Flexboss - minimum battery size for parallel

[BackyardBandit]

I know that with an 18kPV or a Flexboss, the minimum recommended number of wall-mount (EG4) batteries is two.

Does that number change when doing two inverters in parallel? Would it still be two batteries (in parallel as one bank) or does that number go up?

This recommendation would be per inverter.
