Troubleshooting guide
Problem Possible
cause
Solution
Low output voltage (96 to 105 volts)
Using a voltmeter which cannot
properly read the RMS voltage of
a modified sine wave
Use a TRUE RMS reading voltmeter
Fault indicator ON
Low input voltage
High input voltage
Short circuit or AC wiring error
Inverter overload
Not enough battery capacity
Recharge batteries
Improper installation. Check each
inverter’s installation steps
Check vehicle alternator conditon
Check the AC wiring (120 volts) and
test your appliances on an other power
supply to validate their fonctionality
Remove or reduce load, switch the
inverter OFF at least 5 second and
restart the inverter
No output voltage
Inverter off
No DC power to the inverter
Reverse DC polarity
Turn the inverter on
Check the wiring
Check battery fuse et check the
installation before changing it
Replace internal fuses of the inverter.
Damage caused by reversed polarity is
not covered by the warranty.
Alarm on all the time
“LVP” code on remote display
Poor battery condition
Poor DC wiring
Poor DC terminal lugs connections
Charge or change battery
Use proper cables and make solid
connections
Use proper crimping tool
Overheat indicator on
Thermal shutdown
Improper installation
Reduce load
Allow inverter to cool off
Improve ventilation
Install properly
