I would like to build an off grid system that I could run a couple freezers and a refrigerator off of, and use as a backup power system if the grid went down for any length. I am looking at buying from signature solar and starting with the growatt 3000 all in one

I'd also buy from signature solar this battery

I was looking at used solar panels like these.
I wouldn't use all those panels, as I have some friends who are interested in some panels as well.
One of my questions is what would be the best amount of panels to connect to this system and in what configuration? I live in Michigan, which from what I can find averages 4.1 peak hours of solar per day. I have grid power now, so I'd like to run that as a transfer source. For running my ac loads(fridge, freezer, anything else) I'd like to run the power to a subpanel. Would I need to run busbars, shunts, fuses, etc?
Thank you for any help.
