+> Solar and DC-DC alternator charging are going to be the best practices for maintaining charge in one's battery bank. It only requires a little math, a little discipline to stick with the math, and the right expectations about solar intake.  -- CMDR_Schrodinger((https://www.reddit.com/r/vandwellers/comments/15z8eh6/energy_management_during_trips/jxfv03f/))
 ====== Augmented solar charging ======
-Alternator + solar charging has considerable benefits over [[electrical:12v:alternator|alternator charging alone]], and over [[electrical:solar|solar alone]].  The alternator can help a small solar install punch well above its weight, [[opinion:frater_secessus:panelsizesforinsolation|acting like a much bigger install in areas of poor insolation]].((especially with PWM))  Solar can hold the bank at a higher state of charge, thereby reducing current demands on the alternator and allowing the use of smaller [[electrical:12v:b2b|DC-DC chargers]].

 Note that adding alternator charging to the mix does not necessarily require a fancy, expensive isolator;  in some ways [[electrical:12v:alternator#constant-duty_solenoid|the simple solenoid]] provides best bang-for-buck with the fewest drawbacks.((see the Gotchas section))
