ESS - peak shaving depletes Battery below minSoC even with no AC current limit set

Hi All

subject says it all…
Tonight, battery reached minSoC for the first time after ESS peak shaving had been introduced (v3.30).
I never cared about the setting, having a 3ph 63A grid connection, so no limits were actively set in the GX.
Tonight, when minSoc had been reached, the battery continued to discharge with a very low wattage (around 27-45W), but still not zero/going to idle.
This morning, the battery Soc had reached 7% :frowning:
Why didn’t ESS stop discharging the battery at minSOC?
Even when I now set AC current limits (to 62A) the system still depletes the battery while AC currents are not anywhere near that limit.
Only when I set the mode to “above minSoC only”, the battery goes to idle.

…I feel pain between my ears…eager to understand that behaviour.
