Powering an Italian Villa: Triple GSL 10kWh Wall Batteries with Dual Deye Inverters for Ultimate Energy Independence

The batteries were mounted side-by-side along a clean interior wall in a dedicated business room, with sufficient spacing for ventilation and maintenance. Each unit was carefully wired to ensure balanced charging and discharging, and all battery management systems (BMS) were synchronized. The two Deye inverters were installed directly above the battery units, providing a tidy and compact layout. The inverters manage two separate PV strings, each connected to a portion of the rooftop solar array, maximizing solar harvest throughout the day.

Key installation highlights:
Efficient cable routing, minimizing energy loss
Clean wall-mounted configuration, space-saving and visually tidy
High system integration, ready for smart grid interaction

Производительность & Advantages
After commissioning, the homeowner immediately experienced several key benefits:
Extended Runtime – With 30kWh of energy storage, the villa can run entirely off-grid for extended hours, even during cloudy days.
Load Segmentation – With dual inverters, critical appliances and high-demand devices (like EV chargers and heating) are managed separately for better efficiency.
Grid Interaction – The system allows exporting excess power to the grid during peak solar production and importing during low tariff periods.
Seamless Backup – In the event of a power outage, the system instantly switches to backup mode, keeping essential appliances running.
