 But if you want to the charge controllers (and some [[electrical:converter|converters]]) can be convinced to stay roughly in sync and keep charging together.  This is done by **configuring the Absorption and Float setpoints on the controllers to be the same**.((including Absorption termination setpoints like time or current))  There will be short periods where one controller makes a change before the other, but for most of the time both will be contributing at the same time. But if you want to the charge controllers (and some [[electrical:converter|converters]]) can be convinced to stay roughly in sync and keep charging together.  This is done by **configuring the Absorption and Float setpoints on the controllers to be the same**.((including Absorption termination setpoints like time or current))  There will be short periods where one controller makes a change before the other, but for most of the time both will be contributing at the same time.

 +===== serial charging =====
 +
 +Serial in this case means "one after another".  Sometimes the charging is done in a particular order for best results.  
 +
 +  - a high current (but fuel expensive) source handles Bulk stage that takes the battery to about 80% SoC.
 +  - a low current (but free to run) source handles the much longer Absorption and Float stages.
 +
 +In most scenarios the high current source is either [[electrical:12v:alternator|alternator charging]] or [[electrical:generator|generator]] charging.  A huge influx of power gets the battery off that deeply discharged point early in the morning.  You will know when you have finished Bulk stage when the battery starts accepting less and less current.  Since running the alternator or generator uses fuel and causes wear and tear, it's time to shut them down and use the next source. 
 +
 +The low current source is almost always solar.  Solar is free to run and is not subject to wear and tear;  it is perfect for the //hours// it will take to finish Absorption.
