Status
active

This signature is a Low State of Energy alert raised by a Megapack battery system when its stored energy has fallen to a very low level. When the alert is active, at least one battery module has already switched into its protective battery off state. The alert is also published as a DNP3 status point in the controls and communications point list, so SCADA or plant monitoring can read it remotely. The alert has priority P1 and is handled on a critical path, because leaving the system at low state of energy can permanently damage the cells. The customer's first step is to try sending a charge command to the system and, if that does not work, to contact Tesla Industrial Storage Support. The alert also raises a Tesla alarm for remote review, and a field service ticket is opened if the problem cannot be fixed remotely.
