For a single home? No, it's not that complex, but can be expensive depending on total needs. Average cost is $15-16,000 USD to start and goes up for more capacity.
Grid level storage? Much more complex.
The goal isn't to have 99.99999999% grid uptime. It would be supporting known common events. It's night? You don't have solar? Strong storm? Wind is parked. A foot of snow, and then overcast for the next week with the 8.5 hours of sunlight per day? Much more difficult.
