Page 5: Important Safety Information
Refer to product instructions. Safety and Advisory Symbols To reduce the risk of electrical shock, and to ensure the safe installation and operation of the Enphase® Microinverter, the following safety symbols appear throughout this document to indicate dangerous conditions and important safety instructions. - Page 6 You must protect each microinverter AC branch circuit with a 20A maximum breaker. WARNING: Do not connect Enphase Microinverters to the grid or energize the AC circuit(s) until you have completed all of the installation procedures and have received prior approval from the electrical utility company.
- Page 7 PV module. Instead, position the drop connectors so that the connectors do not conflict with the braces. NOTE: If you need to remove a sealing cap, you must use the Enphase disconnect tool or a #3 Phillips screwdriver. Sealing caps may not be reused.

Page 8: The Enphase Microinverter System
System™ is the world’s most technologically advanced inverter system for The Enphase Microinverter use in utility-interactive applications. This manual details the safe installation and operation of the Enphase Microinverter. With the M215-60-2LL-S22-IG, S23-IG, or S24-IG, the DC circuit within the M215 is isolated and insulated from ground. -
Page 9: How The Microinverter Works
Microinverter systems are inherently more reliable than traditional inverters. The distributed nature of a microinverter system ensures that there is no single point of system failure in the PV system. Enphase Microinverters are designed to operate at full power at ambient temperatures as high as 65 C (150 F). -
Page 10: Planning For Microinverter Installation
For more information, see “Technical Data” on page 35 of this manual. Refer also to the Enphase Compatibility Calculator at: http://enphase.com/module-compatibility-calculator-m250-update/ to ensure PV module electrical compatibility. -
Page 11: Grounding Considerations
For this reason, Enphase recommends that you protect your system with lightning and/or surge suppression devices (see table). In addition to having some level of surge suppression, it is also important to have insurance that protects against lightning and electrical surges. -
Page 12: Parts And Tools Required
When powered up and connected for the first time, the Envoy may retrieve an automatic upgrade from Enphase. Because this upgrade may take up to 20 minutes, connect the Envoy first (connect to both AC power and to the broadband router) so that the upgrade completes well before the solar module installation is complete. -

For more information on Grid Profiles or if you need to change the grid profile subsequent to this initial procedure, see the Envoy Communications Gateway Installation and Operation Manual at: http://www.enphase.com/support. 2014 Enphase Energy Inc. All rights reserved. 141-00012 Rev 06... -
Page 15: Step 2: Connect The Envoy
BEST PRACTICE: When powered up and connected for the first time, the Envoy may retrieve an automatic upgrade from Enphase. Because this upgrade may take up to 20 minutes, connect the Envoy first at the site (connect to both AC power and the broadband router) so that it performs the upgrade well before the solar module installation is complete. -

Page 17: Step 4: Plan, Cut, And Position The Engage Cable
PV module widths vary by manufacturer. On the Engage Cable, connectors are spaced at intervals to allow for the widest PV modules compatible with Enphase Microinverters. If narrower PV modules are used, it may be necessary to account for excess cable by looping the cable at suitable intervals. -
Page 18: Step 5: Attach The Microinverters To The Pv Racking
8 mm (5/16”) mounting hardware: 9 N m (80 to 85 in-lbs) NOTE: Using a power screwdriver to tighten the mounting hardware is not recommended due to the risk of thread galling. 2014 Enphase Energy Inc. All rights reserved. 141-00012 Rev 06... -
Page 19: Step 6: Ground The Microinverters (If Required)
NOTE: Ground the system in accordance with all applicable local electrical codes and the National Electrical Code (NEC), ANSI/NFPA 70. NOTE: CSA has evaluated and approved the Wiley Electronics “WEEB” grounding washers for use with the Enphase Microinverter. Compatible grounding washer part numbers and installation guidelines are included in the Racking Compatibility List. -
Page 20: Step 7: Dress The Engage Cable
NOTE: When looping the Engage Cable, do not form loops smaller than 4.75 inches (12 cm) in diameter. WARNING: Tripping Hazard. Loose cables can become a tripping hazard. Dress the Engage Cable to minimize this potential. 2014 Enphase Energy Inc. All rights reserved. 141-00012 Rev 06... -
Page 21: Step 8: Connect The Microinverters
Unused AC connectors are live when the system is energized by the utility system. Sealing caps may not be reused. NOTE: If you need to remove a sealing cap, you must use the Enphase disconnect tool or a #3 Phillips screwdriver. See “Disconnect a Microinverter” on page 30. Sealing caps may not be reused. -
Page 22: Step 9: Terminate The Unused End Of The Engage Cable
Place cap over the wire organizer. g. Hold the cap stationary with an Enphase disconnect tool, or insert a #2 Phillips screwdriver. h. Use a 22 mm (7/8 inch) wrench to tighten the hex nut until the latching mechanism is screwed all the way to the base. -
Page 23: Step 10: Connect The Engage Cable To Ac Junction Box(Es)
S22-IG, S23-IG, and S24-IG do not require a GEC. Ground fault protection (GFP) is integrated into the microinverter. Balanced 208 VAC (three-phase) is accomplished by alternating phases between microinverters as shown: 2014 Enphase Energy Inc. All rights reserved. 141-00012 Rev 06... -
Page 24: Step 11: Complete The Installation Map

Adhere to all the safety measures described throughout this manual. Qualified personnel can use the following troubleshooting steps if the PV system does not operate correctly. WARNING: Do not attempt to repair the Enphase Microinverter; it contains no user- serviceable parts. If the microinverter fails, contact Enphase customer service to obtain an RMA (return merchandise authorization) number and start the replacement process. -
Page 28: Gfdi Fault
You can attempt to clear this fault through Enlighten or by using the Envoy interface. If the condition does not clear after you perform the following procedure, contact Enphase Energy customer support at support@enphaseenergy.com. - Page 29 PV module isn’t functioning correctly. If it stays in place, the problem is with the microinverter. Call Enphase Customer Support for help in reading the microinverter data and for help in obtaining a replacement microinverter, if needed.

Page 30: Disconnect A Microinverter
NOTE: Take care when measuring DC current as most clamp-on meters must be zeroed first and tend to drift with time. 5. Disconnect the PV module DC wire connectors from the microinverter using the Enphase disconnect tool. 6. If present, loosen the ground cleat screw and remove the grounding electrode conductor. -
Page 31: Install A Replacement Microinverter
This starts a 30-minute scan at the Envoy to discover the new microinverter. 11. Use Enlighten’s Array Builder to add the newly detected microinverter to the virtual array. 12. Ship the old microinverter to Enphase using the supplied return-shipping label. 2014 Enphase Energy Inc. All rights reserved. -
Page 32: Engage Cable Planning And Ordering
PV Racking Compatibility document on the Enphase website (http://www.enphase.com/support). Selecting Cable Type Enphase Engage Cable is available in two different voltage types and two connector spacing options. Depending upon installer needs, the cable is also available in different lengths. Connector Spacing Options The gap between connectors on the cable can be either 1.025 meters (40”) or 1.7 meters (67”). -
Page 33: Voltage Type And Conductor Count Options
Account for the number of Enphase Microinverters to be installed on the AC branch circuit. Make sure to allocate the correct number of connectors, including extra connectors for gaps and turns. - Page 34 4. Create wiring extensions for Engage Cable NOTE: The Engage Coupler only supports #12 TC-ER, which may not be sufficient for homerun wiring. Enphase Energy recommends maintaining less than 2% voltage drop across all wiring. In situations where you cannot use an Engage Coupler, you can use an electrical junction box to transition between cable types.
