Multiplus II MPPT setup with PV

How to optimally configure a Multiplus II 48v-5000W with two Pylontech batteries, 2 MPPT with solar panels?

The configuration must allow to avoid the excess charge of the batteries and to direct the excess towards the network.

Can this operation be controlled by an external automation or even disconnect the batteries so that they no longer receive a charge? They will normally be little used. It is in backup mode operation.

I read that it needed 4 Pylontech US3000C batteries with a Multiplus II 48v-5000W to optimize the charge. I do not understand well because the charge is managed by the batteries (DVCC activated) whether there are 2, 4 or 6 it should not change anything.

Thanks
