Enphase’s ferrite ring prevents interference in the communication between the Enphase microinverters and the IQ gateway (Envoy) and protects your equipment’s sensitive electronic control system. The ENP ferrite ring measures 41.8 x 26.2 x 12.5mm.
The ferrite ring must be carefully installed above the power cables. It is important to do this correctly to prevent damage to the electronic control system. Do not install the ferrite ring on the outside of the electrical enclosure and make sure all the cables pass through the centre of the ferrite ring before you close it.
Use four rings if you have a three-phase system and two rings if you have a single-phase system.
