So what happens when multiple chargers are running at the same time? Nothing dramatic, as it turns out.((The only caveat, for advanced users, is if one of your controller uses end-amps to signal the end of Absorption, it may [[http://forum.solar-electric.com/discussion/comment/389634#Comment_389634|get confused and drop out early]]. Also see these potential [[electrical:12v:alternator#gotchas|isolator gotchas]].)) | So what happens when multiple chargers are running at the same time?

In general, **the charging source with the highest voltage will "win"**. | In general, **the charging source with the highest voltage [[electrical:solar:charge_controller_setpoints|setpoint]] will "win"**. |

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". | Exeption: some commercial products integrate charging from multiple sources 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. |
