Part of the problem is how you know when the PV is generating excess.

The other problem is finding suitable batteries. I've not seen anything that really fits the bill. It has to be safe, not take up too much space, and be easy to use/maintain (and not cost a small fortune). Most of the ones I've seen are really only a solution for people living off-grid.
