Adding an Extension Cord
If you need an extension cord, we recommend the use of an extension cord
between the AC output of the inverter and AC appliances. You may use up to
100 feet of a high quality extension cord. A long cord will result in reduced
output power.
Buzz in Audio Systems
Some stereo systems will emit a buzzing noise from their loudspeakers when
operated from the power inverter 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.
Operating a Television
Picture tubes have a degaussing coil that uses a high initial surge of power
to light up the screen from a “cold start.” If the television does not start up on
the first try, switch on the TV every 2 to 3 seconds until the screen comes on.
Sometimes it may take 2 to 5 tries before starting.
Television Interference
Operating the power inverter can interfere with television reception on some
channels. If this situation occurs, the following steps may help to alleviate the
problem:
1. Make sure the chassis ground lug on the back of the power inverter is
solidly connected to the ground system of the vehicle.
2. Do not operate high power loads with the power inverter while watching
television.
3. Make sure the antenna feeding your television provides an adequate,
“snow free” signal and that you are using a good quality cable between
the antenna and the television.
4. Move the television as far away from the power inverter as possible.
5. 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 the radiated interference from the cables.
TROUBLESHOOTING
Problem: AC product does not operate, green light does not light
Probable Cause
Suggested Remedy
AC product connected is rated at
more than 700 watts; overload
shutdown occurs.
Use product with a power rating of
less than 700 watts.
High starting surge has caused
overload shutdown even though AC
product connected is rated at less
than 700 watts.
Product exceeds inverter’s surge
capability. Use a product with
starting surge power of less than
1800 watts.
Lighter socket or 12 volt outlet may
require ignition to be switched on.
Turn ignition key to accessory
position.
Poor contact with lighter socket or 12
volt outlet.
Press inverter firmly into the lighter
socket. Make sure the socket is
clean.
Battery is discharged.
Recharge battery.
Fuse blown by heavy load.
Replace the 30A slow blow fuse by
unscrewing the fitting in the positive
connector.
Problem: Buzzing sound in audio systems
Inexpensive stereo systems have an inadequate internal power supply filtering
which causes a buzzing sound. A system with a high quality filter is the only
solution.
