Description

7.
Safe
Do not operate the unit in the same compartment as batteries
or in any compartment capable of storing flammable liquids
like gasoline.
Clean Do not operate the unit in an area that is prone to dirt, dust or
debris. Especially important if used in a work environment.
Your 1500W Power Inverter supplies 1500 watts of max continuous power
with 3000 watts of surge power. When you turn on an appliance or a tool that
operates using a motor or tubes, 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 and its continued running power requirements.
The inverter should be connected to your vehicle’s 12 V power supply with
the DC cables. We recommend that the equipment or appliance switch be in
the “OFF” position prior to plugging into the AC receptacle of the inverter.
Warning！
Shock hazard! Keep away from children!
Please be sure to put off some metal jewelry, such as rings, bracelets and
watches etc. in case any accident would happen!
Connecting the inverter:
1) Place the inverter on a flat surface, such as on the vehicle floor.
Cool Ambient air temperature should be between 32°F and104°F
(0°C~40°C)（the cooler the better within this range）.
Ventilated Leave at least 2” (5cm) of clearance around the unit for airflow.
Ensure that the ventilation openings are not obstructed.

6. Operating Instructions
2) Please make sure that the inverter is shut down.
3) Attach the ring type connector marked with red to the positive (+) DC
terminal on the power inverter, and attach the ring connector marked
with black to the negative (-) DC terminal.
Caution！
Reversing the polarity will cause a blown fuse or damage to the inverter,
which may also void the warranty.
Caution！
A loose connection will cause the voltage to drop and may cause the cables to
overheat, resulting in equipment damage or fire.
Caution！
If there are one more AC products connecting to the inverter, turn on
the larger power product first.
4) Tighten the nut on each DC terminal by hand until it is snug. Do not
over-tighten.
5) Connect the AC equipment.
6) When the power inverter is not in use, disconnect the DC cable clips
from the battery to prevent gradual discharge of battery.
Note: This product does not include DC battery cables. DC battery cables
sold separately.
1) When properly connected to a 12 V outlet or battery, turn on the
inverter, and the digital readout will switch on and the unit will deliver
AC power to the outlet(s).
2) Plug the AC product(s) you wish to operate into the AC outlet(s)
3) Switch them on, one at a time.

9.
Caution！
Most vehicle batteries are designed to provide short period of very high
current for starting the engine. They are not designed for a constant “deep
discharge”. Constantly operating the unit from a vehicle battery until the low
voltage shut off will affect the life of the battery. If you are operating electrical
products for extended periods of time, you should consider connecting the
unit to a separate deep discharge battery.
Should a defective battery charging system cause the battery voltage to rise
to the range of 15.0V~16.0VDC, the inverter automatically shuts down; and
the red LED lights.
Caution！
Although the inverter incorporates protection against over-voltage, it
may still be damaged if the input voltage exceeds 16 volts.
If an AC product rated higher than 1500W (or which draws excessive surge
power) is connected, the inverter will shut down. The red LED light will light.
The unit will shut down automatically if the inverter exceeds a safe operating
temperature due to insufficient ventilation or a high-temperature environment;
and the red LED indicator lights.
The cooling fan is designed with thermo-controlled technology.
4) The unit will operate from input voltages ranging from 11.0 V to 14.0 V
DC.
As the battery is used, its voltage begins to fall. When the inverter senses
that the voltage at its DC input has dropped to the range of 10.7~11.3V DC,
an audible alarm sounds. This allows time for computers or other sensitive
devices to be shut down. If the audible alarm is ignored, the inverter will
automatically shut down when the voltage dropped to the range of
10.2~10.8V DC. The red LED indicator illuminates, indicating a fault. This
protects the battery from being over-discharged. Turn off any devices that the
inverter is powering.
When input voltage rose to 11.7V~12.3V DC, inverter restores normal.

10.
Caution！
Operating time will vary depending on the charge level of the battery, its
capacity and the power level drawn by the particular AC load. With a typical
vehicle battery and a 1500-watt load, an operating time of 1 hour or more can
be expected.
When using a vehicle battery as a power source, it is strongly recommended to
start the vehicle every hour to recharge the battery before its capacity drops too
low. The inverter can operate while the engine is running, but the normal
voltage drop that occurs during starting of the engine may trigger the inverter’s
low voltage shutdown feature.
Caution！
Because the power inverter draws less than 0.8A with its turning on and with no
AC product connected, it has minimal impact on battery operating times.
