Product Overview
The AEGIS CI-522 is a 522kWh commercial and industrial energy storage system designed for factories, commercial complexes, telecom infrastructure, and large-scale solar-plus-storage projects.
With 250kW continuous output power and 522kWh of stored energy, this system delivers serious capacity for commercial peak shaving, demand charge reduction, backup power, and solar self-consumption optimization. The air-cooled design keeps maintenance costs low while delivering reliable performance across a wide temperature range.
Every rack integrates its own BMS module, while a system-level BMS coordinates across all racks for optimal charge/discharge balancing. Remote monitoring via EMS cloud platform provides real-time visibility into system health, SOC, temperature, and alarm status.
Built with Grade A LiFePO4 cells from our own production line, the CI-522 is backed by our 10-year product warranty and dedicated C&I after-sales engineering support.
On-site commissioning support available for large projects
Our engineering team provides remote or on-site installation guidance for C&I deployments
