The growing adoption of photovoltaic systems in the residential sector creates a demand for control systems capable of coordinating energy production, consumption, and storage. This thesis therefore addresses the design and implementation of a Home Energy Management System (HEMS) aimed at optimizing energy utilization from a photovoltaic installation with battery storage. As a foundation for the design, the principles of energy management, communication protocols of photovoltaic inverters, and available commer- cial HEMS solutions were analyzed. A common limitation of existing solutions is their closed architecture with no possibility of customization. The proposed architecture divides control responsibilities between a local microcontroller and a cloud platform, where the local unit handles inverter communication via Modbus TCP/IP and the cloud computes the optimal control schedule. The firmware running on the ESP32-S3 platform in ESP-IDF is structured into nine modular components communicating through FreeRTOS queues. The key contribution is a modular inverter driver that allows additional models to be supported without modifying the application logic, a driver for the GoodWe hybrid inverter of the ET series was implemented as part of this work. The system was veri- fied on a real installation with a GoodWe GW10K-ET inverter and a 10.6 kWh battery storage, confirming its readiness for deployment in a real-world environment.
