Controller behavior is guided by setpoints, or values stored internally. On simpler controllers the setpoints may not be adjustable. On others there is a range of values that can be stored.

• Float voltage (Vfloat) - the voltage the battery bank is held at during Float. Common setpoint in most configurable controllers.
• Absorption voltage (Vabs) - the voltage the battery bank is held at during Absorption. Common.
• Absorption duration - the amount of time Vabs will be held until dropping to Vfloat. Somewhat common.
• Absorption termination - the amount of current (or percentage of capacity) Absorption must fall to before dropping to Vfloat. Not common.
• Absorption restart - voltage (or duration) at which Absorption stage after failing to maintain Vfloat
