Lots of flickers on load side during daytime with Fronius setup

I am getting a lot of flickers during the day from my Victron system that has a Fronius inverter AC coupled to it. Currently, a PV support assistant is used to regulate the output of the grid-tied inverter by using frequency control. Can this have an effect on the loads, especially ones connected to UPSs

@Philip Kamau

Common with Fronius PV inverters especially with low light and low load conditions.

With UPS's since they are designed to be fussy about power, the frequency will be messing with their sensitivities.

If you contact them (Fronius) directly they can help with a few deeper settings to smooth it over a bit.

Please Install the firmware version 31330

After installing you need to choose the mg50 if you grid is 50hz or 60hz instead.
