Symptom 

Possible Cause 

Recommended Solution 

Inverter will not turn on during 
initial power up. 

Batteries are not connected, loose 
battery-side connections. 
 
Low battery voltage. 

Check the batteries and cable 
connections. Check DC fuse and 
breaker. 
 
Charge the battery. 

No AC output voltage and no 
indicator lights ON. 

Inverter has been manually 
transitioned to OFF mode. 

Press the switch to Power saver on 
or Power saver off position. 

AC output voltage is low and the 
inverter turns loads OFF in a short 
time. 

Low battery. 

Check the condition of the 
batteries and recharge if possible. 

Charger is inoperative and unit 
will not accept AC. 

AC voltage has dropped 
out-of-tolerance 

Check the AC voltage for proper 
voltage and frequency. 

Charger is supplying a lower 
charge rate. 

Charger controls are improperly 
set. 
 
Low AC input voltage. 
 
Loose battery or AC input 
connections. 

Refer to the section on adjusting 
the “Charger Rate”. 
 
Source qualified AC power.. 
 
Check all DC /AC connections. 
 

Charger turns OFF while charging 
from a generator. 

High AC input voltages from the 
generator. 

Load the generator down with a 
heavy load. 
Turn the generator output voltage 
down. 

Sensitive loads turn off 

Inverter's Low voltage trip voltage  Choose narrow AC voltage in the
