I have an installation in my house with a Fronius Primo 8.2 and 8000W of solar panels.
I want to put a Victron Multiplus II with battery and I have doubts about how to make the connection.
This is the scheme of my electrical panel.
This is the Victron schema:
To avoid having to comply with the 1:1 rule, by which I would need two Victron to support the 8000W of the panels, I want to put a single Victron MultiPlus II 5000VA. So that if the street grid goes down, even if the panels stop producing, I still have light at home. It is something punctual that happens at most twice a year and only for a few minutes. I don't want to separate in Loads and Critical Loads, I want that all the house will be power by the Victron.
I have been told that I have to connect the Fronius to the AC-IN of the Victron and in AC-OUT connect the house, as if the whole house were critical loads.
How would the connection be made, can anyone help me?
