The pv inverter assistant needs to be loaded into the multi however yes in period of a ramp up in PV production, sun burst etc... the Grid tie inverter wont ramp down fast enough and will trip out a inverter generator.
I found that AVR gensets handle the short overload a lot better.
Maybe you can use the energy to drive a compressor or motor to store this energy. Or pump water up... and let it go down when needed this energy again.
Just a thought.
