Add 2nd battery to charge EV, off grid setup

How to add LiFeP battery to my off grid house?

Have Quattro 15kV & large 48v 2000Ah FLA battery. Battery getting old. Have 41 PV, 2kW istabreeze turbine & small hydro unit. ColourCGX unit

In August EV ioniq 5 arrives, so new Victron EV charge NS looks good, can it react to SOC or just excess solar power? V2L on Car can also support house during Dec/Jan.

How to add extra quatro and new LiFeP battery, then many choices where source EV power from.

Now charging an EV car, with victron charger NS, nice ring led & digital interface. Ver1.26 seams to auto charge better with off-grid.

But same Q. how to add off-grid battery capacity?

A 60kW 48v Lithium-iron-ph would be nice, so I need another quatro - must it be same 15kV or smaller is possible?, I am sure load share is easy, separate some mppt is easy too.

Is there a priority in power consumption of 2 quatro's.

Will ccgx show two batteries?
