For grid tied system do you have your ground and neutrals bonded in the main panel or separated?
Also do you have the case of the multiplus from the back plate screw terminal connected to the same main panel bus bar / ground bar?
My distributer, who is not very familiar with grid tied systems states the ground comes from the grid and I can connect the ground and neutrals together.
I also have “ground relay” unchecked in ve configure. Enabling this would create possible ground loop? Do you have your ground relay checked or unchecked?
I have been having difficulty getting a concrete answer on this.
Thanks

This is something that is different In so many parts of the world, so it really depends on what your local code calls for.
Around here, code says neutral gets bonded at the first means of disconnect which is typically at the meter/pole for us rural guys
