Also if set to either of the above what will happen to the sustain voltage?
Up to 8 attachments (including images) can be used with a maximum of 190.8 MiB each and 286.6 MiB total.
It is not advised to use 100% SOC as setpoint, but rather to use a lower value or ''keep batteries charged''.
Both WILL discharge the battery if the grid is disconnected.
The sustain voltage is a floor voltage, so regardless of either of those settings, the battery will not discharge below that sustain voltage point. In both those above cases, the battery should not be doing much discharging anyway so the sustain voltage will not come into play.
I explain this further using some helpful motion graphics in an Introduction to ESS Online Training video course that is available here with a free registration -
