What I need to know, and I am sure there are many people asking the same question?

What document will an electrician be required to provide for a property which includes a solar installation?

I dont want to know what would be nice to add or supplementary pages you feel like adding, I want to know what is the requirement by law?

Lets say the house has a meter feeding a main DB and the DB is split, into essential and non essential ( which makes it one DB), A couple panels on the roof a single inverter and a battery.

A 1 page COC with a test report on the back.

I am going to say it again, what documents would be required by law.
