With a home battery, you can reduce your energy consumption by storing self-generated electricity and using it later when there is an energy demand. This allows you to be less dependent on the power grid and reduce energy costs.

How much you can reduce consumption depends on several factors, such as the capacity of the home battery, the amount of energy you generate yourself with solar panels, your energy consumption pattern, and the availability of sunlight.

For example, if you generate a lot of energy with your solar panels during the day but do not consume much energy at that time, you can store the excess energy in the home battery and use it later when you need more energy, such as in the evenings or on cloudy days. This can help to reduce your dependence on the power grid and lower costs.

The exact amount of consumption you can reduce varies depending on your specific situation. A home battery can be particularly useful if you have a large difference between energy generation and energy demand, for example, if you have many solar panels and consume little energy during the day. In such a situation, a home battery can significantly reduce your net energy consumption.

It is advisable to consult a professional solar energy specialist to get an accurate estimate of how much you can reduce your consumption with a home battery based on your specific situation, including the capacity of the battery and your energy generation and consumption pattern.
