Solar inverter on generator or on battery inverter?

Recently, during an electrical project in my street, there was an SDMO 400 kVA emergency generator set...it did not supply my address but I still asked myself the question with regard to photovoltaics...
It is specified on the operator's site that a solar inverter automatically goes into safety when it is powered by a generator...how can the solar inverter know that it is generator current?
For a group connected directly, it's actually easy: injection is impossible...but for a group that goes through the network with other consumers, I don't quite understand...
Another question: can we simulate the network with a pure sinus inverter connected to a battery?
Given the risks of blackout to come for this winter, I would like to take a few precautions to at least be able to take advantage of my photovoltaic production in the event of a power cut!
