Troubleshooting
Problem
Inverter will not switch ON
Low voltage alarm on continuously or Low voltage
shutdown operating
Low voltage alarm on continuously or low voltage shutdown
operating with a 12V battery
Low voltage alarm on continuously or low voltage shutdown
operating with a battery bank
Low voltage alarm on continuously or low voltage shutdown
operating when using a battery being charged by a vehicle motor
Low output voltage reading
AC mains device causes inverter to go into overload shutdown
AC device runs hotter or more noisily than usual but otherwise
operates normally
AC device with built-in timer or clock is not keeping accurate time,
and programmed functions are not operating correctly
AC powerline network adaptor does not operate
RCD plugged into inverter does not operate normally
AC device operates abnormally
Video and/or audio interference when AV equipment is used
with inverter
10
Possible Cause
Low battery voltage
An incompatible AC device is connected
Inverter thermal shutdown activated
Poor DC connection
32V Fuse (17) blown
Inline fuse blown (if fitted)
High alternator voltage
Poor DC connection
Battery has reached the end of its service life and will no longer
hold enough charge
One or more batteries in a battery bank are faulty or at the end
of their service life
If the battery charge is already low and the vehicle electrical
system is under very high load the alternator may be unable to
provide sufficient power
Incorrectly measured with a multimeter or other voltage
measurement tool without a true RMS mode which will give a
low voltage reading
Device requires more continuous current or higher start-up current
than the inverter can supply
AC device not fully compatible
Device uses the AC waveform of the power supply to regulate
timer, and cannot work correctly with a modified sine wave inverter
Incompatible device
RCD is not compatible with inverter
Incompatible device
Inverter is 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
Solution
Charge or replace battery
Disconnect AC device
Allow inverter to cool before switching on
Check DC leads are suitable and undamaged. Replace if necessary.
Ensure connections are secure
Replace 32V Fuse
Replace inline fuse
Vehicle electrical system may have poor voltage regulation and
require repair
Check DC leads are suitable and undamaged. Replace if necessary.
Ensure connections are secure
Replace battery
Replace battery or batteries
Inverter current demands are too high for the vehicle's electrical
system. Reduce current demands or upgrade vehicle
electrical system
Measure with a true RMS multimeter or voltage measuring tool
If relevant reduce the number of devices connected to the inverter,
otherwise, the device is incompatible
Further use not recommended
Device incompatible
Use normal network cabling
DO NOT use with inverter
DO NOT use with inverter
Move inverter or aerial
Use fully shielded cable with correctly fitted connectors
AC equipment not compatible with inverter
Consult a vehicle electrician on how to suppress interference
