Operation
Time limit: Absorb time (m) setting. The timer counts down from the inception of Absorption
stage until it reaches zero. The time remaining can be viewed in Figure 34 .
The charger may not always run through the timer’s full duration.
The timer may expire early if the starting time was left over from a previous cycle.
The charger will leave Absorption if the charging current tapers down to the
Absorb end amps setting. This prevents holding the battery at a high voltage for
unnecessary amounts of time. The timer will retain any remaining time and use it
on the next cycle.
The Absorption timer does not reset to its maximum amount, or to zero, when AC power is
disconnected or reconnected. It only goes to zero if the timer runs out during Absorption stage
.
In other cases it retains any remaining time for use on the next cycle.
Absorb time (m) is reset to its maximum amount whenever the battery voltage decreases to the
Rebulk voltage (V) . The reset occurs immediately, regardless of the time spent below this point.
If Absorb time (m) is set to zero, the charger will immediately skip to Idle.
Idle
This is not a charging stage, but a period between stages. Following the expiration of the
Absorption timer, the unit enters (or re-enters) the Idle condition. The unit remains connected to the
utility grid, but the charger is inactive. The battery voltage will naturally decrease when not
maintained by another means such as a renewable source.

Status message: Idle
Voltage Used: Rebulk voltage (V)
setting.
Entering Bulk: Upon reaching the Rebulk voltage (V) setting.
Manual Stop
In the Action Menu , pressing Stop will end a charge cycle. The charger will return to Idle .
New Charging Cycle
If the utility grid is lost or disconnected, the unit will return to inverting mode if enabled. The battery
voltage will begin to decrease due to loads or natural loss unless charging is available from the GD
inverter. When the grid is restored, the inverter will return to the charging cycle.
Rebulk
If the battery voltage decreases due to discharge, the charger will restart the cycle as soon as the
grid is available, beginning at Bulk stage. See page 66.
If the batteries do not decrease to the Rebulk point, the charger will not enter the Bulk stage when
the grid is reconnected. It will return to its previous stage.
