The household has sufficient rooftop solar power generation during the day, but still needs to purchase electricity from the grid at night. At the same time, they hope to have a backup power source to meet their basic electricity needs in case of a power outage at home. The project team installed a white household battery energy storage system on the garage wall, which operates in conjunction with the existing rooftop solar system.
After system installation, photovoltaic power generation during the day will prioritize supplying daily household electricity, and excess electricity will be automatically stored in energy storage batteries; During the peak hours of nighttime electricity consumption, batteries release electricity to supplement household electricity demand, effectively reducing dependence on the power grid. In the event of a power outage, the energy storage system automatically switches to the backup power supply mode to ensure the normal operation of equipment such as refrigerators, lighting, and network communication.
The user feedback shows that the entire installation process was clean and tidy, the equipment took up little wall space, the appearance was simple and elegant, and coordinated with the garage environment. You can check the battery level, charging and discharging status, and saved electricity costs at any time through the mobile app. After installation, the monthly electricity expenses have been further reduced, and users have significantly improved their autonomy and sense of security in using electricity.
