MPPT RS & Pylontech Float voltage

I have an off-grid system with 2 x US5000 battery bank.

As I want to add a heatting/cooling pump to mu mountain house, I will need to increase a lot my PV production. Of course my battery capacity and inverter power too.

I am thinking to use a MPPT RS 200A and the mppt sizing calculator requieres the float voltage of the battery.

The pylontech US5000 datasheet (see file attached) does not provide the float voltage but only the charge voltage: 52,5 - 53,5..

Reviewing the VRM charge history, I see that the battery is charged at 52,3V by the actual smartsolar

Is the 52,3V the float foltage or I have to use the any value between the charge voltage range mentiined in the datasheet?
