Votre onduleur est fabriqué pour opérer à partir d’une batterie 12V seulement. Ne tentez pas
de le connecter a d’autre sources de courant, incluant du courant AC. Ne modifier pas les
câbles de connexion de votre inverter. Un courant de 220V peut être mortel. Une utilisation
inadéquate peut provoquer des bris d’équipements, des blessures ou la mort.
