(1) There is no limitation to installing a HELIOS ESS battery above or below other HELIOS ESS.
(2) The room volume protects against explosion in the unlikely event of a battery releasing explosive gases and entering thermal runaway. In normal operation, LiFePO4 batteries do not release any hazardous gas. If the room has a 9 ft ceiling, 1,148 ft3 equates to a minimum room size of 10 x 13 ft. Room sizing does not increase if installing more than one battery.
(3) If the room is smaller than prescribed, adding vents, deflagration vents, or a constantly running air circulation system could reduce the required room size. A certified safety engineer should determine the venting and volume of air circulation required.
(4) UL9540A definitions for residential and non-residential use.
