Energy storage system
An energy storage system (ESS) is a solution that allows you to temporarily store electricity for later use. This is particularly useful if you generate energy using solar panels or wind, because production and consumption often do not occur at the same time. Basically, it works like this: the system stores surplus electricity in a battery and returns that energy as soon as you consume more than you generate or when the grid is unfavorable (or expensive). This increases your flexibility, reduces your dependence on the electricity grid, and allows you to use energy more intelligently.
