This article defines the scope, boundaries, and requirements for solar array circuitry, inverter equipment, and control devices in residential and commercial installations.
Interconnection Methods | AE 868: Commercial Solar Electric Systems
In case multiple power sources are to be interconnected, each added power source (inverter in PV case) must have a dedicated circuit breaker or fused disconnect unless their outputs are first combined at a
Requirement for breaker feeding inverter | Information by Electrical
It depends on if that subpanel has a mix of sources and loads, or if that subpanel is dedicated to combining the outputs of the inverters. If it is a mix of sources and loads, then yes, you
