Enphase
The Enphase Energy Microinverter System improves energy capture, increases reliability, and dramatically simplifies design, installation and management of solar power systems. The Enphase System includes the Microinverter, the Envoy Communications Gateway, and the web-based Enlighten monitoring and analysis service.
Each Microinverter is a fully-integrated device that converts the DC output from a single PV module into grid-compliant AC power. The microinverter system is designed to maximize energy harvest, increase system reliability and dramatically simplify design, installation and system management while also improving safety.
The power from each PV module is individually tracked by a Microinverter, eliminating losses caused by underperforming modules in the array. Microinverters help realize the full energy potential of every PV array, reducing the power-limiting effects of shading, dust, debris, module mismatch, and thermal differences. Problems are isolated to a small fraction of the PV array, while the rest of the PV system continues to function optimally. Service is simplified to routine maintenance.
Microinverters eliminate the need for string sizing exercises that require fitting equal lengths of module strings on a roof. Each PV module is connected directly to its own microinverter and mounted on the racking underneath. The microinverter's AC wire harnesses are connected to form a continuous AC branch circuit that leads ultimately to the AC utility distribution center.
System safety is enhanced since all of the output wiring from the PV array is AC, and therefore doesn't contain hazardous DC voltages once the AC power is shut down for service or emergency. If the AC to the array is shut off, only the DC voltage of a single module (typically under 50VDC) is present in the array creating a much safer situation for maintenance personnel or firefighters.
Model Selection
Enphase makes microinverters for most popular PV modules:
The M190 inverters can be used with modules of up to 230 watts made with 60 to 72 cells in series. Available with either 240VAC single-phase output, or 208VAC output for three-phase systems. Max branch circuit size is 15A (up to 15 inverters in 240VAC single-phase systems and up to 21 inverters in 208VAC three-phase systems).
The M210 is a higher input voltage version of the M190, and can be used with modules of up to 240 watt with peak power voltage of 31-50 volts. This version is designed for high-efficiency modules like SunPower and SANYO.
The New D380 TwinPack Microinverter is comprised of two Enphase microinverters in a single enclosure. Its innovative cabling system further reduces balance-of-system and installation costs because it's possible to install 33% more modules per circuit with the D380. The D380 has a black anodized housing, which improves aesthetics and allows for better thermal dissipation. The D380 TwinPack is optimized for commercial applications, but is applicable to many residential installations as well. D380 Microinverter TwinPacks are auto-sensing and compatible with 240Vac split-phase and 208Vac WYE three-phase utility systems. Maximum branch circuit size is 20A.
The Enphase Microinverter is qualified to a NEMA 6 environment rating and operates at full power at temperatures from -40°C (-40°F) to 65°C (149°F), allowing applications in harsh environments.
CSA Listed to UL 1741 for the U.S. and Canada. 15-year standard warranty.

Module Level Monitoring
Enphase Energy's per-module monitoring technology is integrated into the Enphase Microinverter System, meaning there's no need for a bolt-on or standalone third-party monitoring tool. Every microinverter communicates with the Enphase Enlighten website to show you a physically accurate representation of your entire system and the performance of each PV module in real time. Data is monitored 24/7 and Enlighten will immediately notify you via email of any issues it detects. For example, Enlighten will notify you if an individual module is under performing compared to its neighboring modules. One Envoy communications gateway is required for monitoring on each installation of up to 250 inverters. A Line Communication Filter is required for installations with more than 250 inverters.
The Enphase Envoy communications gateway plugs into any standard AC outlet and collects microinverter performance information over the existing power line. No additional wiring is required. By plugging the Ethernet cable of the Envoy into a broadband router, performance data is automatically transmitted to Enlighten using the site's existing internet connection, further simplifying installation. The Envoy comes with a 90-day free trial of Enlighten monitoring subscription. One-year and 5-year per-inverter subscriptions are available for continued monitoring. The Envoy is also the communications gateway for the Enphase Environ Smart Thermostat. CSA Listed to UL 60950.

D-series Inverter Installation Accessories
Each 20A AC branch circuit may have up to 20 modules in a 240-volt system and 30 modules in a 208-volt ystem. The D-series cables are ordered separately from the inverter. An extension cable is required when inverters are mounted more than 6 feet apart from each other. The "3-drop" trunk cables allow connection for three D380 inverters (for six PV modules). End caps seal off unused drops and the end of the branch circuit.
