 So what happens when multiple chargers are running at the same time?  Nothing dramatic, as it turns out.   So what happens when multiple chargers are running at the same time?  Nothing dramatic, as it turns out.  
  
-In general, **the charging source with the highest voltage will win**.  The only caveat is that if one of your controller uses end-amps to signal the end of Absorption, it may get confused and drop out early.((http://forum.solar-electric.com/discussion/comment/389634#Comment_389634))+In general, **the charging source with the highest voltage will win**.  The only caveat, for advanced users, is if one of your controller uses end-amps to signal the end of Absorption, it may get confused and drop out early.((http://forum.solar-electric.com/discussion/comment/389634#Comment_389634))

 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.
  
-Example.  Pretend you have a bank in a van with [[electrical:12v:alternator|alternator charging]] and a large and small [[electrical:solar:panels|solar panel]] on the roof.  Each panel has a dedicated [[electrical:solar:charge_controller|charge controller]] because the panels are of wildly different specs.  This gives us three charging sources if you are driving down the road at dawn.+Example.  Pretend you have a bank in a van with [[electrical:12v:alternator|alternator charging]] and two [[electrical:solar:panels|solar panels]] on the roof.  Each panel has a dedicated [[electrical:solar:charge_controller|charge controller]] because the panels are of wildly different specs.  This gives us three charging sources if you are driving down the road at dawn.
  
 The alternator is just a plain alternator and puts out 14.0v all the time. The alternator is just a plain alternator and puts out 14.0v all the time.
