If the inverters are in parallel, the batteries must all be in parallel. Create a common bus and connect the 2 inverters to the bus.
The batteries will have one master and 3 slaves.
The inverter will have a Master and Slave.
The master battery comms connects to the master inverter using CAN bus.
You say yo have 9kW of PV, but not what size panels. Lets assume you have 20*450W panels. To ensure that you maintain a good Voc I would suggest you split this in to 2*10 panels strings and use the master inverter, however for redundancy you could put one 10 panel string on each inverter.
