Installation of GSL 10kWh Wall-Mounted Battery with Deye Inverter in an Italian Household

Italy, with its high solar irradiance and growing incentives for renewable energy adoption, has become a key market for home solar and storage systems. The homeowner, a family of four residing in a two-story house, had already installed a rooftop solar PV array with a capacity of 6kWp. However, without an energy storage system, most of the solar energy generated during the day was either wasted or fed back into the grid at low compensation rates. The family wanted to maximize self-consumption, reduce dependence on the grid, and secure power backup during outages.

Solution Overview
GSL Energy provided its high-performance 10kWh 51.2V 200Ah wall-mounted lithium battery (Model: GSL-051200A-B-GBP2), which is designed for residential solar storage applications. This model offers over 6,500 life cycles, IP65-rated waterproof design, WiFi monitoring, and a 10-year warranty, ensuring long-term value and peace of mind.

The battery supports up to 16 units in parallel, offering excellent scalability for future energy demands. To complete the system, a Deye hybrid inverter was integrated, which enables seamless solar energy conversion and intelligent energy management between solar panels, the battery, and household loads.

The installation was completed within a single working day. Thanks to the wall-mounted design and built-in handles, the battery was quickly and securely affixed to the garage, optimizing floor space. The system was configured using the Deye inverter’s smart interface and connected to the homeowner's WiFi for remote monitoring.

Customer Benefits

Increased Self-Consumption: The family is now able to store excess solar energy during the day and use it at night, increasing solar self-consumption from 35% to over 80%.

Backup Power Supply: During grid outages, the battery system provides reliable backup power, ensuring that critical household appliances such as lighting, refrigerators, and WiFi routers remain operational.

Cost Savings: By reducing grid electricity usage and avoiding peak-time tariffs, the family expects to save approximately €900 annually on energy bills.

Smart Monitoring: The system supports real-time performance tracking through both Deye and GSL’s cloud monitoring platforms, giving the user full control and transparency over their energy usage.
