Hello

I have a strange problem with my ESS system.
I usually let the system maintain a minimum SoC of 20%.

There are some possible grid issues in my country, and I want the minimum SoC set to 50%.

I set it to 50%, but in about 2 days it goes back to 20%

I have a 3 Multiplus II 15000VA, Cerbo, Lynx system and 8 x 16kwh batteries with JK BMS v19.
There is no Node-Red, no Dess, nothing…

I’ve found the problem on this forum.

It is the EVCC installation.
I’ve added the minsoc: -1 option to my battery section
