Energy storage installation with useful capacity of at least 4.00 kWh – 1 pcs. The subject of the order includes the implementation of an innovative EMS energy management system. This system is designed to manage electrical energy from the PV installations. It will be based on a self-learning algorithm that recognizes situations of energy delivery to the grid from the PV installations and responds to overproduction by engaging additional loads in the facility. The system will have the capability to: measure energy consumption and injection into the power grid, connect loads in the facility that can be engaged in case of overproduction for energy consumption in the facility, block energy outflow to the power 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 predict the amount of energy that the photovoltaic 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 abnormalities, such as power drops, that may indicate the need for maintenance or repair. - Energy Storage Optimization: In the case of homes with energy storage, the self-learning algorithm predicts when it is best to charge and discharge the batteries based on expected energy demand and solar energy production. - Energy Consumption Optimization: Working with an intelligent home management system, the algorithm can learn the patterns of energy consumption of the residents and propose solutions to minimize energy consumption when production is low.
