M250 Installation Planning

The Enphase Engage Cable

The M250 has integrated DC and AC cables and connectors. The DC connectors attach to the PV

module, while the AC connector attaches directly to the Engage Cable. No additional cabling is needed.

The Engage Cable is a continuous length of 12 AWG, outdoor rated cable, with integrated connectors for

microinverters. These connectors are preinstalled along the entire cable and spaced to accommodate

either portrait and landscape PV module orientations.

To install the cable, just roll out the desired length of

cable and cut it to size. One end is wired directly into

the junction box at the head of the branch circuit. The

other end is sealed from the environment using an

Engage Terminator. The M250 AC cable connectors

are then plugged into the regularly spaced connectors

as shown.

The Engage Cable is available in two connector

spacing options and two voltage types: 240 VAC and

208 VAC. To fit differing needs, the cabling is available

in a variety of lengths.

Connector Spacing Options

The gap between connectors on the cable can be either 1.025 meters (40”) or 1.7 meters (67”). The 1.025

meter spacing is best suited for connecting PV modules installed in portrait mode, while the 1.7 meter gap

is best suited to PV modules installed in landscape mode.
