Minimun Soc seems to be reset back to 20% every day or even more often in DESS. I cant understand why. I set it back to 0% but if I wait an hour or so it is back to 20% again… How come??
A minimum SOC of 0% is really quite low, isn’t it? I set my minimum SOC based on the season automatically: 40% in winter, 20% in summer. Perhaps you have something similar implemented? Maybe your system automatically adjusts the minimum SOC whenever the BMS issues a “low battery” warning.
No one will be able to help you if you don’t provide at least some information about your system.
Maybe implemented something in Node-RED?
Yes, I can change it back via Node Red but thats not rellly solving the problem 
0% is more like an example. Evan if i set it to 10% it will go back to 20% again…
My system is 3-phase DESS (3xMPII 3000 48V), Cerbo GX, 2 x 2P16S LiFePo4 packs with 123BMS oh each pack. Everything is on latest available non beta firmware.
Mode: Optimized without battery life
Scheduled charge levels: Inactive
What happens if you temporary disable ALL “Node Reds”, set Minimum SOC to 10% and wait….

I get your point
I’ll try that.
With Node red disabled Minimun still goes back to SoC: 20%
Cerbo GX is also updated to 3.70.
Do you have a battery with comms? Does the battery send a do not discharge to the system?
Yes, the BMS (123 Smart BMS) is connected to Cerbo GX via USB.
Finally solved. It is EVCC’s default setting to set home battery minimum SoC to 20%.
By setting it it to -1 min EVCC battery config, it does not touch the minimun Soc of Victron DESS Battery.
