Energy storage system – FoxESS – TM241KWH-125KW-H
Product details
T-MAX PLUS
T-MAX PLUS is an energy storage system for commercial and industrial applications, combining an LFP battery, a battery management system (BMS), a power conversion system (PCS), and protection systems in a single enclosure. It supports direct connection of a photovoltaic installation, the power grid, backup power loads, and a generator. Designed for outdoor installation, it also integrates power distribution and heat dissipation management.
Key advantages of T-MAX PLUS
- Battery system capacity 241 kWh and rated AC output power of 50–125 kW, depending on the model. The maximum PV input power is 100–250 kW.
- Grid and off-grid power supply with a switching time of less than 10 ms and diesel generator support.
- Energy flow management includes peak load reduction, grid load relief, management of photovoltaic and stored energy, and frequency regulation.
- Liquid cooling and temperature control using 128 sensors. The stated cycle life is at least 8000 cycles with 70% capacity at the end of service life.
- Safety and fire protection include arc detection, smoke and heat sensors, an alarm indicator, and aerosol fire suppression at cabinet and pack level. The enclosure has an IP55 protection rating, and the battery pack IP67.
- Expandable through parallel connection and factory configuration that simplifies on-site commissioning. Operating data can be transmitted to the Fox ESS cloud via Wi-Fi, 4G or 5G.
Who is this a good choice for?
T-MAX PLUS is designed for businesses and industrial facilities requiring energy storage and integration of photovoltaics, the grid and a generator. Companies managing peak power demand can benefit from load reduction and PV energy management, while users requiring backup power can benefit from off-grid operation and switching in under 10 ms. Parallel connection capability meets the needs of organizations planning to expand their system.
