FOX ESS - Battery T-MAX PLUS 241kWh-125kW-HYB

The Fox ESS T-MAX PLUS 241 kWh – 125 kW HYB energy storage system is an all-in-one containerized solution for commercial and industrial applications seeking increased energy autonomy and optimized power flow management. This hybrid system integrates a long-life LFP battery, a 125 kW power converter (PCS), an intelligent battery management system (BMS), a preventative safety device, and a liquid cooling heat dissipation system, all within a standardized container.

The usable capacity of 241 kWh meets the needs of commercial and industrial sites with high energy consumption or those wishing to utilize existing photovoltaic production. The 125 kW power output provides a charge and discharge capacity suitable for peak consumption or load shedding operations.

The system supports direct grid connection, photovoltaic installations, backup power supplies, and generators. Switching time between grid and off-grid modes is less than 10 ms , ensuring continuity of service for critical applications. The modular architecture allows for expansion via parallel connections to adapt capacity to site changes.

The round-trip efficiency reaches 90% , limiting energy losses during charge-discharge cycles. The LFP battery ensures a lifespan of over 8,000 cycles at 70% depth of discharge, reducing the total cost of ownership over its operating life.
