Cefem Group

What Cefem Group does

Cefem Group is a French family-owned (100%) industrial manufacturer founded in 1987, operating through three business divisions: CEFEM Power (passive components for power electronics including transformers, inductors, and film capacitors), CEFEM Process (industrial safety switchgear and continuous inline measurement devices), and CEFEM Solar (photovoltaic inverters and, via the ECO-SYST subsidiary, turnkey solar power plant installation and monitoring). The group maintains 7 production sites across France, Romania, and India and operates direct enterprise sales coverage in France and through CEFEM USA Inc. in Philadelphia, serving industrial equipment manufacturers, heavy-industry operators, and solar project developers in B2B channels.

The product portfolio includes proprietary technologies such as the CRONOS II connected power capacitor with embedded electronics for remaining-life prediction (developed with CEA-LETI and ESISAR), the NIRLED contactless inline near-infrared moisture sensor, the Trio-Sun three-phase PV inverter family, ICV visible-break industrial safety switches, and 30kW dynamic wireless EV charging couplers developed for the EU INCIT-EV project with VEDECOM. The Cefemportal platform provides remote supervision and defect detection for deployed photovoltaic systems, while EDIT/NIR instrumentation supports real-time industrial process measurement.

The business model is direct B2B hardware sales of customized electrical and energy components, supplemented by professional services for solar installation (engineering, installation, maintenance). Pricing is quote-based and tailored to OEM specifications rather than list-based, with revenue distributed across multiple verticals including UPS, railway, electrification, automotive, cement/heavy industry, and solar developers. CEFEM has executed a multi-decade M&A program (SCR 2014, Transrail 2016, Edit Laser 2017, ECO-SYST 2022) to extend capability and geographic reach, while remaining 100% family-owned with no external funding rounds disclosed.

Core offering

Cefem Group designs and manufactures electrical and energy solutions through three business units: CEFEM Power produces passive components for power electronics (transformers, inductors, film capacitors), CEFEM Process manufactures industrial safety switchgear and continuous measurement devices, and CEFEM Solar builds photovoltaic inverters and installs solar power plants. The group sells custom-engineered hardware directly to industrial equipment manufacturers, heavy industry operators, and solar project developers.

Product overview

Cefem Group is a multi-division technology company comprising CEFEM Power (passive components for power electronics), CEFEM Process (safety enclosures and measurement devices for industrial sites), and CEFEM Solar (photovoltaic inverters and solar monitoring solutions). The group's CEFEM Solar division offers products including Trio-Sun inverters, CRONOS II, ECOSYST management system, and the Cefemportal monitoring interface. CEFEM Process provides EDIT measurement instruments and NIRLED measurement devices. CEFEM Power supplies SCR condensers and related power quality components. The divisions operate as distinct business units under the unified Cefem Group umbrella, serving industrial, energy, and process safety markets.
