Out of curiosity, what are you using all of that power for? That sounds like a huge system.

    The battery is huge, the panels are small.

    Even 12 hours of constant sun, can't charge 32 kWh battery with just 2,4 kWh panels, and only barely with 3.5 kWh panels, when consumption is considered too.

    We have 11 kWh panels and 7,5 kWh battery. The reason the battery isn't twice that size is that battery was expensive when we had our system installed. But we would not be able to utilize more than 15 kWh battery for our household.

    Realising it was 2.4 to 3.5 on the roof, not as well. Plus the 3 on the ground. Still a fair size though.

    With 3.5 on the roof, and 3 on the ground it is enough for an average household if there is a lot of sun. And most places it should be enough at least during the summer.

    That much would pretty much cover my usage in winter, summer I would be exporting the vast majority of it.

    Which I probably should do, my provider gives not awful export rates. So might be worth just going pure solar for now and look at batteries later if export rates fall. IIRC it is like 60% or so what you would pay to buy energy you get for selling it. So if my panels make more than I use and I can shift a good amount of usage to daytime, free energy for a few decades after it's paid for the install.
