TROUBLESHOOTING
If the inverter does not appear to be functioning properly, there are several causes why the
inverter may not be responding.
1. Poor contact
Clean the contact parts thoroughly.
2. Receptacle has no power
Check car fuse, replace damaged fuse.
Check receptacle wiring, repair if necessary.
3. Fuse is blown
The fuse is located inside the DC plug. Replace fuse with a fuse of equivalent value.
4. Overload cause AC output shutdown
Reduce the wattage of your load to lower than 300 watts.
5. Thermal caused AC output shutdown
Under heavy loads for extended periods of time the AC inverter will shutdown output to
prevent damage to excess heat. If this happens, please proceed as below:
a. Switch off the power switch of this converter.
b. Decrease load of this machine i.e. disconnect some of the appliances or wait until this
inverter becomes cool.
c. Switch on the power switch of this inverter.
6. Low-battery shutdown
Recharge your battery and resume operation.
CAUTION
Always place the inverter in an environment which is:
A. Well ventilated
B. Not exposed to direct sunlight or heat source
C. Out of reach from children
D. Away from water/moisture, oil or grease
E. Away from any inflammable substance
IMPORTANT: When connected to any appliance, be sure to turn on inverter first, and then,
turn on the power switch of the appliance.
CAUTION: do not reverse input. First use red battery cord to connect the (+) of a 12V DC
battery to the (+) terminal, and then use the black battery cord to connect the (-) of a 12V
DC battery to the (-) terminal.
When, during operation, with the power switch turned on, the indicator light is not working,
please check the fuse in the battery cord and cigarette plug. If the fuse is spoilt, replace it with
the same current fuse.
If the total watt of electrical appliance exceeds the output capacity of the inverter, or if the
temperature of the inverter reaches 60ºC after operating for a period of time, the inverter shall
be shutdown by the protection circuit.
Wisdom fan start: when the output reached 100W or the temperature reaches over 45°C, the
fan will start automatically.
Problems like output shortage, overload or over temperature can be identified and resolved by
looking at the spark speed of the LED's.
Low voltage input: Red LED stays bright
Overtemperature:
Red LED sparks fast
Overload:
Red LED sparks slowly
