+A [[http://amzn.to/2pN3O9o|12v timer]] could give the system a chance to make some progress in Absorption before starting up opportunity loads.  If mistimed or overly heavy loads applied, Absorption duration could be affected.

 This setup looks like:  [LVD or controller LOAD output] --> timer --> relay --> load
+==== LVD + timer - eternal Absorption ====
+This setup avoids timer juggling/estimation and does not affect Absorption charging.
+  - set Vfloat to Vabs
+  - observe measure how long Absorption actually takes to drop to [[electrical:solar:charge_controller_setpoints|endAmps]] on your system
+  - set the LVD to just under Vabs, set the timer to the Absorption duration
