Enphase residential & commercial inverters

Enphase Engage Cable System for the M215

The Engage Cable is a continuous length of 12 AWG (2.5 mm²), outdoor rated cable with integrated connectors for M215 microinverters. The connectors are pre-installed along the Engage Cable 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.

The 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" (the approximate width of a typical 60-cell module). The landscape cable has a 67" connector spacing (approximate length of a standard 60-cell module).

The cable can be cut to size. One end is wired directly into the junction box at the head of the branch circuit, without a separate AC interconnect cable. The other end is sealed from the environment using an Engage Branch Terminator. The M215 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 dust covers on teh 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). We also supply cable 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-mode 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 installer 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 int eh Engage trucnk 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.

Stainless Steel Cable Clips are used to fasten Engage trunk cable to racking or to secure looped cabling. 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.

Enphase M210 Microinverter

The M210 Microinverter has a higher DC input voltage than the M215, and can be used with modules of up to 240W with peak power voltage of 31-50 VDC. The M210 is designed for higher-voltage 72 and 84-cell modules, like SANYO N-Series and A-Series modules, and many Sunpower modules. Each M210 Microinverter has a built-in AC connection pigtail for "daisy-chaining" the inverters together to form an AC circuit. Order one installation kit for each AC branch circuit of up to 13 modules in 240 VAC systems, or up to 18 modules for 208 VAC systems. The M210 Microinverters have a 15-year limited warranty.

Enphase M210 Microinverter Installation Accessories

Order one installation kit for each M215 AC branch circuit (up to 13 modules in a 240 VAC system, and 18 modules for a 208 VAC three-phase system). Each installation kit contains one 6' interconnect cable, one end plug, and a bracket to mount a small junction box to the array's racking. Interconnect cables are also available in 12' and 20' lengths. Terminate the interconnect cable in a junction box where it can be spliced to condctors running to the AC distribution panel (see Electrical Distribution for insulated terminal blocks). An extension cable (connectors on both ends) is required whenever inverters are mounted more than 6' apart.

Module Level Monitoring

Enphase Energy's per-module monitoring technology is integrated into the Enphase Microinverter System, meaning there's no need for a bolt-on or standalone third-party monitoring tool. Every microinverter communicates with the Enphase Enlighten website to show you a physically accurate representation of your entire system and the performance of each PV module in real time. Data is monitored 24/7 and Enlighten will immediately notify you via email of any issues it detects. For example, Enlighten will notify you if an individual module is under performing compared to its neighboring modules. One Envoy communications gateway is required for monitoring on each installation of up to 250 inverters. A Line Communication Filter is required for installations with more than 250 inverters.

The Enphase Envoy communications gateway plugs into any standard AC outlet and collects microinverter performance information over the existing power line. No additional wiring is required. By plugging the Ethernet cable of the Envoy into a broadband router, performance data is automatically transmitted to Enlighten using the site's existing internet connection, further simplifying installation. The Envoy comes with a 90-day free trial of Enlighten monitoring subscription. One-year and 5-year per-inverter subscriptions are available for continued monitoring. The Envoy is also the communications gateway for the Enphase Environ Smart Thermostat. CSA Listed to UL 60950.

Environ Smart Thermostat
Environ is a smart thermostat device that integrates with the Enphase Enlighten website, allowing owners to simultaneously manage their solar system along with their heating and cooling system in a single web-based platform. Environ makes it easy to take control of energy usage and lets owners set or adjust their home temperature at anytime and from anywhere, using a web browser or smart phone, as well as directly with the thermostat device.

Environ wirelessly connects to the Envoy Communions Gateway using the ZigBee communications protocol. The Envoy connects the Environ to the internet, allowing it to transmit and receive information from the Enlighten website.
