 Boosting solar charging with alternator, genny, etc, works best during bulk stage.  This is true for alternators because their terminal voltage is rather low, and for both generators and alternators because Absorption stage takes little current and a great deal of time.
-In practice, it is generally ideal to start the charging from 50% [[electrical:depth_of_discharge|depth of discharge]] for best fuel efficiency.  The generator would be shut down when Absorption voltage is attained and current has fallen off to a point solar can handled it.  Alternator charging would be shut down when house battery voltage stabilizes at alternator voltage.
