Parts and Tools Required

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

Enphase Equipment

•
Engage Cable, as needed
NOTE: Order the correct Engage Cable type. Installers must order Engage Cable for either
240VAC single phase, typical for residential applications, or 208VAC three phase, typical for
commercial installations. All drop connectors on the Engage Cable bear labels indicating
the cable voltage designation. Use 240 VAC cable at sites with 208 single-phase service.
• 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

•
AC junction boxes
• 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 indicator lights on the undersides of the microinverters)

Lightning Surge Suppression

Lightning does not actually need to strike the equipment or building where the PV system is installed to
cause damage. Often, a strike nearby will induce voltage spikes in the electrical grid that can damage
equipment. Enphase Energy 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.
As the Enphase Limited Warranty does not cover "acts of God" such as lightning strikes, and since lightning
strikes can occur anywhere, it is best practice to install surge protection as part of any solar installation. We
recommend the following protection devices. These have been tested to ensure that they do not interfere with
power line communications. Install per vendor instructions.
Residential:
Vendor: Citel, Part Number DS72RS-120
Application: Residential 120/240V Split Phase where N-G bond exists.
Commercial:
Vendor: Citel, Part Number SP-120
Application: Branch panel protection
See the vendor datasheet for DS70R, (which includes the DS72RS-120) or for SP-120 at
