Section 8: Troubleshooting the 20-1050CUL-DC 

 
The  following  are  the  most  common questions heard  by  Vanner  service  professionals.  If  your  situation 
does not apply to the following categories, please contact your local Vanner Inc Distributor. 
 

Vanner Inc Customer Service: 1-800-AC-POWER 

 

SYMPTOM

 

All of the LED’s on the front panel blink one at a time, in sequence. 

 

SOLUTION

 

It is normal for this to occur if the inverter switch is On when the DC input is connected to 
the  unit.  If  the  DC  is  already  connected  and  the  LED’s  blink  in  sequence  then  the  DC 
input is dipping in voltage. 

 

Check for poor connections in the DC wiring, bad battery, or a heavy DC load. 

 

SYMPTOM

 

ON lamp flashes or does not light steadily after pushing in the ON-OFF/RESET Inverter 
Switch. 

 

SOLUTION

 

Lamp flashes when utility power is present. Lamp flashes in Load Demand Waiting mode. 
Check/Reset GFCI on the receptacle. See * Note on page 6.  
Check battery connections if utility power is OFF 
Check DC fuses if utility power is OFF 

 

SYMPTOM

 

ON lamp fully illuminates. AC load does not run. 

 

SOLUTION

 

Check and reset circuit breaker. 

 

 

Check and reset GFCI. See * Note on page 6. 
Verify AC load and cord is in proper condition. 

 

SYMPTOM

 

BATTERY LOW lamp illuminates when AC load is applied. 

 

SOLUTION

 

Check battery connections. 
Check battery condition. 
Recharge battery if voltage is less than 10.5 VDC.  
Check the vehicle's alternator charging system for proper operation. 

 

SYMPTOM

 

OVERTEMP lamp illuminates. 

 

SOLUTION

 

Something  has  caused  the  unit  to  overheat.  Check  for  obstruction  of  air  flow  to  the 
cooling fan or from ventilation holes. Verify AC load is within unit's rated capacity. 

 

SYMPTOM

 

OVERLOAD lamp illuminates with AC load applied. 

 

SOLUTION

 

Verify AC load is within unit's rated surge and continuous capacity. 

 
 

SYMPTOM

 

DC fuse blows when connecting DC input cables. 

 

SOLUTION

 

Check  for  reverse  polarity:  red  cable  to  battery  positive  (+),  black  cable  to  battery 
negative (-). The unit may be damaged and require repair service. 

 

SYMPTOM

 

Low battery lamp glows dimly when inverter is off. 

 

SOLUTION

 

This is normal.
