or eliminate the problem:
Use an extension cord to increase the distance between the inverter and the TV, antenna and
cables.
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 inverter.
5. Troubleshooting
PROBLEM: AC product will not operate
Possible Cause
Suggested solution
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. Tightens required
PROBLEM: Inverter will run some small loads, but not large ones.
Possible Cause
Suggested solution
Voltage drop across DC cables. Shorten cables or use heavier cables.
PROBLEM: Measured inverter output is too low.
Possible Cause
Suggested solution
Standard ”average-reading” AC
voltmeter used to measure
output voltage, resulting in an
apparent reading 5 to 15 volts
too low.
Inverter’s “modified sine wave” output requires “true RM”
voltmeter, such as Fluke 87 series millimeters for accurate
measurement.
Battery voltage is too low.
Recharge battery.
PROBLEM: Alarm is sounding.
Possible Cause
Suggested solution
Low voltage shut down or
thermal
shutdown
has
occurred.
Shorten cables or use heavier cables. Recharge battery.
Allow unit to cool. Improve air circulation around unit.
Reduce load if continuous operation is required.
PROBLEM: Battery run time is less than expected.
Possible Cause
Suggested solution
AC product power consumption
is higher than rate.
Use a larger battery to make up for increased power
requirement
Battery is old or defective
Replace battery
