Parts and Tools Required

In addition to the microinverters, PV modules, and racking, you will need the following.

Enphase Equipment


Enphase Envoy Communications Gateway (optional, but recommended)
BEST PRACTICE: Connect the Envoy before the solar installation is complete.
When powered up and connected for the first time, the Envoy may retrieve an automatic
upgrade from Enphase. Because this upgrade may take up to 20 minutes, connect the
Envoy first (connect to both AC power and to the broadband router) so that it performs
the upgrade well before the solar module installation is complete. For more information,
see the Envoy Communications Gateway Installation and Operation Manual.

Engage Cable, as needed. (See "Engage Cable Planning and Ordering Information" on page 29.)
NOTE: Order the correct Engage Cable type. Installers must order Engage Cable for
either 240 VAC single phase, typical for residential applications, or 208 VAC three phase,
typical for commercial installations. All drop connectors on the Engage Cable bear labels
indicating the cable voltage designation.

Cable clips

Sealing caps, as needed (for any unused drops on the Engage Cable)

Terminators, as needed (one needed at the end of each AC branch circuit)

Enphase disconnect tool (number 2 and 3 Phillips screwdrivers can be substituted)

Other Items


Outdoor-rated, weather-proof AC junction box(es)

Gland or strain relief fitting (one per AC junction box)

Continuous grounding conductor, grounding washers

Number 2 and 3 Phillips screwdrivers

Torque wrench, sockets, wrenches for mounting hardware

Adjustable wrench or open-ended wrench (for terminators)

Handheld mirror (to view LEDs on the undersides of the microinverters)

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
lightning and/or surge suppression devices. In addition to having some level of surge suppression, it is
important to have insurance that protects against lightning and electrical surges.
Install these devices per vendor instructions.
