  • Harvest Energy from Commercial Solar Modules up to 350W

    Each solar module in your commercial solar array will use one Enphase® C250 Microinverter to convert collected solar energy into usable AC power. Just plug one microinverter into every module. Designed for use with lower-power solar modules, the C250 Microinverter is ideal for 60-cell and 72-cell modules up to 350 Watts. And by reducing material labor and labor costs while increasing harvest, it delivers exceptional commercial project cost-efficiency.

    • Maximizes energy production and minimizes cost
    • 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

    When used with a transformer, the C250 Microinverter is suitable for medium and large commercial installations where power distribution is 277 V/480 WYE or medium voltage (MV).

    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® C250 Microinverter interfaces with the following additional Enphase® components:

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

    NOTE: Compatible with 60-cell and 72-cell modules ONLY. Solar modules and additional Enphase System components are not included. The transformer used must adapt the utility voltage (usually 480Y/277VAC) to no more than 248V line-to-neutral for connection to the Envoy-C and C250 microinverters.
