-Note:  although this page was written with alternator-augmented solar charging in mind, the general principles also apply to [[electrical:shore_power|shore power charging]] and [[electrical:generator|generator]] charging.

 Alternator + solar charging has considerable benefits over [[electrical:12v:alternator|alternator charging alone]], and over solar alone.

 The reason for this is related to how lead-acid banks charge;  they can take a ton of current in the first ~80% of charging (Bulk) then they hit a kind of wall.  At that point you could drive 100mph or hook the bank up to the Hoover Dam's electrical output and it wouldn't finish charging significantly faster.
-From ~80% to 100% (Absorption stage) charging requires little current but a long time holding at a relatively high voltage.  So in our alt+solar scenario the alternator does the heavy lifting in first bit and then a small solar install does the light (but lengthy) work at the end.
