A battery can store power generated on your own roof, but some systems can also charge from the grid. The economics depend on tariff, charging schedule and how much stored energy you actually use.
What you gain
Storage may shift some electricity consumption from one time of day to another. That can help a home use more solar production or a suitable off-peak tariff.
What it cannot do
A battery does not automatically cut costs. It has an upfront price, finite capacity and energy losses, and the best charging routine may change with tariffs.
Size matters
A household with high winter heating electricity demand may need a very different setup from a small home that mainly uses power in the evening.

A transparent quotation should compare equipment cost, expected cycles, tariff assumptions, warranties and realistic yearly savings.
