Problem
Possible cause
Solution
Engine will not start with jump
starter connected
Vehicle battery at very low charge level
Vehicle battery will require charging with a suitable battery charger
Jump starter battery not fully charged
Ensure jump starter is regularly charged to ensure always ready for use
Jump starter below the required capacity for engine
type and capacity
Jump starter suitable for petrol engines up to 2800cc and diesel engines up to
2200cc. These capacities are approximate and based on a reasonable level of
existing charge in the vehicle’s battery
Vehicle battery faulty
Replace vehicle battery
After disconnecting jump starter
and running the engine for several
minutes the vehicle will not
start again
Insufficient charge in vehicle battery
Follow jump starter procedure again to increase time of vehicle
battery charging
Alternator not providing battery charging current
Vehicle alternator requires maintenance/repair
Vehicle battery faulty
Replace vehicle battery
AC device will not operate
with inverter
Incompatible AC device is connected
Disconnect AC device
Current or starting current requirements of AC device
are too high
AC device not compatible
Inductive load AC device not compatible with modified
sine wave AC
Try connecting a low-power resistive load device, like a small
filament lamp, at the same time. This may cause the inductive load device
to function
AC device runs hot or is
more noisy than normal but
operates satisfactorily
AC device not fully compatible with modified sine
wave AC
It is recommended not to use the AC device
AC device with a built-in timer or
clock is not keeping accurate time
so its functions are not correctly
timed
If the device uses the AC waveform to regulate its timer
rather than a crystal oscillator it will not work correctly
with a modified sine wave inverter
Device is not fully compatible
Compressor function abnormal,
or compressor not working
Compressor used beyond 5 minutes
Operate for a maximum of 5 minutes only and allow 5 minutes to cool
before reusing
