Note: LiFePO4 is preferred for stationary storage due to safety and cycle life (3000-6000 cycles). NMC has higher energy density but shorter cycle life.
Reference
Series Cells = ceil(System Voltage / Cell Voltage)
String kWh = Series x Cell V x Cell Ah / 1000
Parallel Strings = ceil(Target kWh / String kWh)
Max Power = Actual kWh x C-Rate
