7.0 Troubleshooting
7.1 Television interference
Operation of the inverter can interfere with television reception on some
channels. If this situation occurs, the following steps may help to alleviate the
problem.
 Ensure that the chassis ground lug on the back of the inverter is
securely connected to the ground system of your vehicle, boat, or home.
 Do not operate high power loads with the inverter while watching
television.
 Make sure that 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 TV.
 Move the television as far away from the inverter as possible.
 Keep the cables between the battery and the inverter as short as
possible and twist them together with about 2 to 3 twists per foot. This
minimizes radiated interference from the cables.

No output voltage, red
LED blinking fast High input
voltage
Ensure that inverter is
connected to a 12 V / 24 V
battery. Check the regulation
of charging system.
No output voltage, red
LED blinking slowly
Poor DC wiring,
poor battery
condition Use the proper cable and
make secure connections.
Use a new battery.
No output voltage, load in
excess of 150 W, red LED
blinking intermittently
Thermal
shutdown
Allow the inverter to cool off.
Reduce the load if continuous
operation required.
No output voltage, load
less than 150 W, red LED
blinking intermittently
Thermal
shutdown
Improve ventilation; ensure
that the inverter ventilation
openings are not obstructed.
Reduce the ambient
temperature.
No output voltage, red
LED solid
Overload Reduce the load.
