TROUBLESHOOTING GUIDE
7.1 PROBLEM:
No output. LED is OFF. Buzzer is OFF
.
•
No power to the cigar lighter socket
•
Poor contact of cigar lighter plug
•
Fuse in the cigar lighter socket circuit is
blown
•
20A fuse inside the inverter is blown due to
reverse polarity or defect in the unit.
•
Turn the ignition to “ON” / “ACCESSORY”
•
Insert the plug firmly
•
Check to replace fuse
•
Replace the fuse. If blows again, the unit needs
to sent for repair.
7.2 PROBLEM:
Output voltage is low. LED is GREEN.
Buzzer is OFF
REASON
POSSIBLE REMEDY
•
Output voltage pulses clipped due to
overload or short circuit in output
•
Reduce load/ Remove short
7.3 PROBLEM:
No output. LED is ORANGE. Buzzer is ON
•
Low battery shut-down due to discharged
battery or excessive voltage drop in the
cabling from the battery to the cigar ligher
socket
•
Over temperature shut down.
•
Re-charge the battery
Ensure cable from battery to cigar lighter socket
is thick enough to carry 15A
Ensure contact between the cigar lighter plug
and the socket is firm
•
Switch off the unit to cool down.
Improve ventiliation.
Reduce load.
7.4 PROBLEM:
No output. LED is ORANGE. Buzzer is OFF
Shut down due to input voltage beyond 15V. (
CAUTION!
This may
permantly damgae the inverter.)
•
Inverter wrongly connected to 24V Battery
instead of 12V Battery.
•
Charging alternator’s voltage has been set
beyond 15V, or it’s regulator has become
defective.
•
Batteries are being charged simultaneously
from an unregulated solar panel set beyond
15V
•
Batteries are connected to a battery charger
with its boost voltage set beyond 15V
•
Ensure battery is 12V
•
Set the voltage correctly or repair the alternator
•
Ensure that the voltage of solar panel does not
exceed 15V
•
Ensure that the boost voltage of the battery
charger is less than 15V
7.5 PROBLEM:
No output when load is switched on. LED is GREEN
•
The starting current required by the load is
higher than the surge rating of 300 watts
•
Use inverter with appropriate surge rating.
7.6 PROBLEM:
There is no output when the vehicles engine is cranked.
•
On cranking, the battery voltage drops
below 10V
•
Switch OFF the inverter when cranking the
engine.
