Generators compatible with Fronius grid tied inverters.

We have a Fronius grid tied inverter connected to the output of a Quattro. Fronius grid tied inverters have a shutdown facility which utilises frequency shifting the ac by 1 Hz.


Suppose we have an ESS with a Fronius, Quattro and a generator. If the generator kicks in and the frequency is not exactly 50 Hz, the Quattro will frequency-track it and in doing so inadvertently shut off the Fronius grid-tied inverter.

Do we have to purchase a super-stable generator with exact 50 Hz frequency in order to prevent conflicts between the frequency of the generator and the grid-tied inverter?
