The potential savings you can achieve with a home battery depend on various factors, such as your energy consumption, the size of the battery, the price of electricity, and your usage pattern. While the exact savings vary, there are several ways a home battery can help you save:

1. Self-consumption of solar energy: With a home battery, you can store excess energy generated by your solar panels and use it when you consume more electricity than your panels produce. This allows you to use more of your self-generated solar energy directly, rather than feeding it back into the electric grid at a lower rate. This increases your solar energy self-consumption and reduces your reliance on the electric grid.

2. Rate optimization: A home battery allows you to take advantage of rate structures where the price of electricity varies based on the time of day. You can charge your battery when electricity prices are low, such as at night, and use this energy during peak hours when electricity is more expensive. This can help you lower your energy costs by taking advantage of cheaper rates.

3. Backup power: A home battery can serve as a backup power supply during power outages. This means you don't need to rely on a generator or other emergency measures. It can save you costs and provide more convenience and comfort during power interruptions.

4. Grid stability and grid services: Some energy markets offer grid services and incentives to home battery owners. By making your battery available to the grid, for example during periods of high demand, you may potentially receive financial benefits.

The exact amount you can save with a home battery depends on your specific situation. To get a more accurate picture of the potential savings, I recommend contacting an authorized supplier or professional installer of home battery systems. They can assist you in calculating possible savings based on your energy consumption, rate structures, and local circumstances.
