PROBLEM
POSSIBLE CAUSE
SOLUTION
The connected
device will not
operate.
The battery is defective.
Check the battery and replace it if required.
The power inverter is damaged
and needs to be repaired.
Have the power inverter repaired.
Incorrect cabling connections to the
power inverter.
Check connections. Make sure you turn the
connectors to the proper locking position.
The
power inverter
will run some
small loads, but
not larger ones.
The cables are either too long or not
heavy enough.
Use only the cables provided with your
power inverter.
Measured
power inverter
output is
too low.
The battery voltage is too low.
Recharge the battery.
Battery run
time is less
than expected.
The AC product power consumption
is higher than rated.
Use a larger battery to make up for the increase
in power requirement.
The battery is old or defective.
Replace the battery.
The battery is not being charged
properly.
Some chargers are not able to fully recharge
a battery. Make sure that you use a powerful
charger.
Power dissipation in DC cables.
Use only the cables provided with your
power inverter.
No power to
power inverter Blown fuse.
Replace fuse.
Buzz in audio
system.
Inadequate internal power supply
filtering of stereo system.
Use an audio system with a high-quality filter.
Television
interference.
TV signals are weak.
• Adjust the orientation of the power inverter,
television, antenna, and cable.
• Maximize TV signal strength by using a better
antenna, and use shielded antenna cable
where possible.
• Try a different TV model.
The digital display (D) shows error codes when the power inverter has shut down due
to the problems as shown in the following table:
PROTECTION
POSSIBLE CAUSE
SOLUTION
ERROR
CODE ON
DISPLAY
Low-
battery
alarm
As the battery discharges, its voltage
decreases. Voltage drops to: 10.5 –
11.0 V = alarm
Shut down sensitive loads such as
computers and then recharge the
battery.
Audible
alarm red
indicator
Low-
voltage
shutdown
Voltage drops to:
10.0 – 11.0 V = shutdown.
This protects the battery from being
over-discharged.
Recharge the battery.
Alarm red
indicator
High-
Voltage
shutdown
A defective battery charging system
can cause the battery voltage to rise
to high levels (15.0 – 16.3 V).
Although the power inverter has
a protection against high voltage, it
might still be damaged if the input
voltage were to exceed 16 volts.
Disconnect the connected devices.
Verify that the charging system is
properly regulated and the battery
is 12 V nominal.
Red
indicator
Overload
shutdown
If you connect a device that is
rated too high or a load that draws
excessive surge power, the
power inverter shuts down.
Use a product with a power rating
within the power inverter’s
continuous power rating (See
operating instructions).
Red
indicator
flash
Overheating
shutdown
The power inverter shuts down
automatically if it exceeds its safe
operating temperature.
Turn power inverter off and
allow it to cool for 15 minutes.
Disconnect it from the power
source.
Disconnect all connected devices.
Use a brush to clear any blocked
ventilation holes. Move the
power inverter to a cooler place.
Reduce load if continuous operation
is required.
