Enphase branch terminator for M215 installation, ET-TERM
The Engage Cable is a continuous 12 AWG (2.5 mm²) outdoor rated cable with integrated connectors for M215 and M250 microinverters. The connectors are preinstalled at intervals to accommodate PV module widths or lengths. The microinverters plug directly into the connectors, and the Engage Cable is terminated into a junction box that feeds electricity back to the system's AC disconnect. Engage Cables are specific to portrait or landscape module orientation as well as 208 VAC or 240 VAC output. The gap between connectors on a portrait cable of either voltage is 40" while the landscape cable has a 67" connector spacing to accommodate the width and length of a standard 60-cell module.
The cable can be cut to size. One end is wired directly into a junction box at the head of the branch circuit without a separate AC interconnect cable. The other end is sealed using an Engage Branch Terminator. The M215 or M250 microinverter AC cable connectors are then plugged into the regularly-spaced Engage Cable connectors. Any unused connectors must be protected with an Enphase waterproof Sealing Cap (the plastic covers on the connectors at shipment are not weather-tight and cannot be used in place of a Sealing Cap).
Engage Cables for both portrait and landscape installations are available in 40-connector lengths for 240 VAC single-phase, or in 30-connector lengths for 208 VAC three-phase systems, and include one Enphase Install Kit (4 Branch Terminators, 1 Cable Disconnect Tool, 5 Sealing Caps), and 100 wire clips. Cables in 8, 12, and 16-connector lengths with Enphase install kits (1 Branch Terminator, 1 Cable Disconnect Tool, 1 Sealing cap and tool, and 20, 30, or 40 wire clips) for portrait or landscape 240 VAC single-phase systems.
Both types of Engage Cables are also available, without an install kit, in bulk lengths with 240 connectors. This is useful for installers who plan to put in multiple M215 systems. The contents of the install kit can also be ordered individually.
A Branch Terminator is used to seal the stub ends of each branch circuit. The terminator separates and insulates the individual conductors contained in the Engage trunk cable. One terminator is needed per branch circuit. NOTE: The terminator is intended for one-time use only. The latching mechanism will be damaged if the terminator is removed after installation.
A watertight Sealing Cap is used to seal any unused trunk cable connectors to IP67 weatherproofing standards. Unused trunk cable connectors generally occur where the trunk cable transitions to another module row or needs to span a gap in the array.
The Engage Coupler is used to connect the cut ends of the Engage cable together or to join it to a lower cost standard cable without a junction box.
Stainless Steel Cable Clips are used to fasten Engage trunk cable to racking or to secure looped cabling and are available in packs of 100.
The Disconnect Tool is required to safely disconnect the microinverter’s AC output cable from the Engage connector. The tool is reusable, so one per job is usually sufficient
