Reliable protection despite increasing disturbances

Comprehensive monitoring for total control

Efficient energy distribution

Feeding in energy from renewable sources causes increased loads in the distribution network. EFEN’s complete product range serves as the backbone for systematic collection and monitoring of all energy efficiency data. Our end-to-end solutions cover the entire process, from power generation, storage and power distribution.

Reliable protection despite increasing disturbances

The number of decentralized providers of energy  generated by wind farms, solar or biogas plants is steadily increasing, thereby impairing grid quality. In addition to the bidirectional flow of energy, harmonics have turned out to be a factor of significant effect. Thanks to the extensive engineering know-how, EFEN considers these implications for all solutions offered.
