What Phenogy does
Phenogy (legal entity PHENOGY AG, headquartered in Root D4, Switzerland) is a privately held developer and manufacturer of sodium-ion battery energy storage systems (BESS) for commercial, industrial, and critical-infrastructure customers. Its portfolio centers on the PHENOGY Series 1 platform for the EU market — available as the higher-capacity PHENOGY 1.0 and the modular, turnkey PHENOGY 1.1 (100 Ah, 50 kW nominal, 6,000+ cycle life, SMA SI50-20 inverter-integrated) — and the liquid-cooled PHENOGY 2.1 cabinet for U.S. deployments. The underlying technology is a proprietary sodium-ion cell chemistry (170 Ah at 2.85 V nominal) with operating range of −20 °C to +45 °C, reduced dependence on critical minerals such as lithium and cobalt, and TUV and CE certifications. Phenogy complements its storage hardware with PY.FLUX, a SiC-based Active Voltage Regulator for low-voltage grid optimization.
The company monetizes through direct enterprise sales of hardware — cabinets and containers sized and quoted per project — supported by regional sales coverage in Switzerland (HQ), the EU, the U.S., and APAC. It targets C&I customers for self-consumption optimization, peak shaving, backup power, EV charging support, and microgrids, and extends into critical-infrastructure (hospitals, water treatment) and grid-operator use cases. Manufacturing is anchored by PHENOGY Europe GmbH's facility near Bremen Airport — Europe's largest operational sodium-ion storage site at ~400 kW / ~1 MWh — and a planned 20,000 sq ft U.S. plant in Columbia, South Carolina via the CIBI partnership and a $10.2 million EDA grant, with production technology sourced through an exclusive worldwide license to Exentis Group's additive mass manufacturing platform and R&D supported by Fraunhofer ISIT, ETH Zurich, EMPA, and related European research partners. The company is backed by more than 500 private and institutional seed investors.

Phenogy product offering
Product offeringCore offering
Phenogy designs, manufactures, and sells sodium-ion battery energy storage systems (BESS) for commercial, industrial, and critical infrastructure customers. Its flagship products include the modular PHENOGY Series 1 (EU configuration) and PHENOGY 2.1 (US configuration) cabinets and containers, complemented by the PY.FLUX Active Voltage Regulator for low-voltage grid optimization.
Product overview
PHENOGY offers a portfolio of sodium-ion battery energy storage solutions for commercial, industrial, and critical infrastructure applications. The core product lines include the PHENOGY Series 1 (EU configuration) and PHENOGY 2.1 (US configuration) - both modular sodium-ion BESS systems available in cabinet and container form factors. The Series 1 encompasses two variants: PHENOGY 1.0 (high-capacity) and PHENOGY 1.1 (flexible/turnkey). Complementing the BESS products is PY.FLUX, a grid optimization module that functions as an Active Voltage Regulator using SiC-based power electronics to balance LV grid voltage and current. The portfolio supports applications including self-consumption optimization, peak shaving, backup power, EV charging infrastructure, and grid reinforcement.
