Alpha ESS has launched its STORION-TB125 series BESS for large-scale C&I applications
This C&I BESS has a rated output power of up to 125 kW and stores up to 261 kWh of energy
The company also unveiled its STORION-H30/H50-G3 BESS for smaller C&I applications, which supports both on-grid and off-grid configurations
AlphaESS, a provider of PV inverters and storage solutions, has launched 2 new battery energy storage solutions (BESS) for commercial & industrial (C&I) applications.
The STORION-TB125 series BESS features a cabinet that houses battery units, power conversion systems, battery management systems (BMS), liquid cooling mechanism, and safety systems. It offers an output power (AC) of up to 125 kW and stores up to 261 kWh of energy. The BESS provides backup for up to a certain duration, which is based on its unspecified nominal charge/discharge rate, during grid outages or failures. Its capacity can also be expanded to up to 522.4 kWh by connecting 2 battery stacks in parallel. Moreover, for large megawatt-scale projects, up to 50 BESSs can be connected in parallel. The system supports multiple energy sources, like solar power, diesel generators, and EV chargers, through an AC coupling configuration.
The BESS’s operational temperature is controlled by a continuous circulation of liquid coolant. This feature maintains the cell-to-cell temperature delta under 3°C, which supports consistent operation in warm C&I environments or during heavy cycling (charge/discharge).
For C&I prosumers who require storage but do not have the space or energy demand to justify a liquid-cooled system, the company launched the H30/H50-G3 series BESS. Instead of separating the batteries, inverters and controls across multiple housings, this model places everything in a single enclosure. It is available in 30 kW and 50 kW options, with storage capacity reaching up to 241 kWh per cabinet, depending on configuration. Its potential for capacity expansion differs according to the system configuration. For a grid-connected configuration, the capacity is expandable to a power output of up to 500 kW and a storage capacity of up to 2.41 MWh by connecting up to 10 cabinets in parallel. However, its power output and storage capacity expansion limit are lower in off-grid configuration: 200 kW and 964 kWh (up to 4 cabinets in parallel), respectively.
Unlike the former product, which relies on liquid cooling to manage heat, it uses insulation and multilayer BMS-based protection to manage thermal safety. According to the company, this solution fits well for users such as retail chains, farms, workshops, commercial buildings and hospitality businesses that want storage for peak-shaving, backup and energy optimization rather than long-duration industrial output.
The company’s press release didn’t include commercialization details for these products.
