In general, **the charging source with the highest voltage will "win"**. | In general, **the charging source with the highest voltage will "win"**. |

Some commercial products integrate charging from multiple sources into a single unit. [[https://www.renogy.com/dcc50s-12v-50a-dc-dc-on-board-battery-charger-with-mppt/|Renogy's DCC50s]] (or smaller DCC30s) are popular because they combine an MPPT solar charge controller with an Alternator charge controller into a single easy package. | Exeption: some commercial products integrate charging from multiple sources (like [[electrical:12v:b2b#examples_-_combo_with_solar_charge_controller|combination DC-C chargers]])into a single unit so there is no "competition". |

Most charging involves holding((or trying to reach)) a particular voltage [[electrical:12v:electrical_notation|setpoint]].((current-terminated Absorption excepted for purposes of this discussion)) If a charging source sees the bank voltage is above its own setpoint it thinks the job is done; it sits quietly. | Most charging involves holding((or trying to reach)) a particular voltage [[electrical:12v:electrical_notation|setpoint]].((current-terminated Absorption excepted for purposes of this discussion)) If a charging source sees the bank voltage is above its own setpoint it thinks the job is done; it sits quietly. |
