Page 4: Important Safety Information
Do NOT disconnect the PV module from the Enphase Microinverter without first removing AC • power. Be aware that the M215 has field adjustable voltage and frequency trip points that you must set • before the system can produce power. Only an authorised installer with the permission and following requirements of the local electrical authorities should make adjustments. -
Page 5: The Enphase Microinverter System
M215 Installation and Operation The Enphase Microinverter System The Enphase Microinverter System is the world’s most technologically advanced inverter system for use in grid- connected applications. This manual details the safe installation and operation of the Enphase Microinverter. The three key elements of an Enphase Microinverter System include the: Enphase M215 Microinverter •... -
Page 6: How The Microinverter Works
M215 Installation and Operation How the Microinverter Works The Enphase Microinverter maximises energy production from your photovoltaic (PV) array. Each Enphase Microinverter is individually connected to one PV module in your array. This configuration means that an individual Maximum Peak Power Point Tracker (MPPT) controls each PV module. This ensures that the maximum power available from each PV module is exported to the electricity network regardless of the performance of the other PV modules in the array. -

Compatibility and Capacity The Enphase M215 Microinverters are electrically compatible with most 60-cell PV modules. For more information, see Technical Data on page 24 of this manual. -
Page 8: Parts And Tools Required
M215 Installation and Operation Parts and Tools Required In addition to the microinverters, PV modules, mounting rail, and associated hardware, you will need the following. Enphase Equipment Enphase Envoy™ Communications Gateway • Engage Cable, as needed • NOTE: Order the correct Engage Cable type. Use 5G2.5 Engage Cable at sites with three- phase service, or use 3G2.5 Engage Cable at sites with single-phase service. -
Page 9: Installation Procedure
M215 Installation and Operation Installation Procedure Installing the Enphase Microinverter System involves several key steps. Each step listed below is detailed in the following pages. Step 1 – Measure AC Voltage at the Electricity network connection Step 2 – Install the AC Branch Circuit Junction Box Step 3 –... -
Page 10: Step 2 - Install The Ac Branch Circuit Junction Box
AC branch circuits that contain the maximum allowable microinverters. This is due to high inherent voltage rise on the AC branch circuit. For more information, refer to our Technical Brief, Voltage Drop Considerations for M215, at http://www.enphase.com/support/downloads. -
Page 11: Step 3 - Position The Enphase Engage Cable
M215 Installation and Operation Step 3 – Position the Enphase Engage Cable The Engage Cable is a continuous length of 2.5 mm , outdoor rated cable with integrated connectors for microinverters. These connectors are preinstalled along the Engage Cable at intervals to accommodate PV module widths. -
Page 12: Step 4 - Attach The Microinverters To The Mounting Rail
If installing the M215 at an angle, check that this angle does not allow for collection of water in the recesses of the microinverter. -
Page 13: Step 5 - Dress The Engage Cable
M215 Installation and Operation Step 5 – Dress the Engage Cable a. Attach the Engage Cable to the mounting rail using clips or tie wraps. NOTE: There are two release-holes in the drop connector on the cable. These are not for mounting but are used to disconnect the connector. -
Page 14: Step 6 - Connect The Microinverters
M215 Installation and Operation Step 6 – Connect the Microinverters a. Remove and discard the temporary shipping cap from the Engage Cable and connect the microinverter. There are two latching mechanisms within the connectors. Listen for two clicks as the connectors engage. Ensure that both latching mechanisms have engaged. -

M215 Installation and Operation Step 7 – Terminate the Unused End of the Engage Cable Terminate the far end of the Engage Cable as follows. a. Remove 60mm (2.5 inches) of the cable sheath from the conductors. b. Slide the hex nut onto the Engage... -
Page 16: Step 8 - Connect The Engage Cable To Ac Junction Box(Es)
M215 Installation and Operation Step 8 – Connect the Engage Cable to AC Junction Box(es) a. Connect Engage Cable into the AC branch circuit junction box using an appropriate gland or strain relief fitting. The Engage Cable requires a strain relief connector with an opening of 1.3 cm (0.5 inches) in diameter. -
Page 17: Step 9 - Complete The Installation Map
Mate the microinverters and PV modules as required. Repeat for all remaining PV modules using one microinverter for each PV module. WARNING: The M215 can be paired only with a 60- cell PV module. Copyright © 2012 Enphase Energy... -
Page 18: Step 11 - Build The Virtual Array
M215 Installation and Operation Step 11 – Build the Virtual Array When the system is energised and the Envoy detects all the installed microinverters, you can create the virtual array in Enlighten from the installation map you created. Once the virtual array is built, Enlighten displays a graphic representation of the PV system. -
