This system adopts a DC-coupling architecture and anti-backflow design, integrating energy management system (EMS), bidirectional inversion, MPPT PV control, and a high-precision Battery Management System (BMS). It is equipped with long-cycle LFP batteries to form an integrated energy storage unit. The system executes the intelligent energy scheduling strategy on a 24-hour cycle: solar power is prioritized for on-site consumption, with surplus energy stored. During insufficient sunlight or high electricity prices, the battery discharges to support the load, achieving "self-generation and self-consumption, surplus storage." Additionally, the system features virtual power plant (VPP) node functionality, enabling remote response to grid dispatch and participation in services such as peak shaving demand response. In the event of grid anomalies, it can switch to off-grid mode to ensure local power supply. Through the coordinated operation of generation, storage, consumption, and grid interaction, the system ultimately delivers 3 core values: improved energy economics, enhanced power reliability, and support for grid stability—providing users with an efficient, flexible, and resilient green energy solution.
