I wrote this article based on an analysis of Spanish electricity prices. Basically, buy electricity when it's cheap and use it when it's expensive. Instead of generating its own power, the battery acts like a smart storage tank. It charges from the grid during the midday slump when solar surplus makes electricity practically free. Then, during the expensive evening peak times, your house runs on the stored battery power instead of buying high-priced grid electricity.
