Multiplus: Battery charge fluctuates when feed in

My Setting: 2x Multiplus 5000, 2x MPPT RS450/100, 14.4kWh LiFePO4

With a full battery and while feeding in, the battery charge always fluctuates +/- 1000W instead of simply remaining at 0W:

Otherwise everything looks normal. At first it loads until 100% and 55,2V. After that the Apsorption stays about 54,4V.

Settings: -- DVCC without charging voltage limitation -- ESS: optimized (without BatteryLive) Any idea why the MP is doing this? Thanks!
