Lightning and Surge Suppression
Enphase Microinverters have integral surge protection, greater than most traditional inverters. However, if
the surge has sufficient energy, the protection built into the microinverter can be exceeded, and the
equipment can be damaged. For this reason, Enphase recommends that you protect your system with a
lightning and/or surge suppression device. In addition to having some level of surge suppression, it is also
important to have insurance that protects against lightning and electrical surges. Enphase has tested the
following devices:
•
•
NOTE
: Protection against lightning and resulting voltage surge must be in accordance with
local standards.
Parts and Tools Required
In addition to the microinverters, PV modules, and racking, you will need the following:
Enphase Equipment
•
Enphase IQ Envoy
: Required to monitor production. IQ Envoy (model ENV-IQ-AM1-240)
communications gateway or IQ Combiner (model X-IQ-AM1-240-B, X-IQ-AM1-240-2, X-IQ-
AM1-240-3, X-IQ-AM1-240-3C).
•
Enphase Installer Toolkit
: Download the Enphase Installer Toolkit mobile app,
open it, and log in to your Enlighten account. Use it later to scan microinverter
serial numbers and connect to the IQ Envoy to track system installation progress.
