Adjust the orientation of the inverter, television, antenna and cables. Maximize TV signal strength by using a better
antenna and use shielded antenna cable where possible.
Try a different TV. Different models of televisions vary considerably in
Their susceptibility to interference.
7. Troubleshooting
If you have any problem with your inverter, the first thing you should do is to disconnect any load
from it, switch the inverter off and disconnect it from the battery. The summary table below
should help you to find the cause of the problem.
Possible Cause
Suggested Remedy
PROBLEM: AC product will not operate, no inverter lights are ON.
Battery is defective.
Check battery and replace if required.
Inverter has been connected with reverse
DC input polarity.
Check connection to battery. Probable inverter damage has
occurred., Have unit repaired (not covered by warranty).
Loose cable connections
Check cables and connections.
Tighten as required.
PROBLEM: Inverter will run some small loads, but not larger ones.
Voltage drop across DC cables.
Reduce the cable and use bolder one
PROBLEM: Measured inverter output is too low.
Standard average-reading AC voltmeter
used to measure output voltage, resulting
in an apparent reading below 100V or
200V AC.
Inverter's 'pure sine wave' Output Requires 'true RMS'
voltmeter, such as Fluke 87 series multimeter, for accurate
measurement.
Battery voltage is too low.
Recharge battery.
PROBLEM: Alarm is sounding.
Low voltage shutdown or thermal
shutdown has occurred.
Shorten cables or use heavier cables.
Recharge battery. Allow unit to cool . Improve air circulation
around unit . Locate unit to a cooler environment.
Reduce load if continuous operation is Required.
PROBLEM: Battery run time is less than expected.
AC product power consumption is higher
than rated.
Use a larger battery to make up for increased power
requirement.
Battery is old or defective.
Replace battery.
Battery is not being properly charged.
Many simple chargers are unable to charge a battery fully.
Replace charger with better model such as a TRUECHARGE
smart charger.
Use shorter/heavier DC cables.
PROBLEM: AC product will not operate, red FAULT light ON.
