Absorb Time Limits (Advanced Menu)
The amount of time the charge controller stays in the Absorbing stage of charging can be adjusted in
the Absorb Time Limits screen. An Absorbing charge stage normally ends when the battery voltage is
maintained at the Absorbing set point for the time period set in the Absorb Time Limits screen.
 Absorb Time is adjustable from 0 to 24 hours (consult the battery manufacturer’s recommendations).
 When the Absorb Time Limit is reached, the charge controller goes into Float stage and may briefly display
Charged, then Float. When the battery voltage drops below the Float voltage set point, the charge
controller recharges to maintain this set point, employing the MPPT function in MPPT Float mode.

Absorb End Amps (Advanced Menu)
While the battery voltage is at or above the Absorbing voltage target (see page 20) and the
Absorb End Amps value is reached for a time delay of 15 seconds, the charge controller will switch to
the Float stage. This happens regardless of the charger time minutes as shown in the Misc menu
under ChgT (see page 44). The charger timer will be reset to zero.
