The system wiring diagram illustrates how the 126kW/215kWh BESS connects seamlessly with solar PV, the utility grid, and AC loads to form a complete hybrid power solution. Solar panels deliver DC energy to the PCS, which converts and distributes power to charge the 215kWh LiFePO4 battery pack or supply electricity directly to the load. During grid outages or peak demand, the PCS automatically discharges from the battery to ensure stable and uninterrupted power. When solar generation is insufficient, the system draws energy from the grid. The integrated BMS and EMS work together to manage protection, power flow, and energy optimization across all components. This layout provides a clear understanding of the system’s operating structure and energy pathways.
