261kWh liquid-cooling cabinet system for scalable C&I energy storage projects.
MEGAESSOSR261K Scaleup C&I Energy Storage Solution
A modular commercial and industrial energy storage solution based on the MEGAESSOSR261K all-in-one liquid-cooling cabinet. The system combines hybrid-electrolyte solid-state LFP cells, 5S intelligent management and flexible BCP-based expansion to support peak shaving, self-consumption optimization, backup power and multi-market energy operation.
Application Scenarios

Peak shaving and demand control
Regulates load peaks, reduces demand charges and improves commercial energy economics.

PV-plus-storage self-consumption
Stores surplus photovoltaic energy and releases it during high-price or low-generation periods.

Backup power for key loads
Provides backup supply for critical loads during unexpected grid outages.

Energy trading and multi-market operation
Supports market-oriented operation including control power, co-location and marketer scheduling.
Scalable C&I energy storage built around MEGAESSOSR261K
MEGAESSOSR261K Scaleup is designed for commercial and industrial projects that need a future-proof battery energy storage system with high safety, reliable lifecycle management and flexible capacity growth. Each cabinet provides 261kWh nominal storage capacity and uses advanced Hybrid Electrolyte Solid State LFP 314Ah cells for long service life, high efficiency and robust operational safety.
The all-in-one architecture integrates the core 5S system: EMS, BMS, PCS, TMS and SMS. This enables coordinated control of charging and discharging, thermal management, battery protection, safety monitoring and cloud-based operation from one compact outdoor cabinet.
Modular scaleup architecture
The solution uses a Busbar Cabinet (BCP) to concentrate and distribute electrical energy across multiple storage cabinets. The BCP supports energy storage system connection, power distribution, real-time monitoring, protection and system expansion. Multiple cabinets can be installed side by side, allowing the project to increase storage capacity as demand grows while keeping the system maintainable and easy to operate.
Project value
For industrial parks, charging infrastructure, commercial buildings and distributed energy projects, the system supports peak and valley arbitrage, demand control, demand-side response, backup power supply, self-consumption optimization and energy trading. Megalion also supports the full project lifecycle, from design freeze and material preparation through implementation, monitoring, maintenance and service operation.
