What is an activation event and how do activation credits work?
A peak demand period would likely trigger a Battery Rewards activation event. No action is required from you as it is managed through the cloud communications software within your battery inverter. Your unused stored energy from your battery would then be sent to the energy system to help balance demand, and you would receive activation credits (70 cents per unit) exported to the energy system during the activation event.

Depth of Discharge
This is the level the battery is set to discharge to and is crucial to ensure the longevity of certain battery chemistries. Lithium ion batteries (and some other types) are never fully discharged, because that would have a detrimental effect on the life of the battery. For example, if the depth of discharge was 80%, the battery would shut off and not provide any further power once it reached 20% of its capacity. Older lead acid batteries typically are set to discharge to about 50% and more modern Lithium Ion batteries are able to have much higher depths of discharge up to about 90%. If manufacturers advertise 100% depth of discharge, they usually have a buffer of battery capacity that they do quote on their data sheet.
