Engage Cable Planning and Ordering
The Engage Cable is a continuous length of outdoor-rated cable with integrated connectors for
microinverters. These connectors are preinstalled along the Engage Cable at intervals to accommodate
varying PV module widths. The microinverters plug directly into the cable connectors.
The cabling is compatible with a variety of PV racking systems. For a list of approved PV racking
systems, refer to the PV Racking Compatibility document on the Enphase website
(http://www.enphase.com/support).
Selecting Cable Type
Enphase Engage Cable is available in two different voltage types and multiple connector spacing
options. Depending upon installer needs, the cable is also available in different lengths.
Connector Spacing Options
Engage Cable for is available in three connector spacing options. The gap between connectors on the
cable can be 1.025 metres (40”), 1.7 metres (67”), or 2.1 metres (84”). The 1.025 metre spacing is best
suited for connecting PV modules installed in portrait orientation, while the 1.7 metre and 2.0 metre
spacing allows you to install 60-cell and 72-cell PV modules in landscape orientation.
