BESS 100-217-120 All-in-One Energy Storage System

Product Overview

The BESS 100-217-120 is an all-in-one hybrid energy storage system integrating a 217.03 kWh LFP battery pack and a three-phase hybrid inverter in a 2 m outdoor cabinet. It supports both grid-tied and off-grid operation with automatic transfer in under 10 ms.

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.
