Troubleshooting
Problem
Inverter will not switch on
Low voltage alarm on continuously or
Low voltage shutdown operating
Low output voltage
AC mains device causes inverter to
go into overload shutdowntrekker
schakelaar wordt ingeknepen
AC mains device will not start but
inverter does not go into overload
shutdown
AC device runs hot or is more
noisy than normal but operates
satisfactorily
AC device with a built-in timer or
clock is not keeping accurate time so
its functions are not correctly timed
AC power line network adapter does
not operate
RCD plugged into inverter does not
operate normally
AC device abnormal operation
AC device instructions gives warning
about not using with inverters
Video and/or audio interference when
AV equipment is used with inverter
Cause
Low battery voltage
An incompatible AC device is connected
Inverter in thermal shutdown
DC cables are poorly connected
Internal fuses 'blown' possibly due to short circuit
Inline fuse blown if fitted
High alternator voltage
One or more batteries in a battery bank is faulty or end of
service life
DC cables are inadequate or poorly connected
Vehicle electrical system is under very high load with battery
at low charge and alternator is not able to charge both battery
and provide adequate power to inverter
Low capacity battery that is only capable of handling high
current demands from the inverter for a short time before
a voltage drop
Incorrectly measured with a multimeter or other voltage
measurement tool without a true RMS mode which will give a
low voltage reading
Device requires either too much current continuously or has
too high starting current requirements
Insufficient DC power. Battery or batteries simply not capable
of delivering the required level of current
Inductive load AC device not compatible with modified sine
wave AC
AC device not fully compatible with modified sine wave AC
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
These devices do not normally work correctly with a modified
sine wave AC waveform
RCD is not compatible with inverter
Incompatible with modified sine wave AC output
This indicates the device is not compatible with a modified
sine wave inverter and may be damaged by doing so
Inverter is used too close to aerial
Aerial cable not shielded or insufficiently shielded
AV equipment not operating correctly with modified sine
wave output
AV equipment picking up interference from vehicle ignition
Charge or replace battery
Disconnect AC device
Allow inverter to cool before switching on
Check DC leads for damage and secure connections
Have inverter serviced at an authorised service centre
Vehicle electrical system may have poor voltage regulation and require repair
Replace battery or batteries
Recheck cables are suitable and correctly connected
Inverter current demands are too high for the vehicle's electrical system. Reduce
current demands or upgrade vehicle electrical system
Replace battery with higher capacity model or if possible a deep cycle (leisure) or
traction battery which are more suitable for inverters
Measure with a true RMS multimeter or voltage measuring tool
Device not compatible with inverter or you have overloaded inverter with too many
Calculate the required DC current and check the DC current available is sufficient
Try pairing with a low power resistive load device like a small filament lamp
AC device not compatible
It is recommended not to use the device
Device is not fully compatible
Use normal network cabling which is also a more efficient use of power
DO NOT use with inverter
DO NOT use with inverter
DO NOT use with inverter
Move inverter or aerial
Use fully shielded cable with correctly fitted connectors
AV equipment not compatible with inverter
Consult a vehicle electrician on how to suppress interference
