>>Why should a house-installed solar installation use batteries at all? Â Batteries are big, heavy, inefficient, have a limited lifetime, and are made of expensive and potentially toxic materials, which can sometimes explode with little or no warning.

Apparently you completely misunderstood what I said.

But a given house can treat the AC grid as if it's a "battery". Â If the solar panels generate more electricity than the house happens to be using, they will throw the power into the AC grid, and in effect run the meter backward. Â The power-generation systems don't have to work as hard, when they are partly supplied by excess residential electricity.
