PV individual installation scalable? (network backup)

[patkersule]

Hello,

I am new to PV, but I would like to equip myself
quite simply and in an evolutionary way (it will be necessary to pass there !!!)

I surfed here and there ...

I end up with a fairly simple typical installation ...

Solar panel, charge regulator, battery -> use in 12V

+ converter if use in 220V ...

I do not wish to inject the energy produced in the national grid,
for reasons of personal convictions ...

I do not think to equip myself in heavy version for the moment,
budget problem, let's start with lighting and appliances
low power consumption.

then a question arises, when my battery (ies) are empty,
I will of course need to use the network as a backup .. !!!

(silly question mode)
what is the diagram (simple !! lol) of this system, what material
in what place, for what reason (s) ... ??

I saw systems, production - consumption - network backup, with PV priority, but I did not see any hardware details.

by equipping myself thus I wish to make evolve my installation,
addition of batteries, panels according to the means and a possible modification of needs, more or less obviously ...


thank you for your help and your experiences ...

Pat
