Enphase Energy Micro Inverter 190W 208VAC MC3

Enphase Energy
Micro-Inverter
M190-72-208 and M190-72-240

This inverter is not compatible with all solar modules - check the Module Compatibility List in the Product Documentation section above!

The Enphase Micro-inverter shifts DC to AC conversion from a large, centralized inverter to a compact unit attached directly to each solar module in the power system. Distributing the conversion process to each module makes the entire solar power system more productive, reliable, and smarter than traditional inverter systems.

The Enphase Micro-inverter system is the world’s most technologically advanced inverter system for use in utility-interactive applications. The three key elements of an Enphase Micro-inverter System are:

• the Enphase Micro-inverter
• the Enphase Envoy communications gateway
• the Enphase Enlighten™ web-based monitoring and analysis

This integrated system maximizes energy harvest, increases system reliability, and simplifies design, installation and management.

Frequently Asked Questions...

What is a micro-inverter? What is the Enphase Micro-inverter System?

An inverter is a power converter that converts direct current (DC) into alternating current (AC). Traditionally, this has meant one, centrally-located inverter converts all of the DC current from the entire PV array into grid-compliant AC power. A micro-inverter is a device that converts the DC output of a single solar module into grid-compliant AC power. AC power then travels upstream through an ordinary branch circuit to the service panel. The Enphase Micro-inverter System consists of the micro-inverters as well as the Envoy communications gateway and the Enlighten™ monitoring and analysis system.

 

What is an Envoy or Enphase Energy Energy Management Unit?

The Envoy (or EMU - Energy Management Unit) is the communications gateway device which relays performance statistics from the micro-inverters to the Enphase Enlighten website.

 

What is the difference between an Enphase deployment and a traditional solar deployment?

The Enphase system provides improvements in the following areas:
Productive

• Per-module MPPT maximizes energy production.
• Increases resilience to shade, dust and debris.
• High conversion efficiency.
• Increased system up-time.
• Greater production in low-light conditions.

Reliable

• No single point of failure.
• Design reduces component stress.
• Very low internal temperature rise.
• Designed to NEMA 6 rating.

Smart

• 24/7 monitoring on a per-module basis.
• Eliminates concern about where to place a large inverter.
• Dramatically reduces installation design.
• Modules can be mismatched and added as your requirements grow.
• Panels do not need to be collocated.

 

Can Enphase Micro-inverters work with other DC power sources such as wind installations?

Enphase Micro-inverters have only been designed and tested to work in solar PV installations.

 

Do all my modules need to match?

No. One of the advantages of a micro-inverter system is that it allows for mixing modules. Unlike traditional inverters that are based on a string installation, the Enphase branch circuit approach allows for varying power output levels. This also means that end-user customers have the flexibility of adding or changing modules over time. Please see the Module Compatibility List in the Product Documentation section above!

Compliance
The Enphase Micro-inverter is CSA Listed per UL1741 and can withstand surges of up to 6kV. Enphase Micro-inverter Systems undergo rigorous testing including HALT and HASS, ensuring reliability. Independent testing by Relex – a leading third party reliability expert – has shown an estimated Mean Time Between Failure (MTBF) of 119 years for Enphase Micro-inverters.
