A battery storage system stores excess electricity (usually from solar panels) so you can use it later instead of drawing power from the grid.

No. Batteries can charge from the grid, but they’re most effective when paired with solar to store your own generated energy.

Savings depend on your usage and tariffs, but you can reduce bills by using stored energy during peak (expensive) times instead of buying from the grid.

Most modern systems last 10–15 years and come with warranties based on cycles or time.

Some systems can, but you’ll need backup functionality (like EPS or full backup) installed—standard systems don’t always provide this by default.
