BESS 60-126-75 All-in-One Energy Storage System

Product Overview

The BESS 60-126-75 is an all-in-one hybrid energy storage system integrating a 126.6 kWh LFP battery pack and a three-phase hybrid inverter in a compact 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 1P126S configuration with 403 V nominal voltage and 352.8-447.3 V operating range. Maximum charge and discharge current is 157 A. The inverter is available in 21 kW, 31 kW and 60 kW variants with 120/240 V (2P), 208/220/240 V (3P) and 380/400/415 V (3P) output options.
