GoodWe ESA CI0125K-04-00P All-in-One Storage System 125kW 261kWh LiFePO4
The GoodWe ESA 125kW / 261kWh (commercial code GW125/261-ESA-LCN-G10, item code CI0125K-04-00P) is an all-in-one storage system for commercial and industrial applications: PCS, batteries, BMS and EMS are integrated in a single outdoor cabinet. The storage section consists of 5 packs of 52.25kWh with 314Ah LiFePO4 cells, for a total of 261.25kWh of nominal and usable energy, with a nominal voltage of 832V and an operating range of 676-936V.
The PCS delivers 125kW nominal (up to 137.5kW at 400V) with a maximum efficiency of 98.6% and switching between charge and discharge in less than 60 ms. The system is scalable up to 20 units in parallel, equal to 2.5MW / 5.22 MWh. The battery packs are liquid cooled while the PCS uses intelligent ventilation; safety is entrusted to an aerosol + water suppression system, to explosion-proof fans and panels and to humidity monitoring at pack level with automatic dehumidification. The cabinet is IP54, operates from -25 to +55 °C and communicates via Modbus TCP and Modbus RTU.
