This green smart house with photovoltaic storage, which is a mobile house in a packing box, is the core exhibit of the "Green Construction and Smart Energy Integrated Solutions" area in the factory exhibition hall. It deeply integrates photovoltaic tiles, energy storage cabinets, air energy, intelligent power distribution and box-type fast-installation structure, and demonstrates on-site how to complete the hoisting within 72 hours and achieve zero-carbon occupancy within 48 hours. Through real-time calculation of sunshine curves, household loads, and peak and valley electricity prices, the audience can intuitively see the complete closed loop of rooftop photovoltaic power generation and use, surplus power storage, and emergency off-grid, verifying the factory's system integration capabilities in the three major sectors of modular construction, distributed energy and Internet of Things control, thereby providing a replicable zero-carbon fast-construction model for real estate camps, rural revitalization, emergency resettlement and other projects.
