 +===== higher bank voltages =====
 + 
 +Although 12v house banks are most common there are use cases where higher bank voltages (24v, 48v, etc) may be desirable:
 +
 +
 +  * when some big DC load demands it (DC minisplit aircon?)
 +  * when 12v inverter size approaches 3000w((sometimes seen on propaneless "all electric" setups))
 +  * when someone stumbles into a great deal on a higher-voltage pack (Leaf battery fell off a truck)
 +  * when the vehicle has a 24v alternator, as found in some commercial vehicles like buses or box trucks
 +
 +
 +Challenges:
 +
 +  * limited options charging from normal 12v alternators <-- even more niche than the inverter market
 +  * requirement to buck back down for "normal" 12v house loads
 +  * requirement for higher solar array voltages.
