I ran fine with 2kWh storage and 1.6kWp, so yeah anything bigger than that might idle and therefore just delay breaking even.

not using the full 800W at noon on workdays

That's why I would still recommend any battery. Not just to save some energy into the evening where electricity prices regularly spike in germany, but also to store in short-term when running a laundry machine on a so-so day.

Nonetheless, those small solar plants are likely always viable and I do regularly recommend them even if not asked :)
