 Barring heroic measures((exotic alternators/regulators, [[electrical:12v:b2b|DC-DC chargers]])) the alternator is going to stop contributing at some point during Bulk charging.  That is ok, the alternator provided a ton of current while it was charging.
-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.

 Note:  there are high-end controllers/chargers which communicate with each other to coordinate charging.  That feature is beyond the scope of this article.
