en.Wedoany.com Reported - Swiss sodium-ion battery supplier Phenogy has launched a modular energy storage solution for commercial and industrial (C&I) applications, named Phenogy 1.1, at the Smarter E trade fair in Munich, Germany. This product follows the company's deployment of a 1 MWh island-operated sodium-ion energy storage system near Bremen Airport in Germany.
Phenogy describes this energy storage system as flexible and modular in design, enabling scalable capacity configurations suitable for peak shaving to reduce demand charges and operating costs, critical infrastructure backup power and UPS functions, electric vehicle charging load buffering, and storing low-cost renewable energy for dispatch during peak electricity prices for energy arbitrage. The new product measures 2200 mm x 1120 mm x 2015 mm, weighs 2580 kg, with a rated capacity of 100 Ah, rated power of 50 kW, rated grid voltage of 400 V, and rated frequency of 50 Hz.
The system supports installation at altitudes up to 2000 m, with an IP54 protection rating, air-cooled thermal management, and an integrated safety architecture including gas sensors, thermal sensors, smoke detectors, and an aerosol-based fire suppression system. At the cell level, it uses sodium-ion chemistry, with each cell having a rated capacity of 170 Ah and a nominal voltage of 2.85 V. The battery configuration is 1P208S, with a nominal DC system voltage of 592 VDC, an operating voltage range of 374–718 VDC, and a cycle life of at least 6000 cycles under specified operating conditions.
For integration into existing solar installations and energy management environments, the system uses the SI50-20 inverter from German manufacturer SMA as the primary communication interface. Through the SMA Data Manager, the Phenogy 1.1 supports standard industrial communication protocols such as Ethernet, Modbus TCP, and RS485, enabling centralized control for aggregators and facility operators, and ensuring compatibility with higher-level energy management systems and grid operator interfaces. Phenogy states that the key differentiators of the new system are safety and thermal performance, achieved through a safer system design, active monitoring, and intelligent protection mechanisms to avoid risks such as overheating. The higher thermal stability of the battery cells makes it suitable for air-cooled applications. The system operates over a wide temperature range, maintaining stable performance under both low winter temperatures and high summer temperatures, supporting reliable operation during peak demand periods and nighttime cycles. In terms of compliance, the system meets IEC 62619, IEC 62477, and IEC 63056 standards for battery safety and power conversion systems, as well as IEC 61000-6-2 and IEC 61000-6-4 standards for electromagnetic compatibility.
