 Some of these are observed, and some are theoretical. Some of these are observed, and some are theoretical.
  
-  * the vagaries of voltage sag across the system may result in the various charging sources seeing slightly different voltages and therefore contributing differently.  Voltage Sense wires can help with this issue.   +  * the vagaries of voltage sag across the system may result in the various charging sources seeing slightly different voltages and therefore contributing in unpredictable ways.((probably a non-issue as long as the bank is getting properly charged))  Voltage Sense wires can help with this issue.   
-  * Multiple controllers set up to trigger Float from endAmps((trailing amps)) may enter float early since they are providing only some of the charging current. +  * Multiple non-communicating controllers set up to trigger Float from endAmps((trailing amps)) may enter float early since they are providing only some of the charging current. 
-  * Multiple sources may inadvertently exceed the bank's recommended charging current.  Example:  a lithium battery wants 50A max but each charging source can make 30A.  This might result in overcurrent (60A) during Bulk.   +  * Multiple sources may inadvertently exceed the bank's recommended charging current, or your preferred current.  Example:  a lithium battery wants 50A max but each charging source can make 30A.  This might result in overcurrent (60A) during Bulk.
