I really appreciate your help. It made things clearer to me. At least I can say that there is no problem with the inverter. Thanks

So that means that the inverter itself is powered only by PV? Grid has no ability to power the inverter in absence of PV? I understand that the inverter will not work, i-e not supply power to the load, when there is no PV but it should at least not go into a start stop loop while the grid is present.

I think I have some deficiency in my understanding of how grid tie inverters work. When the PV goes out in the evening, grid tie inverters shutdown? I thought they will still work with the grid power and only power off during load shedding.

Link to a video I made of the inverter in that state of restart loop. https://jmp.sh/s/cP0vWD0luLdixcGlCOUL

But in absence of battery, grid power should compensate. I am sending you the latest picture of the front panel right now. It shows power being used from the grid. But after a while, it will go into that loop.

I have a three phase 12KW Inverex Nitrox(same as Deye) hybrid inverter which goes into a strange restart loop in the evening. The led lights on the inverter come on and off very few seconds. The screen does not turn on. It remains like that till the morning when sun comes out. This behaviour usually starts happening half an hour or so after PV stops producing any power. I have no batteries installed. It is currently working as a grid tie inverter. I have attached some screenshots of my settings and inverter specifications. Any clue will be really helpful. Thanks
