Title
  • It's the Enphase® M250 Microinverter

    If you’re looking for a system with a little more oomph, this fourth-generation microinverter from Enphase is a step up from the M215 inverter, making its 250W output suitable for both residential and limited commercial use.

    Like the residential M215 and the commercial C250, the M250 maximizes energy production and efficiency by transforming DC input into AC output via safer, isolated DC circuitry without a ground electrode conductor.

    Mom raised us to never be negative. But hey, electrons rock. The M250 is beautiful because it’s simple, and this means fewer parts and easier installation. How easy? A smart dog could probably do it, emphasis on smart. My Eddie chewed it to pieces.

  • Save Money & Installation Time

    Plug one Enphase® M250 Microinverter into each solar module in your PV system to convert the sun’s energy into usable AC power. Designed for use with high-power solar modules, the M250 Microinverter increases energy output and facilitates simple installation through its "all-AC" solution. The inverter is optimized for 60-cell modules up to 300 Watts, and supports low-voltage operation.

    You’re thinking this is the one? Tesla would approve.

    • Integrated ground eliminates need for GEC or WEEB
    • Reduces impact of dust, shading, and debris
    • No GEC, DC design, or string calculation needed
    • Easy to install with Enphase Engage Cable
    • Free remote monitoring via Enlighten online software

     

    About the Enphase System

    The Enphase Microinverter System comprises three main components: 1) the Microinverter, 2) Enlighten software, and 3) the Envoy Communications Gateway. Each Enphase Microinverter connects to the free, cloud-based Enlighten software (either My Enlighten for owners or Enlighten Manager for professionals). You can log into your online Enlighten account to monitor and manage your solar panel array from anywhere you have Internet access. Each microinverter transmits its performance data to your account via the Envoy Communications Gateway.

    The Enphase® M250 Microinverter interfaces with the following additional Enphase® components:

    • Engage® cable (12 AWG) with connectors
    • Enlighten® monitoring/analysis software
    • Envoy® Communications Gateway: Router connection between the inverter and Enlighten® software. Choose Envoy® for smaller systems or Envoy C® for up to 600 microinverters.

    NOTE: Compatible with 60-cell modules ONLY. Solar modules and additional Enphase System components are not included.
