Electrical energy storage installation with a usable capacity of min. 4.00 kWh – 1 unit. The subject of the order includes the application of an innovative energy management system EMS. This system is designed to manage electrical energy from the PV installations. It will be based on the use of a self-learning algorithm that recognizes conditions of energy fed into the grid from the PV installations and reacts to overproduction by activating additional loads in the facility. The system will have the ability to: measure energy consumed and fed into the electrical grid, connect loads in the facility that, in case of overproduction, may be activated to consume electrical energy within the facility, block the outflow of energy to the electrical grid. Self-learning algorithms, also known as machine learning algorithms, will significantly support the operation of the photovoltaic installation in a private home in several key areas: - Energy Production Forecasting: The algorithm can analyze historical weather data and current forecasts to more accurately predict the amount of energy that solar panels will be able to generate on a given day or week. - Monitoring and Fault Detection: The algorithm can monitor the performance of each panel and detect anomalies, such as reduced power, that may indicate a need for maintenance or repair. - Energy Storage Optimization: For homes with energy storage, the self-learning algorithm predicts the best time to charge and discharge batteries based on forecasted energy demand and solar energy production. - Energy Consumption Optimization: Working with an intelligent home management system, the algorithm can learn the energy consumption patterns of residents and suggest solutions to minimize energy consumption when production is low.
