BATTERY LEDS

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.

¾A 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.

¾A YELLOW LED means the batteries are somewhat discharged.

¾A 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.

NOTES:

¾Gaps in the table (higher-voltage units) are due to the resolution of the inverter’s DC meter.

¾These 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.

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

IMPORTANT:

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.
