THE SELF PROTECTION OF YOUR INVERTER
Type Possible cause
How do you know
if the protection is
activated?
Solution Remarks
Current
overload
If the output
power exceeds
the rated output
power 10 to 15%.
Fault indicator LED
will light up and the
inverter will
automatically shut off
Remove all appliances and
turn off the unit by the
ON/OFF switch. Then turn on
the unit again. Use smaller
power consumption
appliances.
Input low
voltage
Input voltage
lower than 10.5V.
Remove all appliances and
turn off the unit by the
ON/OFF switch. Recharge
the battery.
Input high
voltage
Input voltage
higher than 15V.
Remove all appliances and
turn off the unit by the
ON/OFF switch. Check the
battery voltage, make sure it
is within 11V to 15V.
Although the inverter has
protection against over
load, it may still damage
the inverter if the input
voltage exceeds 16V.
Over
temperature
The PCB
temperature is
around 230°F.
Remove all appliances and
turn off the unit by the
ON/OFF switch. Cool down
for 15 minutes before turning
on again.
Please ensure there is
ventilation in the
surrounding environment.

BATTERY OPERATING TIME
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 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.
Because the power inverter draws less than 0.5A with it turned on and with
no AC product connected, it has minimal impact on battery operating times.
INTERFERENCE WITH ELECTRONIC EQUIPMENT
Generally, AC products operate with the inverter just as they would with
household 110V/AC power. Below is the information concerning two
possible exceptions.
BUZZING AND IN-AUDIO SYSTEMS AND RADIOS
Some stereo systems and AM/FM radios have inadequate internal power
supply filtering and “buzz” slightly when powered by the inverter. Generally,
the only solution is an audio product with a higher quality filter.
TELEVISION INTERFERENCE
The inverter is shielded to minimize its interference with TV signals.
However, with weak TV signals interference may be visible in the form of
lines scrolling across the screen.
The following should minimize or eliminate the problem:
• Increase the distance between the inverter and the TV, antenna and
cables.
• Adjust the orientation of the inverter, TV, antenna and cables.
• Maximize TV signal strength by using a better antenna and use shielded
antenna cables where possible.

TROUBLESHOOTING
Problem Cause Solution
No power, no
indicator
Battery is defective. Replace battery.
Blown fuse. Check and replace fuse.
Loose cable connections. Check the connection to the
battery. Tighten as required.
The red LED
indicator
illuminates
The actual output is higher
than rated power of inverter,
Overload protection has
occurred.
Reduce load to have the
actual output lower than
rated power of inverter.
The actual output is less
than rated power, but high
starting surge has caused
overload shutdown.
Use a product with starting
surge power within the
inverter’s capability.
The voltage input is too low. Charge the battery.
Inverter is overheated due to
poor ventilation and has shut
down.
Disconnect the inverter from
battery or DC socket and
allow to be cooled for 15
minutes. Please ensure to
remove objects covering
the unit.

Problem Cause Solution
Inverter runs
small loads
but not large
loads.
Low voltage battery. Charge the battery.
Water entered. Water entered the unit. Disconnect the inverter and
wipe immediately with a dry
cloth, or permanent damage
can occur from the liquid.
Measured
inverter output
is too low
Standard “average-reading”
AC voltmeter used to
measure output voltage,
resulting in an apparent
reading 5V to 15V too low.
Inverter’s “modified sine
wave” output requires “true
RMS” voltmeter for accurate
measurements.
Battery voltage is too low. Recharge battery.
Battery run
time is less
than expected.
AC product power
consumption is higher than
rated.
Use a larger battery to make
up for increased power
requirement.
Battery is old or defective. Replace battery.
Battery is not being properly
charged.
Some chargers are not
able to fully recharge a
battery. Make sure you use a
powerful charger.
Power dissipation in DC
cables.
Use shorter/heavier DC
cables.
