My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.

Description Datasheet

Enphase 208VAC Landscape Engage Cabling

Unlike the M190 and M210, the M215's voltage (208 or 240 VAC) is determined by the Engage Cable selected. You will need 1 drop (connector) for each M215 in your array with an additional drop for each row after the first (ie. for 2 rows, add one drop).

Detailed Description:

The M215 incorporates DC connectors and an AC connector. There is no integral AC cable on the M215. The Enphase Cabling System accomplishes the AC connection.

The Cabling System 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 both portrait and landscape PV module orientations.

The cable is installed by simply rolling out the desired length of cable and cutting it to size. One end is wired directly into the junction box at the head of the branch circuit, eliminating the need for a separate AC interconnect cable. The other end is sealed from the environment using an Enphase Branch Terminator. The M215 AC cable connectors are then plugged into the regularly-spaced connectors.

The Enphase Cabling System is available in two connector spacing options and two voltage types. Depending upon installer needs, the cabling is also 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.

Voltage Types and Conductor Count

The voltage types are either 240VAC split phase or 208VAC three phase. All cable connectors bear labels indicating their cable voltage designation. Typically used for residential applications, 240VAC includes four conductors. This cabling should also be used for split phase 208VAC applications. Three-phase 208VAC cabling includes five conductors, and is used for most commercial installations. Because Enphase microinverters output onto two phases, three phase cabling balances the phases by rotating conductor use from one microinverter to the next.

Frequently Asked Questions
  • How many drops do I need?

    Each drop has a special M215 connector right in the middle, so you will need one drop for each M215 in your array. Be sure to add an extra drop for each row after the first to allow the cable reach up to the next row. Also note that you can have a maximum of 17 240VAC or 25 208VAC M215s on one string. If you need any help sizing your Enphase solar system, please give us a call at 888-899-3509 ext. 1.

  • How are the drops cut?

    Drops are cut at the halfway point between two connectors, allowing about 20" of cable between the last connector and the end of the cable for portrait layout and 33.5" for landscape layout.

  • Do I need 208 or 240 VAC?

    208 VAC is usually for commercial projects, while 240 VAC is for residential.

  • Which M215 do I need?

    The difference between the two M215s EcoDirect offers is in their connectors, so your choice depends on whether your panels have an MC4, Tyco, or SMK connector. We also offer an Ontario FIT M215 for those in Ontario, Canada.
