    This manual contains important instructions for use during installation and maintenance of the Enphase M250™ Microinverter. ® 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 21: The Enphase Microinverter System

    M250 is isolated and insulated from ground. Because of this, the M250 does not require a GEC. As a result, the M250 takes less time to install than other microinverters, saves money, and increases safety. This manual details the safe installation and operation of the Enphase Microinverter. The three key elements of an Enphase Microinverter System include the: ...
  • Page 22: 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 23: Planning For Microinverter Installation

    For Engage Cable ordering information, see page 26. Compatibility and Capacity The Enphase M250 is compatible with 60-cell modules. The modules must use PV (photovoltaic) Wire. For more information, see “Technical Data” on page 29. Refer to the http://www.enphase.com/support...
  • Page 24: Parts And Tools Required

    For this reason, Enphase recommends that you protect your system with lightning and/or surge suppression devices. In addition to having some level of surge suppression, it is also important to have insurance that protects against lightning and electrical surges.

    M250 Installation and Operation Enphase Microinverter Installation Installing the Enphase Microinverter System involves several key steps. Each step listed here is detailed in the following pages. Follow the instructions in this section to install Enphase M250 Microinverters. Step 1: Connect the Envoy...
  • Page 26: Step 1: 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 28: Step 3: 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 31: Step 6: 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 24. Sealing caps may not be reused.
  • Page 32: Step 7: Terminate The Unused End Of The Engage Cable

    Screw the hex nut onto the cap. Never unscrew the hex nut as this can twist and damage the cable. g. Hold the cap 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 33: Step 8: Connect The Engage Cable To Ac Junction Box(Es)

    NOTE: The green wire acts as equipment ground (EGC). Because the DC circuit is isolated and insulated from ground, the M250 does not require a GEC.

    2. Turn ON the main utility-grid AC circuit breaker. Your system will start producing power after a five-minute wait time. 3. The Enphase Microinverters will begin communicating over the power lines to the Envoy. time required for the Envoy to discover all of the microinverters varies with the number of microinverters in the system and quality of the power line communications.
