GSL High-Voltage Stacked Batteries Successfully Applied in Italy, Creating an Efficient Home Energy Solution

In a residential garage in Italy, GSL Energy successfully deployed a high-voltage stacked energy storage system consisting of five 15kVA high-voltage inverters and three sets of 30kWh high-voltage battery systems, with a total capacity of 90kWh, which can fully meet the energy needs of daily life and home office work.

Each 30 kWh battery system comprises 8 3.84 kWh LiFePO4 battery modules and 1 high-voltage control cabinet, adopting a stacked structure for flexible scalability and high-density integration. The entire system is connected to the grid and photovoltaic panels, enabling daytime charging and nighttime discharging, which significantly reduces reliance on the grid.

Based on actual electricity consumption patterns, the system can release over 60 kWh of electricity daily, potentially saving users over 21,000 kWh annually, equivalent to the total electricity consumption of an average Italian household over 7-8 years. Considering local electricity rates, this translates to annual savings of over €6,500 in electricity costs. If paired with a photovoltaic system for grid-connected power sales, additional revenue can be generated, enabling the system to recoup its investment in 3-4 years.

The system is installed in the user's garage, occupying only one wall, with neat wiring, a compact structure, space-saving design, stable operation, and attractive investment returns, making it an excellent example of residential energy storage applications in Europe today.

This project was provided with a comprehensive solution by GSL Energy. As a national high-tech enterprise established in 2011, GSL Energy specializes in the research, development, and manufacturing of lithium iron phosphate batteries, residential energy storage systems, and commercial and industrial energy storage systems. The company operates an automated factory (15,000㎡) with an annual production capacity of 5.8 GWh, and its products are exported to over 100 countries worldwide.

GSL products have obtained multiple international certifications, including UL9540, UL1973, CE, CB, UN38.3, and IEC62619, and the company offers OEM/ODM/OBM customization services to global clients, serving as a long-term partner for numerous overseas brands.
