Bluesolar charger for Multiplus inverter

A friend got this system installed: three Multiplus 48/3000 inverters configured for 3-phase operation, operating with 4 pcs Monbat ML220C batteries. The batteries are charged with 3 Bluesolar MPPT 150/70 chargers.

My question is: are the Bluesolar chargers necessary? Couldn't the Multiplus inverters do the charging directly, without using the separate MPPT chargers? Or is it any advantage on doing this?

@Fritz The main advantage is the bulk of the charging can be done from Solar panels not from grid or generator power. The second advantage is, if the programming is done well and the PV system well set up, the loads in the system can be powered from the solar panels as well.


Addition mod edit: The MPPTs are required to connect and regulate DC solar panels. The Multi's are only able to charge and regulate from AC supplies like generators and the grid.
