The right battery capacity is best chosen based on your consumption, your solar panels, and what you want to achieve with your installation. Those who primarily want to use more of their own solar energy often find a smaller battery sufficient. Those who also want to manage peaks, be less dependent on the grid, or want extra security during power outages are better off choosing a larger capacity. <\/p>\n

In practice, there is no standard answer. A battery that is too small will not utilize your full potential. A battery that is too large will offer a lower return. That is why we always look at your specific situation and advise a solution that ensures the best long-term return.
