The problem is we need to store for a lot longer than a reasonable sized battery could ever provide. That, and we still need to charge it at a time when solar and wind are low, so you need more generation to do that.
Batteries are great for daily fluctuations but once you look at covering lulls longer than a few hours they don't do that.
