AC-coupling and the Factor 1.0 rule
Most brands of PV inverters can be used for these systems, they need to be setup to support frequency shifting, often called the island-mode or micro-grid mode.

Several Sunny Island inverters can be operated in an off-grid system. Three Sunny Island inverters are connected in parallel on the DC side and form a cluster.

These systems operate as either grid-following or grid-forming inverters, each playing a distinct role in power system stability and control.

Voltage-source (e.g. grid forming) inverters do have the ability to support islanded operation. Inverters are found in PV systems, wind turbines, microturbines, fuel cells, and battery energy storage.

It used to be such that mixing IQ7 and IQ8''s was not recommended, but since version 8 of the Gateway firmware, yes, it is possible. Of course, you will not mix IQ8''s and IQ7''s on the same branch circuit.
