Help!!! Energy taken from the grid instead of batteries

The photovoltaic system consists of:

* Inverter Victron Quattro 48/8000/110 ;

* N. 2 MPPT 250-70Tr

* 48V Victron battery bank (N.8 Victron battery LFP 200Ah 12,8V - 2 parallel of 4 in series)

* N. 16 PV panels - 390 W

* Victron Energy Cerbo GX + display GX touch 50

The problem is the following: during the battery charging phase, after reaching a SOC of at least 50%, if the energy demand of the connected loads exceeds a certain value, energy is taken from the electricity grid rather than from the batteries: why ? Which parameters need to be changed to increase the share of energy taken from the batteries instead of from the electricity grid?

I attach some photos of some parameters set by the installer and ask: should I change these values?

You have set an inverter limit of 1000W, so anything above will come from grid.

(We also have different language sections, if you'd prefer to post in your first language)

These limits were set by the installer, I have never changed anything due to lack of knowledge. What values should be set?
