Micro-Inverter
Solar Grid Tie System
190W 240VAC or 208VAC

 

Enphase Energy presents the first commercially available Micro-Inverter system for residential and commercial solar PV applications.  The Enphase Micro-Inverter system utilizes advanced technologies to maximize energy harvest, increase system reliability and dramatically simplify design, installation and management.

Rather than using a large centralized inverter that converts the dc power from all PV modules to ac, the Enphase Micro-Inverter system uses an inverter for each PV module.  This has the following advantages:

     * Every module gets the benefit of individual Maximum Power Point Tracking (MPPT),
        thereby maximizing energy harvest.
     * Decreases system power reduction events due to single-module shading.
     * Incremental system growth capability - no need to purchase many expensive modules at one time.
     * Eliminates nearly all the dc system components such as junction boxes, batteries, fuses, cabling and
        their associated costs and installation time.
     * Improved reliability - single inverter failure does not disable entire system.

Communications Gateway

The module performance information generated by each Micro-inverter is collected by the Enphase communications gateway called the Energy Management Unit (EMU). The EMU then transmits this data over a broadband internet connection to the Enphase Enlighten™ website.

Enlighten™

The Enphase Enlighten website analyzes the per-module data collected by each Micro-inverter. Enlighten automatically detects any shortfall in energy production, identifies possible causes, and suggests solutions to correct the problem. The Enphase Enlighten website is constantly monitoring and managing every module on every installation.
