Project Location: Poland
Application: Outdoor Solar + Battery Energy Storage System (BESS)
In 2026, GSL Energy successfully deployed a 60kWh High Voltage All-in-One Energy Storage System in Poland. The system was installed outdoors to support a hybrid solar + storage application designed for peak shaving, backup power, and energy cost optimization under Poland’s evolving electricity market conditions.
This case demonstrates a reliable, weather-resistant, and grid-compliant high voltage ESS solution tailored for European outdoor environments.
The 60kWh system was installed on a reinforced concrete base in an open outdoor area adjacent to the PV array. The cabinet features an IP65-rated waterproof and dustproof enclosure, engineered to withstand:
Rain and snow exposure
Low winter temperatures in Central Europe
Wind and environmental corrosion
Long-term outdoor UV exposure
The integrated all-in-one structure combines battery modules, BMS, power distribution, and system protection within a single compact cabinet, significantly reducing installation time and wiring complexity.
System Type: High Voltage All-in-One Energy Storage System
Capacity: 60kWh
Battery Chemistry: LiFePO4 (Lithium Iron Phosphate)
Installation Mode: Outdoor Ground-Mounted
Protection Level: IP65 Waterproof
Application: Residential & Light Commercial Solar + Storage
Functionality: Peak shaving, backup power, self-consumption optimization
The high-voltage architecture improves overall system efficiency by reducing current losses and enhancing inverter compatibility for European grid standards.
The project was delivered by certified installation engineers with European grid-connection experience. The commissioning process included:
Grounding and lightning protection integration
Waterproof sealing verification
BMS parameter calibration
