What is the use of notch filter in Fig3 of the user's guide TIDU405.
In Fig. 10 of the user guide TIDU405, PLL functioning has been explained and told that PLL is used to synchronise the inverter output current to grid voltage so my question is:
If the grid voltage gets distorted, will the inverter current will also be distorted.

Sanjay,
Gautam answered the notch filter questions, for the PLL question we have application report that compares performance of the PLL under different distortions
Yes there will be distortion, but if you use SOGI PLL it is a selective filter for the grid frequency and hence the distortions will be less, i highly recommend using SOGI PLL it's available in solar library
Good luck with your project,
regards
Manish
