-  * the vagaries of voltage sag across the system may result in the various charging sources seeing slightly different voltages.  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 differently.  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 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 +  * 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.   
-  * theoretical:  low-frequency PWM controllers in parallel with MPPT controllers may confuse the MPPT with a varying Vbatt reference. +  * theoretical:  low-frequency PWM controllers in parallel with MPPT controllers may confuse the MPPT with an unstable reference voltage
