8. Troubleshooting

PROBLEM: AC product will not operate, no 

inverter lights are ON.

Possible cause  Remedy

PROBLEM: Inverter will run some small loads, but 

not larger ones.

Possible cause  Remedy

Voltage drop across 

DC cables.

Shorten cables or use heavier cables.

Possible cause  Remedy

Battery is defective.
Inverter has been 

connected with reverse 

DC input polarity.
Loose cable 

connection

Check battery and replace if required.
Check connection to battery. 

Probable inverter damage has occurred. 

Have unit repaired (not covered by warranty).
Check cables and connections. 

Tighten as required.
