Operation
To operate the power inverter, turn it on using the
ON/OFF switch on the front panel. The power
inverter is now ready to deliver AC power to your
loads. If you are operating several loads from the
power inverter, turn them on separately after the
inverter has been turned on. This will ensure that
the power inverter does not have to deliver the
starting currents for all the loads at once.

！
The neutral (common) conductor of the power
inverter AC output circuit is connected to the
chassis ground. Therefore, when the chassis is
connected to ground, the neutral conductor will
also be grounded. This conforms to national
electrical code requirements that separately
derived AC sources (such as inverters and
generators) have their neutral tied to ground in
the same way that the neutral conductor from the
utility line is tied to ground at AC breaker panel.
Caution!
The negative DC input of the power inverter is
connected to the chassis. Do not install the
power inverter in a positive ground DC system.
A positive ground DC system has the positive
terminal of the battery connected to the chassis
of the vehicle or to the grounding point.
Warning!
Do not operate the power inverter without
connecting it to ground. Electrical shock hazard
may result.
Remote Control:
The ON/OFF switch turns the control circuit in the
power inverter on and off.
When the switch is in the OFF position, the power
inverter draws no current from battery. When the
switch is in the ON position but with no load, the
power inverter draws less than 600mA
(12V version) or 300 mA (24V version) from
battery.
1. Battery voltage indicator (under input voltage
mode)
The battery voltage displays the voltage
at the input terminals of the power inverter. At low
input current, this voltage is very close to the
battery voltage. At high input current, this voltage
will be lower than the battery voltage because of
the voltage drop across the cable and connections.
Ideally, the voltage should remain betwwen 11V to
16V. If the voltage goes down to 10.5V (for 12V
spec.) or 21.0V (for 24V spec.), inverter may
shutdown.
Troubleshooting
1.Common problems
a. Buzz in audio systems:
Some inexpensive stereo systems and "boom
boxes" will emit a buzzing noise from their
loud speakers when operated from the power
inverter. This is because the power supply in
the device does not adequately filter the modified
sine wave produced by the power inverter.
The only solution is to use a sound system that
incorporates a higher quality power supply.
b. Television interference:
Operation of the power inverter can interfere with
television reception on some channels. If this
situation occurs, the following steps may help to
alleviate the problem.
-Make sure that the chassis ground lug on the
back of the power inverter is solidly connected
to the ground system of your vehicle, boat or home.
-Do not operate high power loads with the power
inverter while watching television.
-Make sure that the antenna feeding your
television provides an adequate ("snow free")
signal and that you are using good quality cable
between the antenna and the television.
-Move the television as far away from the power
inverter as possible.
-Keep the cables between the battery and the
power inverter as short as possible and twist them
together with about 2 to 3 twists per foot. This
minimizes radiated interference from the cables.
2.Troubleshooting guide
Warranty
We offer 12 months warranty from the date of
purchase and will repair or replace any defective
power Inverter ,this limited warranty is void if the
unit is abused,modified,installed improperly,if the
housing has been removed,if the serial number is
missing,or if the original identification markings
have been defaced,altered,or removed.The
supplier is not liable for any incidental,
consequential or other damages arising from the
use,cost of removal,installation,or troubleshooting
of thw customer's electrical systems.

Repair or replacement are your sole remedies
and shall not be liable for damages, whether

Maintenance
Very little maintenance is required to keep your
inverter operating properly. You should clean
the exterior of the unit periodically to prevent
accumulation of dust and dirt. At the same time,
tighten the screws on the DC input terminals.

3. Grounding
The power inverter has a lug on the rear panel
"chassis ground". This is to connect the chassis
of the power inverter to the ground. The ground
terminals in the AC outlets on the front panel of
the inverter are also connected to the ground lug.
The chassis ground lug must be connected to a
grounding point, which will vary depending on
where the power inverter is installed. In a vehicle,
connect the chassis ground to the chassis of the
vehicle. In a boat, connect to the boat's grounding
systems. In a fixed location, connect the chassis
ground lug to earth.
2. Load indicator (under output power mode)
Displays the load watts in KW unit, i.e. if your load
spec. is 1200W, the display would show you
1.2(KW).
3. Overtemp indicator
The overtemp indicator indicates that the power
inverter has shut itself down, because it is
overheated. The power inverter may overheat
because it has been operated at power levels
above its rating, or because it has been installed
in a location where does not allow it to dissipate
heat properly.
Please turn on the inverter again when it cools
down.
4. Overload indicator (OLP)
The overload indicator indicates that the power
inverter has shut itself down because its output
circuit or drastically overloaded.
Turn off the inverter, correct the fault condition
or reduce load,then turn on the inverter and try
again.
Operating limits
1.Input voltage
The power inverter will operate from input voltage
ranging 10.5V-16V (12V spec.) or 21V - 32V
(24V spec). If the voltage drops below 10.5V
(12V spec.) or 21.0V (24V spec.), an audible low
battery warning will sound, and digital display
shows LVP.
The power inverter will also shut down if the input
voltages exceed 16V (12V spec.) or 32V (24V spec).
If the voltage are shut down because of high input
volt protection, an audibel high batterywarning
will sound, and display would shows HVP.
