 OEM converters are notoriously cheap and dumb (lacking [[electrical:12v:charging|smart charging]] functions).  Since they are stuck at one voltage the manufacturer picks a compromise setpoint.  If this is set too high or too low //for your usage patterns// it can damage lead-acid batteries ([[electrical:batterycide|batterycide]]). OEM converters are notoriously cheap and dumb (lacking [[electrical:12v:charging|smart charging]] functions).  Since they are stuck at one voltage the manufacturer picks a compromise setpoint.  If this is set too high or too low //for your usage patterns// it can damage lead-acid batteries ([[electrical:batterycide|batterycide]]).
  
-This compromise setpoint should coincide with standard float voltages for your battery bank.  Typically this would be 13.2v - 13.4v for converters that are always on the grid, and 13.8v for batteries that are cycled but get put back on grid charging regularly.+This compromise setpoint should coincide with standard float voltage (Vfloat) for your battery bank.  Typically this would be 13.2v - 13.4v for converters that are always on the grid, and 13.8v for batteries that are cycled but get put back on grid charging regularly.((Solar charging at a single setpoint, as with a [[electrical:solar:charge_controller&#shunt|shunt controller]], is done at [[electrical:solar:shunt_tweaking|Vabs rather than Vfloat]].))
