Phenogy modular sodium-ion storage targets commercial and industrial energy needs with a flexible new battery system for 2026. The Swiss company introduced Phenogy 1.1 at The smarter E Europe trade show in Munich, Germany. Moreover, the launch builds on Phenogy’s earlier deployment of a 1 MWh sodium-ion energy storage system near Bremen Airport in Germany.
Phenogy modular sodium-ion storage for C&I applications
Phenogy designed the new system for commercial and industrial users that need scalable energy storage. It supports several important use cases. For example, operators can use it for peak shaving to reduce demand charges. In addition, facilities can rely on it for backup power and UPS functions. The system also supports EV charging through load buffering. Furthermore, users can store lower-cost renewable electricity and dispatch it when market prices rise.
The modular design improves flexibility. As a result, businesses can match storage capacity to site requirements more easily. This approach also helps facility operators integrate storage into different energy strategies without major redesigns.
Phenogy modular sodium-ion storage system specifications
Phenogy 1.1 combines compact dimensions with industrial-grade power features. The unit measures 2,200 mm x 1,120 mm x 2,015 mm. It weighs 2,580 kg. In addition, it offers a nominal capacity of 100 Ah and a nominal power of 50 kW. The system uses a rated grid voltage of 400 V and a rated grid frequency of 50 Hz.
At the battery cell level, Phenogy uses sodium-ion chemistry with a rated capacity of 170 Ah per cell. Each cell has a nominal voltage of 2.85 V. The battery configuration is 1P208S. Therefore, the system delivers a nominal DC voltage of 592 VDC. Its operating voltage range spans from 374 VDC to 718 VDC. The company rates the system for at least 6,000 cycles under specified operating conditions. Consequently, the product fits long-term commercial operation.
Phenogy modular sodium-ion storage installation and protection
Phenogy built the system for real-world industrial environments. It supports installation at altitudes up to 2,000 m. It also carries an IP54 protection rating. Therefore, the enclosure offers protection suitable for demanding indoor and selected sheltered outdoor conditions.
The thermal management system uses air cooling. In addition, Phenogy integrated several safety features into the architecture. These include gas sensors, heat sensors, smoke detection, and aerosol-based fire suppression. The company says this combination supports strong thermal performance and reliable operation. It also says the battery cells offer increased thermal stability, which works well with the air-cooling design.
The system also operates across a broad temperature range. As a result, it can maintain stable performance in winter and summer conditions. This feature supports dependable performance during peak demand periods and overnight cycling.
Phenogy modular sodium-ion storage and energy management
Phenogy equipped the system for integration into solar and energy management setups. It uses the SI50-20 inverter from German manufacturer SMA as its main communication interface. Through the SMA Data Manager, the system supports Ethernet, Modbus TCP, and RS485 communication protocols.
These interfaces improve interoperability. For example, aggregators and facility operators can use them for centralized control. Likewise, the system enables structured data exchange with higher-level energy management platforms. It also supports compatibility with grid operator interfaces. Therefore, businesses can connect the storage platform more smoothly to existing energy infrastructure.
Phenogy modular sodium-ion storage compliance standards
Phenogy states that the system meets several important international standards. These include IEC 62619, IEC 62477, and IEC 63056 for battery safety and power conversion systems. In addition, it complies with IEC 61000-6-2 and IEC 61000-6-4 for electromagnetic compatibility. Consequently, the product aligns with key technical and safety requirements for commercial deployment.
Why Phenogy modular sodium-ion storage stands out in 2026
Phenogy positions this new platform as a practical option for businesses that need modular storage with broad functionality. The system combines 50 kW nominal power, scalable deployment potential, and at least 6,000 cycles. Moreover, it supports peak shaving, backup power, EV charging support, and energy arbitrage in one platform.
The launch also strengthens Phenogy’s position in Sodium-ion Battery storage for commercial and industrial applications in 2026. By pairing modular architecture with industrial communications and integrated safety systems, the company has created a storage solution that addresses performance, control, and operational reliability in one package.
