With microinverters, every solar module is operated with the efficiency and precision of digital electronics. This delivers greater energy harvest, higher reliability and richer intelligence.In addition, the safety and simplicity of parallel AC wiring makes systems easier to design, install and maintain.

A grid-tie inverter is an electrical device that allows solar power users to complement their grid power with solar power. It works by regulating the amount of voltage and current that is received from the direct current solar panels (or other D.C. energy source) and converting this into alternating current.

The main difference between an inverter and a grid-tie inverter is that the latter also ensures that the power supplied will be in phase with the grid power. This allows individuals with surplus power (wind, solar, etc) to sell the power back to the utility. This is sometimes called "spinning the meter backwards" as that is what literally happens.

The Enphase Energy Microinverter System improves energy harvest, increases reliabilty, increases reliability, and dramatically simplifies design, of installation and management of solar power systems.

The Enphase System includes the microinverter, the Eenvoy Communications Gateway, and the weeb-bases Enlighten monitoring and analysis website.

Enlighten

The Enlighten service provides an unprecedented level of intelligence to solar power system owners and installers.

Unlike conventional monitoring systems, which only monitor the inverter, Enlighten is continuously monitoring the health and performance of every solar module and microinverter in the array.

Enlighten's web-based analytics will identify and alert owners and installers to any deviation in performance, allowing for quick and hassle-free maintenance.

Features

Monitors each solar module
Multiple viewing modes and mobile device support
Automatically identifies and diagnoses issues
Remote troubleshooting and updates

Envoy

The Enphase Envoy Communications Gateway is the networking hub connecting every module and microinverter in your solar array to the internet.

The Envoy uses advanced powerline communications technology to connect to each microinverter without additional wiring or wireless configuration. System owners can easily check the status of their solar system using the Envoy’s LCD display, or get more detailed information through the Enlighten website.

For commercial installations, multiple Envoy devices are used in combination with Line Communications Filters (LCF) to separate networking domains across the site.

Envoy Features
