EGS120 Liquid-Cooled Integrated Photovoltaic-Storage System

The EGS120 Battery Energy Storage System adopts an all-in-one design philosophy, integrating the PV system, long-life battery cells, an efficient bidirectional balancing BMS, a high-performance PCS, a fire protection system, an intelligent power distribution system, and a thermal management system into a single cabinet. This enables safe, stable, and reliable long-term operation while achieving flexible capacity deployment of the energy storage station through AC-side grid connection.

Enhanced Safety

Dual-level fire protection at both the PACK and system levels. High-reliability electrical components with four layers of protection ensure maximum operational safety.

Flexible Configuration

Modular solar-storage-diesel integrated solution. Features 4-channel MPPT with up to 40A string current support. Supports multi-unit parallel operation and distributed deployment.

Intelligent & Efficient

High energy density and excellent charge/discharge efficiency. Real-time remote monitoring and control through EMS optimization. Supports peak shaving, valley filling, and intelligent power distribution.
