  • Page 5: Important Safety Information

    This manual contains important instructions for use during installation and maintenance of the Enphase M215-Z™ 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 6: The Enphase Microinverter System

    Zep-Compatible M215-Z Installation and Operation The Enphase Microinverter System Enphase and Zep have partnered to introduce the M215-Z Microinverter. The M215-Z features a redesigned mounting bracket that attaches to Zep Compatible™ solar modules to enable seamless integration of the Enphase Microinverter System with the Zep System.

  • Page 7: The M215-Z

    Each M215-Z is individually attached to one PV module in your array. This one-to-one 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 utility grid regardless of the performance of the other PV modules in the array.

    Doing so may cause death or injury to persons, or damage to equipment. Compatibility and Capacity The Enphase M215-Z Microinverters are electrically compatible with most 60-cell PV modules. For more information, see Technical Data on page 26 of this manual.

  • Page 9: Lightning Surge Suppression

    As the Enphase Limited Warranty does not cover “acts of God” such as lightning strikes, and since lightning strikes can occur anywhere, it is best practice to install surge protection as part of any solar installation. We recommend the following protection devices.
