Step 3: Plan, Cut, and Position the Engage Cable

The Engage Cable is a continuous length of 12 AWG (2.5 mm
connectors for microinverters. These connectors are preinstalled along the Engage Cable at intervals to
accommodate PV module widths. The microinverters plug directly into the connectors, and the Engage
Cable is terminated into the junction box that feeds electricity back to the system AC disconnect.
NOTE: Make sure you are using the correct 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 type.
a. Confirm that the cable matches the electrical utility service at the site per the following:

208 VAC (three-phase) Engage Cable at sites with three-phase 208 VAC service.

240 VAC Engage Cable at sites with 240 VAC single-phase service.
b. Plan the cable route so that the drop connectors on the Engage Cable align with each PV
module. Allow extra length for slack, cable turns and any obstructions.
c. Measure the path of the AC branch circuit and cut a length of Engage Cable to meet your
needs.
d. Lay the Engage Cable along the route it will travel, positioning the connectors so that they
align with the PV modules. Allow extra length for slack, cable turns and any obstructions.
WARNING: Plan the AC branches so that they do not exceed the maximum number of
microinverters in an AC branch circuit as listed on page 30 of this manual. You must
protect each microinverter AC branch circuit with a 20 A maximum breaker.
NOTE: Many PV modules have a central stiffening brace. In these cases, do not position the
connector and microinverter at the exact center of the PV module. Instead, position the drop
connectors so that the connectors do not conflict with the braces.
e. PV module widths vary by manufacturer. On the Engage Cable, connectors are spaced at
intervals to allow for the widest PV modules compatible with Enphase Microinverters. If
narrower PV modules are used, it may be necessary to account for excess cable by looping
the cable at suitable intervals.
