So, during night, I have to set the register 47511 to 1 and at 6 o'clock (when the electricity prices are higher) I have to write 0 to register 47511. Will the battery automatically stop when it reaches 100% or, do I have to time it?

It's basically in charging mode and if battery is full, system gonna hold battery on 100%. If no sun then only house usage is imported from grid.
Short answer you don't need to time it.

But double check values. These are on hex. If you try to write 0 in that register you probably get error...
If electricity is cheap - write 2 - you gonna buy
If price is high and you want to sell back to grid (in summer time) before sun - write 3
If you want to use electricity from battery to supply home usage - write 1
If you want to hold battery state then you can write 8 - so battery gonna be on standby

Thank you for your help. I appreciate it very much!

But, I still have some question:

• The register 35137 seems to be the sum of the solar panels and the power to the battery. I suppose the register 35171 is the one the battery. But which register does I have to call to have only the power of the solar panels?
  
• Now, when the battery is discharging, is goes to an SOC of 5%. I want to avoid it, because on a raining day, instantaneous total power to the grid is high (together with the consumption of the house at that moment) and in Belgium some cost are bases on the peak values. So, I want to stop the discharging at 10%. I was trying to change the register 47351, but nothing happens. I was looking for the comparable BMS register, but I didn't find it. To which register, I have to write to top discharging at 10%?
  (since in the manual there is written: set the SOC level to start/stop battery force charge. (this is not the command from BMS, but the protection on inverter side. Eg. StartchgSOC (47531) is set as 5%, but the battery BMS gives a force charge signal at SOC 6%, then battery will start force charge at 6% SOC; if BMS does not send force charge command at 5% SOC, then battery will still start force charge at 5% SOC. )
