Residential Solar Energy Storage Success in Italy: GSL 10kWh Wall Battery + Deye Inverter

In early 2025, a family living near Florence, Italy, took a big step toward energy independence and sustainability. With the growing cost of electricity and increasing concerns about grid instability, they turned to solar power—but they didn’t stop at just installing panels. To maximize their investment and ensure a stable energy supply, they chose the GSL 10kWh wall-mounted LiFePO₄ battery paired with a Deye hybrid inverter.

This installation reflects a growing trend among Italian households: combining solar generation with advanced lithium battery storage to improve energy efficiency, reduce electricity bills, and minimize reliance on the grid.

The homeowner had previously installed a 6kW rooftop solar PV system. However, like many solar users, they found that a significant portion of the electricity generated during the day was going unused or being sent back to the grid for minimal compensation. Meanwhile, during evenings and cloudy days, they had to rely on grid electricity at peak rates. They needed a solution that could store their excess solar energy for use when they actually needed it.

The wall-mounted design of the GSL battery allowed for a neat, space-saving installation inside the home’s garage. The system was configured to charge the battery with solar power during the day and discharge in the evening and during peak-rate periods. The Deye hybrid inverter ensured smart energy flow and seamless switching between sources.
