7. Common Problems and Simple Troubleshooting
If the Power Inverter does not appear to be functioning properly, check the following
possible causes.
1) Poor contact Ö Use a dry cloth to clean contact parts thoroughly. Check all
cable connections.
2) Receptacle has no power Ö Send it back to dealer where you bought it for
repair.
3) Battery voltage is too low Ö Start the engine to recharge the battery. Replace
battery if the battery is defective.
4) Shut down on overload Ö Reduce the wattage of your load.
5) Shut down on overload with high surge requirement devices Ö Try first
turning on the Power Inverter with all AC devices turning off. Then starting
to turn on AC devices each at a time, with the high surge AC device first.
6) Thermal shutdown Ö The Power Inverter will shut down to prevent damage
from excess heat under heavy loads for extended period of time. Simply
reduce your load and allow the Power Inverter to cool down.
7) Alarm is beeping Ö Alarm will be on when battery is low or the Power
Inverter is over heat (over temperature). Please recharge battery or turn off
the Power Inverter to cool down. Always keep the Power Inverter away from
heated sources and keep the ventilation openings in good condition.
8) Red light is on Ö Red light indicates the Power Inverter is in low voltage,
high voltage, overload, output short circuit or over temperature. Please follow
above instructions to provide appropriate remedy to the situation.
