Solar charge controller setpoints
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
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.
