LFP much less likely to run into thermal runaway, during a house fire LFP would still ignite and burn hot until all the ‘fuel’ is gone. The considerations here seem to point out making sealed modules would abrogate this consideration and some ‘best practices’ seem to point out stacked BESS units should be at least 3 feet separated and battery stacks kept less than 20kWh. What would solid-state battery cell designs mean to 9450(A) and NFPA 855? Right now the only actual consumer product that’s been advertised is the Yoshino BESS from $330 for 300 watt to $3,300 for 4000 watt systems, for the battery/inverter module, solar PV panels extra cost adders.

(IF) one can get these solid-state batteries into BESS units and use the stacked format it might allow stacking more modules vertically to say 30 to 40kWh modules that meet NFPA 855 and pass 9540(A) certification.
