Product Overview
The BESS-L 100D-217-120 is an AC-coupled all-in-one energy storage system integrating a 217.03 kWh LFP battery pack and a three-phase inverter in a 2 m outdoor cabinet. It supports grid-tied and off-grid operation with seamless 0 ms switching and up to 15 units in parallel.
The battery uses 314 Ah LFP cells in a 1P216S configuration with 691.2 V nominal voltage and 604.8-766.8 V operating range. Maximum charge and discharge current is 157 A. The inverter is available in 35 kW, 52 kW and 100 kW variants with 120/240 V (2P), 208/220/240 V (3P) and 380/400/415 V (3P) output options. A 7-inch resistive touch screen and aerosol fire suppression module are integrated.
