In the innovative application of "photovoltaic+energy storage", household solar energy storage solutions have emerged. Photovoltaic inverters convert solar energy, a renewable energy source, into electrical energy, and the integrated photovoltaic and energy storage machine supplies this electrical energy into the household power system, helping to optimize household energy management. The "energy storage" function can ensure normal household electricity consumption in the event of power outages or instability in the power grid, improve electricity safety and stability, and provide uninterrupted power protection for households. Meanwhile, the supply of electricity through new energy sources can save household electricity expenses and empower green, low-carbon new lifestyles.
