lately I discovered a strange behaviour of my Multiplus. When the battery reaches the SoC limit at night, it will start to charge the batteries with around 120W from grid. It will not stop to do so even if the SoC is above the limit.
3x Multiplus II 48/3000 running Firmware 481
1x Cerbo Gx running v2.80~16-large-21
8x Pylontech US2000C
2x Fronius Galvo
How can I prevent this behaviour?
