Hello Bush. I don't know about legal stuff but I do know that if a new system is installed they usually want to have new panels and inverters etc.
By doing it yourself with second hand panels you would save money but you will need a licenced electrician to wire the inverter into the switchboard.
A Hybrid inverter can do what you want, they can run off batteries to run the house and also feed back into the grid.
Or you could have a manual change over switch fitted by an electrician to the switchboard and use any gear you want. It would just mean that when you wanted to run off the grid that you change the switch over manually and then nothing can go back to the grid at all. A double pole changeover switch is what is needed to do that.
I am fully off grid and have been now for over 40 years so don't bother with grid stuff.
But I do know that it is legal to have a changeover switch fitted to the switchboard to use either a generator or off grid system to power the house.
There are many hybrid inverters around that will do what you want.
From what i have seen of Victron gear is it not easy to repair if things go wrong.
Good luck
