3. Maintenance:
Very little maintenance is required to keep your inverter operating properly.
You should clean the exterior of the unit periodically with a dry cloth to prevent
accumulation of dust and dirt. At the same time, tighten the Screws on the DC input
terminals.
4. Troubleshooting guide:
Problem and Symptom
Low output voltage
(110V: 95-105VAC
220V: 190-210VAC)
Load display OLP flash
No output voltage
Fault input voltage
No output voltage
Over temp indicator
Load less than 1500W
No output voltage
Over load indicator
WARNING!
Do not open or disassemble the inverter. Attempting to service
the unit yourself may result in a risk of electrical shock or fire.
Possible Cause
Using average reading
voltmeter
Over load
Input Undervoltage
Input Overvoltage
Thermal shutdown
Short circuit or wiring error
Very high power load
Use true RMS reading meter
and cable. (Ref. point 2-4-7).
Reduce load
Recharge battery,
check connections and cable.
( Ref. point 2-5 & point 2-6)
Improve ventilation.
Make sure ventilation openings
in inverter are not obstructed.
Reduce ambient temperature.
Check AC wiring for short
circuit or improper polarity. (hot
and neutral reversed)
Remove load.
