The current edition of UL 9540 limits the maximum energy capacity of an individual electrochemical ESS for residential use to 20 kWh (72 MJ). Currently, there is no requirement in UL 9540 for these units to be marked "Residential Use," but such a marking has been proposed for UL 9540 for the next edition. However, current UL Marks may or ...
