Manufacturer Enphase
The Enphase Micro-Inverter system is the world's most technologically advanced inverter system for use in utility interactive applications.

Each Enphase Micro-Inverter is individually connected to each PV module in your array. This unique configuration means that an individual Maximum Peak Power Point Tracker (MPPT) controls each PV module. This insures that the maximum power available from each PV module is exported to the utility grid regardless of the performance of the rest of the PV modules in the array which may be affected by shading, soiling, orientation, module mismatch, etc.

The three key elements of an Enphase Micro-Inverter System are: 1) the Enphase Micro-Inverter, 2) Envoy Communications Gateway, and 3) the Enlighten web based analytics and visualization. All three elements are highly integrated to provide a comprehensive energy production and management system.

Solar systems using Enphase Micro-Inverters are extremely simple to design and install. There are no string calculations needed. Individual PV modules may be installed in any combination of module quantity, type, age and orientation. There are no cumbersome centralized or string inverters to install. Each Micro-Inverter quickly mounts on the PV racking, directly beneath each PV module. Low voltage DC wires connect from the PV module directly to the co-located Micro-Inverter, eliminating the risk of personnel exposure to 600Vdc power. The Energy Management Unit (Emu) communications gateway is installed by simply plugging it into any convenient 120Vac wall socket. The full network of Enphase Micro-Inverters will automatically begin reporting to the Enphase Enlighten web server. The Enlighten analytics software lets you know not only the immediate and historical system performance trends, but also informs you when the PV system is not performing as expected. Note: This inverter uses locking MC connections (MC-4)
