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

Only present on controllers with LOAD outputs.

• Low voltage disconnect (Vlvd) - voltage at which the controller turns off loads to prevent excessive battery discharge. Typically something like 12.1v (the voltage at 50% depth of discharge). Heavier loads that cause voltage sag may require setting a lower Vlvd so the voltage pops back up to 12.1v¹⁾ when the load is removed.
• Low voltage reconnect (Vlvr) - the setpoint at which the load is turned back on after recovering from Vlvd cutoff. Vlvr > Vlvd. If Vlvr is set too close to Vlvd the loads may continually toggle on/off.
