M215 Installation and Operation

Step 3 – Position the Enphase Engage Cable

The Engage Cable is a continuous length of 2.5 mm

, 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. Use 5G2.5 Engage Cable at sites

with three-phase service, or use 3G2.5 Engage Cable at sites with single-phase service. Check

the labelling on the drop connectors to verify the voltage type.

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 7 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 centre 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.
