INTRODUCTION
Congratulations on purchasing your new
Stanley ® 1000 Watt Power Inverter
instructions carefully before using your new inverter.
This power inverter is configured to supply continuous power in the form of two 120 volt AC outlets and a 5 volt USB charging
port to run most household or electronic appliances.

HOW THIS INVERTER WORKS

This inverter is an electronic device that converts low voltage DC (direct current) electricity from a battery to 120 volts AC
(alternating current) household power. It converts power in two stages. The first stage is a DC-to-DC conversion process that
raises the low voltage DC at the inverter input to 145 volts DC. The second stage is a MOSFET bridge stage that converts the
high voltage DC into 120 volts, 60 Hz AC.
Power Inverter Output Waveform
The AC output waveform of this inverter is known as a modified sine wave. It is a stepped waveform that has characteristics
similar to the sine wave shape of utility power. This type of waveform is suitable for most AC loads, including linear and
switching power supplies used in electronic equipment, transformers, and small motors.
CAUTION: Rechargeable Devices
• Certain rechargeable devices are designed to be charged by plugging them directly into an AC receptacle. These devices may
damage the inverter or the charging circuit.
• When using a rechargeable device, monitor its temperature for the initial ten minutes of use to determine if it produces
excessive heat.
• If excessive heat is produced, this indicates the device should not be used with this inverter.
• This problem does not occur with most of the battery-operated equipment. Most of these devices use a separate charger or
transformer that is plugged into an AC receptacle.
• The inverter is capable of running most chargers and transformers.
CAUTION – Incompatible Products: Certain products contain power supplies or circuits that are not compatible with a
inverter using a modified sine wave output (such as this inverter) and may be damaged by using this inverter.
If your product requires pure sine wave AC input power to function properly, the instruction manual for your product could
state this. If in doubt, you should contact your product manufacturer PRIOR TO USE.
Some products must be powered from a pure sine wave power source, such as standard household power, or a "pure sine
wave" inverter in order to function properly.
Your product could be damaged by this inverter if it contains:
• Microwave ovens;
• Transformerless battery chargers
• Capacitive coupled power supplies
If an incompatible product is used with this inverter:
• The product might not operate at all, with no indication of failure. The product fuse might open as a result of trying to use it
with the inverter.
• The product might exhibit unusual operation (such as, intermittent operation, buzzing, and the like.)
Note: Some laptop computers may not operate with this inverter.
WARNING: If the product does not operate normally, to reduce the risk of injury or property damage, turn the product
off immediately and unplug it from the inverter.

POWER SOURCE REQUIREMENTS

Your inverter will operate from input voltages between 11 and 15 volts DC. If the input voltage drops below 10 volts DC, the
inverter will shut down. This feature protects the battery from being completely discharged.
The inverter will also shut down if the input voltage exceeds 15.6 volts. This protects the inverter against excessive input
voltage. Although the inverter has built-in protection against over voltage, it may still be damaged if the input voltage exceeds
15 volts.
Your inverter is engineered to be connected directly to standard electrical and electronic equipment in the manner described in
the "Installation" section of this Instruction Manual. Do not connect the inverter to household or RV AC distribution wiring. Do

. Read this Instruction Manual and follow the

not connect the inverter to any AC load circuit in which the neutral conductor is connected to ground (earth) or to the negative
of the DC (battery) power source.
Inductive loads, such as TVs and stereos, require more current to operate than resistive loads of the same wattage rating.
Induction motors, as well as some TVs, may require two to six times their rated wattage to start up. Because these inverters
have a peak watt power rating, many such appliances and tools may be safely operated. The equipment that needs the highest
starting wattage are pumps and compressors that start under load. This equipment can be safely tested. If an overload is
detected, the inverter will simply shut down until the overload situation is corrected. Use the power button to turn off the
inverter, then on again to reset it.
CAUTIONS
• Exceeding recommended voltage limits will void manufacturer's warranty.
• NEVER try to use your inverter with any 12 volt DC power source that uses a positive ground. (Most vehicles and boats use
negative ground systems.)
• The Power Inverter must be connected only to batteries with a nominal output voltage of 12 volts. The unit will not operate
from a 6 volt battery and will sustain permanent damage if connected to a 24 volt battery.
• Reverse polarity connection will result in a blown fuse and may cause permanent damage to the inverter.
POWER AND FAULT INDICATORS ON THE LCD DISPLAY
Indicates that the unit is connected properly and functioning normally. The AC outlet
icon and USB icon will light solid and the Digital Readout shows the total output
wattage of AC outlets. The bars on the Battery Icon represent the voltage level of the
connected power source.
This indicates an input voltage too low fault condition. The fault icon and the empty
battery icon will light solid and the unit will emit three beeps every five seconds. Refer to
the following section for an explanation.
This indicates an input voltage too high fault condition. The fault icon and the full
battery icon will light solid and the unit will emit three beeps every five seconds. Refer to
the following section for an explanation.
This indicates a thermal fault condition. The fault icon and the overheat icon will light
solid and the bars on the Battery Icon represent the voltage level of the connected
power source. The unit will emit three beeps every five seconds. Refer to the following
section for an explanation.
This indicates a USB fault condition, and displays when the USB load exceeds capacity.
The USB icon will flash and the Digital Readout shows the total output wattage of AC
outlets. The fault icon and the AC outlet icon will light solid and the bars on the Battery
Icon represent the voltage level of the connected power source. The unit will emit three
beeps every five seconds.
This indicates an overload or short circuit fault condition. The AC outlet icon will flash
and the Digital Readout shows 0W. The fault icon and the USB icon will light solid and
the bars on the Battery Icon represent the voltage level of the connected power source.
The unit will emit three beeps every five seconds. Refer to the following section for an
explanation.
PROTECTIVE FEATURES AND FAULT CONDITIONS
The inverter monitors the following conditions:
Input Voltage Too Low: This condition is not harmful to the inverter, but could damage the power source, so the inverter will
automatically shut down when input voltage drops below 10.5 ± 0.5 volts DC.
Input Voltage Too High: The inverter will automatically shut down when DC input voltage exceeds 15.6 ± 0.5 volts, as this can
harm the unit.
Thermal Shutdown Protection: The inverter will automatically shut down when the unit becomes overheated.
Overload/Short Circuit Protection: The inverter will automatically shut down when an overload or short circuit occurs.
