Troubleshooting
PROBLEM: Output voltage below 100V AC
Reason
Solution
A “True RMS” voltage meter is
required to properly measure
output voltage of a modified wave
inverter.
Test output voltage with a “True RMS”
and the correct voltage will be displayed.
PROBLEM: No Input Voltage
Reason
Solution
Poor contact with battery
terminals.
Shut down inverter and disconnect.
Clean terminals thoroughly and
reconnect.
Blown DC battery fuse(s).
Turn off inverter. Fix problem. Replace
fuse(s) with same type and rating.
PROBLEM: Inverter is Shut Down
Reason
Solution
Battery voltage below 10 Volts.
Charge or replace battery.
Inverter is too hot (thermal shut
down mode). Will be indicated on
LCD panel.
Allow inverter to cool. Check for
adequate ventilation. Re-duce the load
on the inverter to rated continuous
power.
Unit may be defective.
See warranty and call customer service.
PROBLEM: Low Battery Alarm on all the Time
Reason
Solution
Input voltage below 10.5 Volts. Will
be indicated on LCD panel.
Keep input voltage above 10.5 Volts to
maintain regulation.
Poor or weak battery condition.
Recharge or replace battery.
Inadequate power being delivered to
the inverter or excessive voltage
drop.
Use lower gauge (heavier) cable. Keep
cable length as short as possible.
PROBLEM: TV does not Work
Reason
Solution
TV does not turn on.
Contact TV manufacturer to find out if the
TV is compatible with a modified sine
wave.
