Mostly missed a proper discussion of grouping batteries (parallel & series). Battery University has this page on the basics: https://www.batteryuniversity.com/article/bu-302-series-and-parallel-battery-configurations/ https://www.batteryuniversity.com/article/bu-302-series-and-... Also, physical safety could do with more discussion. How to prevent random falling objects from short-circuiting terminals (battery boxes & co!), what happens when wires are pulled on, where to locate batteries in/next to a building, etc. Also: article focusses on the energy-independence aspect. But starts with the emergency-backup aspect. These are 2 different scenarios with very different requirements! (although the described setup would surely cover their emergency case) Still: imho a decent read on considerations for a DIY solar setup.
