Product Details
The Energic IEB350kWh is a 350kWh all-in-one liquid-cooled energy storage system designed for commercial & industrial facilities, construction sites, oilfields, weak-grid environments, and high-power demand applications.
The system integrates 350kWh of battery energy storage, 350kW AC power conversion, dual liquid-cooling thermal management, intelligent energy management, and optional PV integration into a single self-contained unit.
Commercial & Industrial Energy Storage The IEB350kWh enables peak load shifting, demand-side management, dynamic power expansion, and intelligent C&I energy management to optimize electricity costs and reduce grid demand charges.
Construction Site Power Backup Designed for weak/no-grid environments, construction sites, oilfields, and temporary power projects, the system delivers plug-and-play backup power with automatic on-grid/off-grid operation.
Battery Energy Storage Architecture The system incorporates two 175kWh liquid-cooled battery clusters (350kWh total capacity) operating at 614.4V nominal voltage (537.6–691.2V operating range) with 285Ah capacity. Battery safety and performance are monitored by a two-level BMS architecture (Battery Pack BSU + High-Voltage Control Box BMU).
High-Power Discharging & Thermal Management Delivers 350kW maximum AC power and up to 420kW short-duration discharging power for 1 minute (420kW max battery power). Thermal control is maintained by two liquid-cooling units, each featuring 8kW refrigeration capacity and 2.5kW heating capacity.
Solar PV & On-Grid / Off-Grid Switching Supports 2 PV access channels for up to 80kW PV access, integrating solar generation with battery storage. Features automatic and manual on-grid/off-grid control with isolated three-phase + neutral operation. The optional 250kVA / 500kVA Static Transfer Switch (STS) provides ultra-fast 20ms switching time with 99.5% efficiency.
EMS, HMI & Safety Systems Equipped with IMMU2 local EMS supporting Ethernet, 4G, Wi-Fi, WLAN, LAN, Modbus, IEC 104, IEC 61850, MQTT, and WebSocket protocols. The HMI includes a 10-inch TFT touchscreen, 5 status LEDs, emergency stop, and battery fire alarm light/beeper. Multi-layered safety includes anti-reverse protection, insulation detection, aerosol fire extinguishing, water-fire interface, smoke detection, combustible-gas detection, temperature/humidity/door monitoring, emergency fan, explosion-proof board, and fire-propagation-resistant structure.
