Step 3 - Position The Enphase Engage Cable - enphase M215 Installation And Operation Manual

Step 3 – Position the Enphase Engage Cable
The Engage Cable is a continuous length of 12 AWG (2.5 mm2), outdoor rated cable with integrated
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 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 type. Installers can use 240 VAC cable at sites with 208 single-phase
service.
a. Lay the Engage Cable along the route it will travel, positioning the connectors so that they align
with the PV modules.
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 27 of this manual. You must protect
each microinverter AC branch circuit with a 20A 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.
b. 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.
