DEIF
2025 editionOur portfolio includes green energy control solutions that enable you to design, deploy, and operate hybrid microgrids (PMS and EMS) and control/protection solutions for energy generation and storage units (fuel cells, fuel cell generators, gas engines, gas generators, diesel generators, steam-gas-hydro turbines, and wind turbines, electrolyzers, and BESS). We offer turnkey solutions, as well as dedicated and programmable controllers (Codesys or C languages).
In 2025, DEIF expanded its product portfolio with a new series of power converters for onshore and marine applications.
These new power converters are based on silicon carbide, which gives them higher efficiency and a much smaller installation footprint than solutions based solely on silicon.
With a presence in more than 50 markets worldwide, we help you get the most out of your investment and maximize the adoption of green energy through consulting, training, support, and value-added services.
