This is freqently, dangerously, wrong- and is missing critical information.
I saw no discussion of:
* C rate
* fuse selection
* inverter precharge (capacitive loads)
* cell level monitoring
not all batteries are series compatible.
* fail modes
But, in a sentence: No more than 100Ah and 12v for your first build.
Theres a million more things- like terminal preperation, torque specs, fire precations.

- RetroTechie 2mo agoMostly 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.
