Why does the Multiplus II regulate down when the carging level reaches 50%?

Hello Forum,

my setup is working well. But the inverter Multiplus II 48/5000/70/50 never reaches it charging limit of 3500W. After 50% charging level it gets down from 3000W to 2000W. What could be the reason for this behavior?.

The solar output is directed to the grid and not to the Battery.

Please advice what shoud I change in the setup?

My setup:

Battery Inverter: Victron Multiplus-II GX,
BMS: REC Q BMS 16S
Battery: 15kWH 48xCA100 Calb Cells controlled by Rec-BMS,
Solaredge Energy Meter, EM24 Emulator
Inverter: SolarEdge SE7W,
PV Modules: 18 JA Solar JAM60S10-345/MR

Are you running ESS mode or DVCC? The charge current could be limited by the bms, or by some other system setting.
