-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]].))+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]].))

 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 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.+Example.  Pretend you have a bank in a van with [[electrical:12v:alternator|alternator charging]] and 400w of [[electrical:solar:panels|solar panel]] (2x200w) 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.
