Welcome
Please read this manual thoroughly before installing and operating your
new Energizer®Power Inverter. This manual contains information you
need to obtain the performance required for your application. Keep this
manual for future reference.
This Energizer®Inverter converts low voltage, direct current (DC) to 110
volt modified sine wave (MSW) alternating current (AC). The inverter
draws power from 12 volt, deep-cycle batteries such as those used for
marine, golf cart, and fork-lift or from other high current 12 volt sources.
This model, EN900 / EN1100, has been performance tested by MET and
complies with Underwriter’s Laboratories and Canadian Standards
Association safety standards.
A Higher Wattage Inverter May Be Required
To determine whether the Energizer®EN900 / EN1100 will operate a
particular appliance or a combination of appliances, 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 with combined wattages in the 900 / 1100 watt range.
Turn on the highest wattage appliance first then other appliances. If an
appliance combination in the 900 / 1100 watt range will not operate
properly, then it is likely that this Energizer® inverter does not have the
required capacity to operate the appliance in question.
WARNINGS, CAUTIONS AND NOTES
It is very important that any operator and installer of this inverter read
and follow all WARNINGS, CAUTIONS AND NOTES and all installation
and operation instructions. In particular, comply with WARNINGS
(possibility of serious injury or death), CAUTIONS (possibility of damage
to the inverter and / or other equipment), and NOTES (included to assist
you in achieving the maximum performance and longest working life from
this advanced-design inverter).

WARNINGS: INVERTER OUTPUT
This is a heavy-duty device that produces voltages similar to commercial
AC power.
•Danger of shock or electrocution - treat inverter output the same as
commercial AC power.
•Do not use the inverter near flammable materials or in any locations
that may accumulate flammable fumes or gases. This is an electrical
device that can briefly spark when electrical connections are made or
broken.
•Do not allow water or other liquids to contact the inverter.
•Do not use appliances with damaged or wet cords.
CAUTIONS: INVERTER OPERATING ENVIRONMENT
•Surrounding air temperature should be between -20°C and 40°C –
ideally between 15°C and 25°C (60 - 80°F).
•Keep the inverter away from direct sunlight if at all possible.
•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. The unit will shut down if the internal temperature
gets too hot. Restart the inverter after it cools.
•This Energizer®inverter will only operate from a 12V power source.
Do not attempt to connect the inverter to any other power source,
including any AC power source.
•Do not reverse DC input polarity – this will void the warranty.
APPLIANCE CAUTIONS
•Do NOT plug in battery chargers for cordless power tools if the
charger carries a warning that dangerous voltages are present at the
battery terminals.
•Certain chargers for small nickel-cadmium or nickel-metal-hydride
batteries can be damaged if powered by this inverter. Two types of
appliances are susceptible to damage: Small, battery-operated
appliances such as flashlights, cordless razors and toothbrushes that
plug directly into an AC receptacle.
•Do NOT use this inverter with the above two types of equipment.
•The majority of portable appliances do not have this problem. Most
portable appliances use separate transformers or chargers that plug
into AC receptacles to supply a low-voltage DC or AC output to the

4
appliance. If the appliance label states that the charger or adapter
produces a low-voltage DC or AC output (30 volts or less), there will
be no problem powering that charger or adapter.
•Some fans with synchronous motors may slightly increase in speed
(RPM) when powered by the inverter. This is not harmful to the fan
or to the inverter.
•Route appliance cords and extension cords to prevent accidental
pinching, crushing, abrading and tripping people.
•Use safety approved extension cords rated at 15 amps or higher.
•GFCI devices may not work with modified sine wave (MSW) power.
•This inverter is not tested for use with medical equipment.
•This inverter is not tested for use in marine applications.
•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.
•When attempting to power lead acid battery chargers, with modified
sine wave, monitor the temperature of the battery charger for
approximately 10 minutes. If the battery charger becomes
abnormally warm, immediately disconnect it from the inverter.
Getting Started
When a motorized appliance or a tool turns on, there is an initial surge of
power to start. This surge of power is referred to as the "starting load" or
"peak load." Once started, the tool or appliance requires less power 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 its continued running
power requirements (continuous load).
Power consumption is rated in watts, or it can be calculated from
amperes (amps). 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. For electrically
sensitive equipment, contact the manufacturer to determine if the device
you are using is compatible with modified sine wave AC.

5
Multiply: AC AMPS X 110 (AC voltage) = WATTS
This formula yields a close approximation of the continuous load of your
appliance.
Multiply: WATTS X 2= Starting Load for most appliances
This formula yields a close approximation of the starting load of most
appliances. Exceptions are motorized appliances such as pumps,
freezers and air conditioners. These appliances can have startup loads
of up to eight times the rated watts.

Determining the DC Power Requirements
Powering multiple appliances from the high-power EN900 / EN1100
inverter requires a 12 volt bank of batteries (several batteries). To
calculate the approximate power in amps a 12 volt battery bank has to
supply you need to know the current, or amps required for powering the
continuous AC load.
A shortcut method is to divide the continuous AC load wattage by 10. For
example, the continuous AC load is 900 watts. The current (amps) is:
900/10 or 90 amps at 12 VDC. Add to the load any DC appliances that
may be powered by the battery bank.

8
Sizing the Battery Bank
To determine the minimum battery bank 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:
1. List the maximum wattage that the inverter has to provide (as
above).
2. Estimate the number of hours the appliances will be in use
between battery recharges. This will differ depending on
appliances. As an example, a typical home-use coffeemaker
draws 500 watts during its brew time of 5 minutes; it maintains
the temperature of the pot at about 100 watts. Typical use of a
microwave oven is only for a few minutes. Some longer
operating time appliances are lamps, TVs, computers and
refrigerator / freezers.
3. Determine the total watt-hours of energy needed. Then multiply
the average power consumption in watts by the number of
hours of run time. For example: 900 watts for 10 hours = 9,000
watt hours. Using the 900 watts (or 90 Amps) for 10 hours
example as above, then 90 amps is needed for 10 hours. This
provides us with the basic amp-hours (AH) of battery that is
required. Ten hours at 90 amps equals 900 Amp Hours (AH).
This answer is just a beginning because there are other
conditions that determine actual run time. These include:
• AC appliance load and time in use (basic Amp Hour)
• 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
capacity/amp hours)
• Compliance with turning off unnecessary AC and DC loads.
If there is any doubt about sizing the battery bank, it is safe to
over estimate the amp hour requirements of the battery bank.

Note:
The type of batteries you use to power your high power inverter is
important. Operating a high-power inverter will routinely discharge
batteries and they will require frequent recharging. Batteries used to start
engines are not designed to repeatedly charge and discharge.
Energizer®recommends using “deep-cycle” or “marine” rated batteries.
Cable Gauges
When connecting the inverter to a battery bank use the thickest stranded
insulated copper wire available, in the shortest length practical.
Recommended cable gauges are as follows:
WARNING:
DANGER OF BATTERY EXPLOSION – INSTALL A FUSE
Battery banks can deliver very high levels of current that can vaporize
metal, start fires and cause explosions. Energizer®recommends
installing one ANL type fuse and fuse holder close to the positive battery
bank terminal. This fuse protects the batteries from accidental DC cable
shorts, which can cause batteries to explode. ANL fuses and fuse
holders are available at most marine supply stores.
CAUTIONS:
• Loose connections can result in a severe decrease in voltage that
can cause damage to cables and insulation.
• Failure to make correct polarity ( Pos, Neg ) connection between the
inverter and the battery bank can result in blowing fuses in the
inverter and can permanently damage the inverter. Damage caused
by reversed polarity is not covered under the Energizer® warranty.

• Making the connection to the Positive terminal may cause a spark as
a result of current flowing to charge capacitors within the inverter.
This is a normal occurrence.
• Because of 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.
• Operating the inverter without correctly grounding the unit may result
in electrical shock.
Mounting the Inverter
Your Energizer®Inverter should not be mounted under the hood of a
vehicle.
If installing in a vehicle, choose a dry, cool, ventilated area closest to the
battery as practical. Before drilling any mounting holes, make sure that
there are no wires, fuel lines, or tanks directly behind the surface to be
drilled. To mount the inverter:
1. Inverter must be OFF.
2. The inverter should be mounted horizontally.
3. Position the inverter against the mounting surface and mark
locations of the mounting screw openings.
4. Remove the inverter and drill four mounting holes.
5. Fasten the inverter to the mounting surface using corrosion-resistant
fasteners sized #10 or larger.
Connecting the Inverter
This inverter has two DC cable connections, one positive and one
negative. The order of steps in the following procedure minimizes the
danger of sparking near the battery bank.
1. Prepare all cable set ends with ring terminals at the battery ends.
2. Install one fuse holder with fuse in the Pos cable close to the battery
bank end.
3. Make sure the inverter is OFF.
4. Ensure all appliance cords or extension cords are disconnected from
the inverter.
5. Connect an appropriate stranded insulated wire to the enclosure
ground terminal and connect the free end of the wire to the vehicle’s

11
chassis or any other ground point.
6. Connect the un-fused cable to the Negative (-) terminal of the battery
bank.
7. Connect the Negative cable to the Inverter’s Negative (-) terminal.
8. Insulate the end of cable to be connected to the Pos (+) Inverter
terminal.
9. Connect the fused cable to the battery bank Pos (+) terminal.
10. Connect the Pos cable end to the Pos (+) inverter terminal.
NOTE: Sparking is normal for the first connection.
Make sure you have good secure connections – Do not over-tighten.
Operation
1. Turn On the inverter.
2. Turn OFF the inverter.
3. When you have confirmed that the appliance to be operated is
turned off, plug an appliance cord into one of the two 110v AC
Outlets on the front panel of the inverter.
4. Turn ON the inverter.
5. Turn the appliance on.
6. Plug in additional appliances and turn them on.
Note:
The audible alarm may make a momentary "chirp" when the inverter is
turned OFF. This same alarm may also sound when the inverter is being
connected to or disconnected from the 12 volt battery bank.
Television and Audio Suggestions
Although all Energizer®inverters are shielded and filtered to minimize
signal interference, some interference with your television picture may be
unavoidable, especially in weak signal areas.
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 TV power
cord.
3. Isolate the TV, its power cord and antenna cables from the 12 volt

12
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 produce a slight "buzzing" sound
when operated with the inverter. The only solution to this problem is to
use a sound system with better power supply filtering.
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 rating is listed on the back of the microwave. If
the operating power cannot be found on the back of the microwave,
check the owner's manual or contact the manufacturer.
How This Modified Sine Wave Power Inverter Works
There are two stages in which this power inverter changes the 12 volt
DC (or battery) power into 110v AC (household current).
STAGE 1: This inverter uses a DC to DC converter to increase the DC
input voltage from the battery to 145 volts DC.
STAGE 2: The inverter then converts the high voltage DC into 110v AC
(household current), using advanced MOSFET transistor in a full bridge
configuration. This design provides this Energizer®inverter 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.

13
Best use of Battery Power
Make sure any appliances are energy efficient and turned off after use.
Use Compact Florescent Lamps. Wherever possible, charge with Solar
Panels or Wind Generators. Do not allow lead acid batteries to remain
discharged for long periods of time, they lose capacity (amp hours).
Disposal / Recycling of Inverter / California Proposition 65
Electronic products are known to contain materials that are toxic if
improperly disposed. Contact local authorities for disposal and recycling
information.
This inverter is certified to be “lead free.” Transformers in this inverter
contain nickel composites. Nickel is a known neuro-toxin if ingested.
