7. Troubleshooting
7.1 Common problems
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 TV.
• 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 two to three twists per foot. This minimizes radiated
interference from the cables.
7.2 Troubleshooting Guide
Problem and Symptoms Possible Cause Solution
Inverter switched off.
No power to inverter
Turn inverter ON. Check wiring to
inverter.
Internal fuse open Have qualified service technician
check and replace.
No output voltage, no voltage
indication.
Reverse DC polarity Have qualified service technician
check and replace fuse, OBSERVE
CORRECT POLARITY.
No output voltage, Over Voltage
indicator on
High input voltage Make sure that inverter is
connected to 12 V or 24 V battery.
Check regulation of charging
system.
Low battery alarm on all the time. Poor DC wiring, poor
battery condition.
Use proper cable and make solid
connections. Use new battery.
Reduce load.
No output voltage and Under Voltage
indicator on
Low input voltage Recharge battery, check
connections and cable.
No output voltage, Over Temp
indicator on, load in excess of:
3000 W : 250 A (12V) or 125 A (24 V);
2000 W: 170A (12V) or 85A (24V);
1000 W: 90 A (12V) or 45 A (24 V);
600 W: 60 A (12 V) or 30 A (24 V).
Thermal shutdown Allow inverter to cool off. Reduce
load if continuous operation
required.
No output voltage, Over Temp
indicator on, load less than:
3000 W : 250 A (12V) or 125 A (24 V);
2000 W: 170 A (12V) or 85 A (24V);
1000 W: 90 A (12 V) or 45 A (24 V);
600 W: 60 A (12 V) or 30 A (24 V).
Thermal shutdown Improve ventilation, make sure
ventilation openings in inverter are
not obstructed, reduce ambient
temperature.
Short circuit or wiring
error.
Check AC wiring for short circuit or
improper polarity (hot and neutral
reversed).
No output voltage, Over Load indicator
on.
Very high power
load
Remove or reduce load
