I'm struggling with system always resetting to 100% SOC when the solar charger kicks in. I've tried to increase the absorbtion voltage slightly (0,25V above the same in MultiPlus), but it still resets. Today it was showing 82% and as soon as the solar charger kicked in it reset to 100% again.
I have the following setup:
1x 300Ah lithium battery + 105Ah AGM starter battery
2x 160W solar panels
MultiPlus C 12|1600|70
Cerbo GX + Touch 50
