13. TROUBLE SHOOTING
No AC output; red LED lit, green LED not lit
Possible Cause
Suggested Solution
DC input below 10volts(battery low voltage)
Recharge or replace battery
Inverter overheat
thermal shutdown
Remove or reduce load, wait for inverter to
cool
No AC output; red & green LED not lit
Possible Cause
Suggested Solution
Inverter fuses open
Open the inverter case, change the fuse. Or
contact technical support.
Non-continuous AC output; red LED lit on & off, green LED lit
Possible Cause
Suggested Solution
Inverter output power limited by
overload/short circuit protection circuit
Reduce load or remove short circuit
The AC voltage you measured too lower
Possible Cause
Suggested Solution
The voltmeter you used not a true “ RMS”
meter
Change to use a true “RMS” voltmeter when
you measure the AC voltage output from
“modified sine wave inverter”.
No AC output (latch up); red & green LED lit
Possible Cause
Suggested Solution
Earth fault protection is activated by
excessive current leakage from the load
Unplug the faulted load
The battery backup time shorter than expect
Possible Cause
Suggested Solution
The inverter you choose too
small
Please choose more bigger power inverter
Battery poor quality or
damaged
Replace the battery
Battery empty or lower voltage Recharge for the battery, or use good quality charger to
charge the battery.
