Hi you could use scheduled charging in the ESS menu

Scheduled charging doenst mean it will charge at night with cheap tariffs, it can, but can also keep batteries on a minimum soc for a certain time period You can try to create different schedules that have different settings on soc and time, they run in a certain order so it could achieve what you …

Thank you. I just tried it, but got an error message when uploading the settings file to my MultiGrid II. First have to solve that issue.
