Industrial Outdoor IP54 Energy Storage Cabinet – 241kWh
GCB-E241 Industrial & Commercial Energy Storage Cabinet is a large-capacity high-voltage cabinet-type battery system designed for peak-valley arbitrage, demand management and backup power in C&I applications. It combines 15 battery modules of 16kWh each with one high-voltage control module in series, delivering a rated voltage of 768V, a nominal capacity of 241kWh, and 216.9kWh of usable energy at 90% depth of discharge, with a voltage range of 600~876V. It connects directly to three-phase high-voltage energy storage inverters without an external transformer.
At its core are 314Ah large-format LFP (lithium iron phosphate) cells with 157A continuous charge/discharge current, supporting a 0.5C rate — a full 241kWh charge or discharge in roughly two hours, well matched to daily peak-valley dispatch and demand management. The system achieves ≥90% system efficiency and a cycle life of over 6,000 cycles at 0.5C / 25℃ / 90% DOD, backed by a 10-year warranty for a lower levelized cost of energy over the whole service life.
Thermal management uses an air-conditioned active temperature control system (refrigeration, ventilation and heating). Together with an IP54 enclosure, it keeps the cabinet performing stably from -20℃ to 50℃ and at 0~95% humidity. An integrated fire-protection system provides cell-to-cabinet active safety and meets the safety access requirements of commercial and industrial sites.
The cabinet measures 1300×1260×2375mm and weighs 2500kg, with a compact floor-standing footprint. RS485 and CAN communication interfaces allow integration with mainstream inverters and EMS platforms for remote monitoring. The same cabinet platform supports a flexible 7–15 module configuration (112–241kWh), so customers can start with a smaller capacity and expand on site later without replacing the cabinet.
