Pure Energy Storage Cabinet

Key Features
261kWh Liquid Cooling — High Energy Density Both models deliver 261kWh in a single outdoor cabinet with liquid cooling, maintaining stable performance across wide temperature ranges for 24/7 commercial operation.
Flexible PCS Integration ESA includes a built-in 125kW PCS (≥98.5% efficiency, power factor 0.99, THD <2%). ESL supports optional 30–125kW wall-mounted hybrid inverter — adapting to different project integration requirements.
Multi-Grid Compatibility Supports 50/60Hz, 230V/380V/400V three-phase AC (3L-N-PE) — compatible with European, Asian, and global grid standards.
Advanced Communication ESA uses Modbus TCP for SCADA/EMS integration; ESL adds 4G for remote monitoring without local network infrastructure.
Globally Certified ESA: IEC 62619, IEC 63056, IEC/EN 61000-6-2/-4, IEC/EN 62477-1, GB/T 36276. ESL: CE / UN38.3 / MSDS — covering major international markets and shipping regulations.
