  • Product Description

    Power One, the world’s 2nd largest provider of solar inverters, has introduced the Power-One Microinverter. The Power One Microinverter System includes the Power One Microinverter, the CDD (Concentrator Data Device) for system monitoring and communication, and Aurora Vision, Power-One Aurora’s monitoring and analysis website. The Power One Microinverter System improves energy harvest, increases reliability, and dramatically simplifies design, installation and management of solar power systems.

    Don’t be restricted to modules that are 60 cells. With the wide DC voltage range, you are allowed virtually unlimited selection with 54, 60 and 72 cell solar panels being acceptable.

    The new Aurora 250 & 300-watt microinverter product offers something new to Power-One customers, the ability to individually link all modules within a specific installation is an alternative to the traditional Aurora string inverters Power-One is famous for.

    Benefits include module-level maximum power point tracking for increased energy yield per panel, improved safety on the roof with the elimination of high voltage DC strings, and individual solar panel monitoring and troubleshooting.


    ‘Electrolyte-free’ power converter to further increase the life expectancy and long term reliability

    Outdoor enclosure for unrestricted use under any environmental conditions

    Increased energy harvesting thanks to the MPPT algorithm which works at the level of each solar panel in any light condition

    Enhanced MPPT control with reduced DC input current ripple

    HF isolation to fits any application that requires the positive grounding of DC input terminals

    96.5% maximum efficiency

    Ease of installation by the implementation of a package inclusive of proprietary wireless communication hub

    Reduced susceptibility to fault. In case of a component failure only the energy produced from one PV module will be lost


    Maximum energy production
    Resilient to dust, debris, and shading
    Performance monitoring per module


    MTBF of 365 years
    System availability greater than 99.8%
    No single point of failure


    Quick & simple design, installation and management
    24/7 monitoring and analysis


    Low voltage DC
    Reduced fire risk
