Exide Technologies has introduced a new 5 MWh battery energy storage system (BESS) designed for utility-scale and commercial-industrial (C&I) applications across Europe. The system, called Solition Mega Five, fits into a standard 20-foot container, marking the company’s entry into the high-capacity modular storage segment.
The liquid-cooled lithium-iron-phosphate (LFP) system aims to support grid balancing, peak shaving, and renewable integration, offering high energy density in a compact format. Exide said the unit is suitable for both front-of-meter and behind-the-meter setups, including microgrids and industrial sites that need backup or load-management capabilities.
The containerized unit comes pre-assembled with inverters, transformers, and medium-voltage switchgear, allowing faster on-site installation. Its modular design enables system scaling to meet project-specific requirements, while the integrated battery management system (BMS) handles diagnostics, safety, and performance optimization.
The company reports an operational efficiency of around 95%, achieved through its liquid-cooling architecture, which helps maintain battery temperature and extend cycle life. Safety systems include multiple layers of protection and remote monitoring features.
The launch of the Solition Mega Five aligns with Europe’s growing demand for energy-storage solutions as the region increases its share of renewable generation and faces rising grid-stability challenges. The market is also shifting toward mid-sized, factory-assembled storage products that can be deployed quickly without complex permitting processes.
Industry analysts note that compact, modular systems like this are increasingly being adopted by energy developers, utilities, and large industrial users to stabilize power supply and optimize electricity costs. With its 5 MWh format, Exide’s system fills the gap between smaller on-site batteries and large utility-scale installations.
The system is expected to serve multiple use cases, including frequency regulation, energy trading, self-consumption, and off-grid backup, reflecting the broader European shift toward flexible, distributed energy infrastructure.
