Residential Energy Storage Systems (RESS)
Residential Energy Storage Systems, often referred to as household or home energy storage systems, are designed to store electricity for home use. These systems consist of batteries combined with a power conversion system, allowing you to store energy from various sources such as solar panels, wind turbines, the public grid, or other energy generators. The primary purpose of these installations is to improve the efficiency of home power systems, reduce electricity costs, and provide an uninterruptible, reliable power supply. Energy surpluses generated during the day can be stored and used in the evening or during grid outages, reducing dependency on the electricity grid. New applications, such as participation in a Virtual Power Plant (VPP), can further increase the profitability of residential systems.
How does a Residential Energy Storage System work?
We can imagine home energy storage system as a rechargeable battery used for example in your phone, computer or car. Electricity produced from various sources like solar panels, wind turbines or other power generators is being used to charge the battery in form of direct current (DC).
To make it available for most household appliances, the energy is later transformed via power conversion system into alternating current (AC), used by most electronic devices at home. The primary source of energy to charge the batteries is surplus energy generated during high-production and low-demand periods.
Intelligent Energy Management Systems (EMS) take care of monitoring whole household and optimizing power distribution and use by using the desired pre-defined programs. The excess energy can also be sold back to the grid in periods of higher price on the market.
