I'm tearing my hair out - My Multiplus is connected to an MPPS and 300ah battery stack. In the past few months the system is still taking power from mains when there is up to 100% SOC and plenty of sunlight. I do have some AC ignore rules, but these haven't changed since I first set it up. If I reset the Multi everything returns to normal - The system resumes pulling from the batteries and/or the solar. After about 12 hours it reverts to pulling, unnecessarily from mains.
