[0001] Intelligent energy management system (iEMS_PV-S) for decentralized, location-independent photovoltaic systems (with and without inverters) and energy storage systems 3. Description of the invention

[0002] State of the Art: The current state of the art dictates that energy storage systems for photovoltaic (PV) applications require a direct, physical connection to the PV modules or their inverters. This coupling severely restricts the spatial arrangement of the components. It necessitates the proximity of the storage system and the PV array and complicates installation planning, as complex cable routes and drilling may be required. Furthermore, this fixed connection prevents independent scaling or the replacement of individual components without requiring a complete system reconfiguration.

[0003] Objective of the invention: The present invention aims to overcome the disadvantages of the prior art and to create an energy management system that enables spatial separation and autonomous communication between the PV system and the energy storage system.

[0004] Solution and advantages of the invention: The invention is an intelligent energy management system (iEMS) that enables decentralized control of energy flows in the home network. The system operates by continuously measuring the PV power output at the grid connection point and the total consumption of the home network. Both the PV system and the energy storage unit are connected without a direct physical connection, only via the home network.

[0005] A key advantage of the invention is the complete spatial independence of the components. The battery can be placed in any suitable location in the house, such as a cool basement room, without being limited by the reach of the PV or inverter cables. This significantly reduces installation effort and avoids cumbersome drilling or complex cable runs.

[0006] Another advantage lies in the modular design. Because the components are separate, they can be selected, expanded, or replaced independently, allowing for flexible scalability of the system.

[0007] The iEMS uses this decentralized arrangement to intelligently control energy flows: • In case of energy surplus: If PV production exceeds household consumption, the system regulates the charging of the storage unit. • In case of energy deficit: If household consumption exceeds PV production, the system initiates the feeding of energy from the storage into the household grid.

[0008] The threshold values ​​for this input and output are freely configurable, so that they can be optimally adapted to the performance data of the components, the individual consumption and the technical characteristics of the storage system (e.g. state of charge, total charge, charging cycles).
