In the near future I will research this more but a general way of thinking is this: monitoring of batteries is indeed a must! This i will approach with arduino/raspberry eleftronics. An arduino can monitor one or more batteries (don't know now) and a raspberry monitoring the data of the arduinos and decide which batteries needs charging. During charging that battery will be disconnected from the batt-bank, so the high charging voltage will be not exposed to connected electronics. So every battery will get it's own "address". Its probably already somewhere on the internet.
Further research will go into supercapacitors connecting to solarpanels as they should be very helpful in starting electromotors, which often require almost double the power during startup (need less panels and better for connected batteries).
Also, a 3rd aspect will be small setups. Panels near point-of-use. Cuts costs on cable.
Anyway, i'm in the process of building my home now. Probably move there in september, so then the thinkering starts....
