LUNA2000 goes in suspend modus and don't wake up in the morgning

The battery is switching off every morning unless it isn't empty. Increasing the "End-of-discharge SOC（%）:" doesn't help. I have to manually switch on the battery every morning with the switch on the backside of the battery. The battery is only. approx.. 3 month old. The battery firmware is V100R002C00SPC106. The inverter firmware is V100R001C00SPC136I don't know, if the problem already was there in the beginning, because we had more sunshine then, so that the battery hardly ever fully discharged. Is there anything I go do?
