Dual Guardians of Safety and Efficiency: Italian CEI 0-21 and CEI 0-16 Certifications
2026-01-30
The CEI 0-16 standard, formally titled "Rules for the Connection of Active and Passive Users to the LV and MV Electrical Utilities," primarily governs the technical requirements for connecting distributed generation systems (such as small-to-medium-scale PV and wind power) to the public grid. It defines permissible ranges for key parameters like voltage, frequency, and power factor, ensuring that user-generated power does not interfere with the stable operation of the public grid, thereby enabling safe grid integration.
