3.1 Stack’d Conguraon
Eachbaerystackconsistsofabaseunit,twotoeightbaerymodules,andabaery
managementmodule.Eachbaerymodulecanstore4.8KWh.Soasinglestackcanstore
from9.6KWhto38.4KWh.
AsingleHGCubeenclosurecancontainonetofourbaerystacks.Thetotalenergystored
istherefore9.6KWhto153.6KWh.Oneofthebaerystacksisconguredasstack1,the
masterstack.Theothersareconguredasslavestacks2through4.Thebaerystacksare
connectedtoeachotherusingaCANbusconnecon.Themasterstackisconnectedtothe
masterinverterusingasecondCANbus.
Thepowerconneconfromallfourbaerystacksareroutedthroughconduitunderneath
theoortobusbarsinthePowerDistribuonBox.
Thebaerystacksaredesignated1through4,whereStack#1isonthelelookingfrom
