-Combining the [[electrical:solar:charge_controller|solar charge controller]] and DC-DC charger in one unit can have benefits in cleaner/simpler installation and perhaps cost over separate components.   The downsides are less configurabilty((you aren't choosing your own highly-configurable components)), single points of failure, and limited options on solar input.  +Combining the [[electrical:solar:charge_controller|solar charge controller]] and DC-DC charger in one unit can have benefits in cleaner/simpler installation, starter battery maintenance from solar, and perhaps cost over separate components.   The downsides are less configurabilty((you aren't choosing your own highly-configurable components)), single points of failure, and limited options on solar input.  
  
 Combo units typically have much **lower maximum panel input voltages** (as low as 23v) than a standalone charge controller would (60v - 150v).  This limits the solar configuration in a few ways: Combo units typically have much **lower maximum panel input voltages** (as low as 23v) than a standalone charge controller would (60v - 150v).  This limits the solar configuration in a few ways:
