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. | 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.

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. Even if they contribute unequally it is a non-issue because the voltage setpoint is being held. | 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.

Even if they contribute unequally it is a non-issue because the voltage setpoint is being held. If a big load is added or conditions deteriorate it will be "all hands on deck" as in the Bulk stage scenario above. |

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