 – The inverter is not functional.
 – The vehicle’s battery voltage is more than 15.5 volts. The inverter will
automatically restart after the voltage drops below 15.0 volts.

– The continuous load demand from the device exceeds the inverter’s
wattage output.

– The inverter is overheated and automatically turns off for a period of 1 to
3 minutes to cool. Make sure the inverter is well ventilated. It will automatically
restart after it cools.

– The vehicle’s battery voltage is less than 10.5 volts.
 – Short circuit, power surge or overload in the device.
IF THE INVERTER’S FUSE BLOWS
Your power inverter is fitted with a fuse, which should not have to be replaced
under normal operating conditions. A blown fuse is usually caused by reverse
polarity or a short circuit within the device or equipment being operated.
If the fuse does blow, take the inverter to a qualified technician for repair.
TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
Alarm is on. Display shows . Device
demands too much surge
power.
Device has a short circuit
Display shows . 12 volt
battery is too low.
Display shows voltage
between 10.5 and 11.0
volts.
Display shows . 12 volt
voltage is too high.
Cycle the inverter power OFF
and ON. If problem persists,
use a larger inverter or a
smaller device.
Remove the defective device.
Recharge/replace battery.
12V battery is low. Recharge or
replace battery. The inverter will
automatically shut off after battery
voltage reaches 10.5 volts.
If in a vehicle, repair/replace
the alternator or charging
system. Use a properly sized
and rated 12 volt battery. If
the input voltage returns to 15
volts or less, the inverter will
automatically restart.
