Multiplus 2/5000 with 25khw of pylontech. Using ess I set min soc @ 40%. This works fine. Occasionally, I want to discharge more deeply, eg, because my wholesale tarrif is unusually high and I am prepared to risk running out in the event of an outage.
But I've found that setting min soc to 30 for example is ignored, and I am drawing from the grid, with the battery sitting at 40%.
Is there some other limit I need to check?
Thanks

Could be active SOC if you are using battery life. Confirm nothing else is showing like sustain?
Ok, sorted.
I found I had a 40% soc set in veconfig.
Must have been leftover from my previous agm battery.
I also updated the ess assistant and venus to 3.33
Now down to 30 as set. 49.1v
Thanks for the pointers.
is battery life on? this can prevent a lower SOC
Battery life not on. No other indicators, except for a low battery alarm at 48.75 (I see previous alarms at various voltages, 48.42, 48. 94 etc. But they don't seem to align with the 40% limits.)
Maybe voltage drop under load then.
With ESS what are your dynamic cut off voltages?
Is the pylon set as the system battery monitor?
If you have low bat alarms before 40% check if bats are balanced it would be logical for the system to ignore SOC if low bat alarm. VE settings? 48.75 would be around 15% SOC...
