The battery LEDs show the approximate battery state.  (See IMPORTANT note below.)  The BATTERY 
LEDs are independent of STATUS LEDs.  Any STATUS LED could accompany any BATTERY LED based 
on certain conditions.  Common combinations are noted. 

¾  A GREEN LED means the batteries have an adequate charge at that time.  It does not always mean they are 

full.  May be accompanied by a YELLOW STATUS LED when an AC source is charging. 

¾  A YELLOW LED means the batteries are somewhat discharged. 
¾  A RED LED means the batteries are greatly discharged and may require attention.  May be accompanied by a 

RED STATUS LED to indicate a Low Battery ERROR. 

GREEN 

12.5 Vdc or higher 

25.0 Vdc or higher 

50.0 Vdc or higher 

ACCEPTABLE 

YELLOW 

11.5 to 12.4 Vdc 

23.0 to 24.8 Vdc 

46.0 to 49.6 Vdc 

MARGINAL 

RED 

11.4 Vdc or lower 

22.8 Vdc or lower 

45.6 Vdc or lower 

LOW 

NOTES: 
¾  Gaps in the table (higher-voltage units) are due to the resolution of the inverter’s DC meter. 
¾  These voltage settings are not the same as the Low Battery Cut-Out (LBCO) set point.  (See pages 13 and 37.)  

The Battery LED settings cannot be changed. 

¾  Voltages higher than shown in the GREEN row usually means that the batteries are charging. 

Battery voltage does not always indicate an accurate state of charge.  It is accurate if batteries have been 
at rest for several hours at room temperature (25°C or 77°F, or as specified by the battery manufacturer).  
If they have any loads, a charging source, or are at another temperature, their voltage may not reflect 
their true state.  The OutBack FLEXnet DC is a battery monitor which can provide accurate measurements.
