Core Features Residential & small C&I
01

High capacity, safer chemistry

314 Ah LiFePO₄ cells in a 16S2P configuration — 32.15 kWh per unit at 51.2 Vdc. Stable chemistry with excellent thermal stability, 100% depth of discharge and ≥8,000 cycles. The built-in intelligent BMS guards against over-charge, over-discharge, over-temperature and short circuit.

02

Floor-standing by design

Steel floor-standing tower — set it down, connect it, done: no wall bracket and no rack cabinet required. A built-in circuit breaker provides electrical isolation.

03

Smart and connected

An optional external Wi-Fi module streams data to the Gobel VRM monitoring platform, and the battery integrates with Home Assistant and ioBroker. RS485A/CAN to the inverter plus RS485B/RS485C for parallel runs.
