Installing EMI line lter with IQ Gateway
The EMI line lter is required for installations in Europe with the IQ Gateway (Standard or Metered) and IQ7 Series Microinverters to prevent
Electomagnetic Interference (EMI) noise above permissible limits from reaching home loads and the utility grid.
This document only provides details on how to install the EMI line lter with the IQ Gateway and IQ7 Series Microinverters. Refer to the IQ Gateway
(Standard or Metered) Quick Install Guide (QIG) for detailed installation instructions.
Preparation
A ) The following Enphase SKUs contain the EMI line lter:
Kit model
ENV-S-WB-230-LF-KIT This kit includes the IQ Gateway Standard and the EMI line lter (ELF-020-1P)
ENV-S- EM-230-LF-KIT This kit includes the IQ Gateway Metered and the EMI line lter (ELF-020-1P)
B ) For three-phase installations, ensure three EMI line lters are available on-site.

Installation
Installations in Europe that use IQ7 Series Microinverters
For installations in Europe using IQ7 Series Microinverters, Enphase requires the installation of an EMI line lter (ELF-020-1P) to prevent
Electromagnetic Interference (EMI) noise above permissible limits from reaching home loads and utility grid. The device is rated for 20 A,
50 Hz, and up to 250 VAC operation.
NOTE: This EMI line lter does not improve power line communication between the gateway and the microinverters; it suppresses the Electro-
magnetic Interference (EMI) noise.
A ) Ensure the EMI line lter is installed indoors or in an IP54 or higher rated enclosure.
B ) To minimize noise coupling, do not place incoming and outgoing cables for the EMI line lter next to each other.
C ) Refer to the wiring diagrams provided below to plan the installation of the EMI line lter.
NOTE:For three-phase systems, three EMI line lters are required to be installed on the site.
