4. Troubleshooting Guide
WARNING!
Do not open or disassemble the unit. Attempting to service the
unit yourself may result in a risk of electrical shock or fire.
Problem and Symptom
Possible Cause
Solution
Low output voltage
(110V: 95-105VAC
220V: 190-210VAC)
Using average reading
voltmeter
Use true RMS reading meter
and cable. (Ref. point 2-4-7)
Load display OLP flash
Over load
Reduce load
No output voltage
Fault input voltage
Low/High input voltage
Recharge battery,
check connections and cable.
(Ref. point 2-5 & point 2-6)
No output voltage
Over temp indicator
Load less than 1700W
Thermal shutdown
Improve ventilation.
Make sure ventilation openings
in inverter are not obstructed.
Reduce ambient temperature.
No output voltage
Over load indicator
Short circuit or wiring error
Very high power load
Check AC wiring for short
circuit or improper polarity. (hot
and neutral reversed)
Remove load.
