2.6 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:
• Leviton 51110-SRG
• Schneider SquareD HEPD50
NOTE: Protection against lightning and resulting voltage surge must be in accordance
with local standards.
2.7 Parts and tools required
In addition to the microinverters, PV modules, and racking, you will need the following:
Enphase Equipment
• IQ Gateway: Required to monitor production. IQ Gateway (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 App: Download the Enphase Installer App, open it, and log in to
your Enphase account. Use it later to scan the microinverter serial numbers and
connect to the IQ Gateway to track system installation progress. To download, go
to https://enphase.com/installers/apps or scan the QR code.
