Concentrated photovoltaics: a 4-junction solar cell

According to the brand's claims, it is currently the most efficient micro-inverter on the market. It holds a 35% market share in grid-tied inverters in the United States and over 98% in the micro-inverter market. Additionally, it represents the culmination of over 5 years of research and development. To help you assess this product, we have reviewed its features and the advantages it offers.

Technical Properties

One of its strengths is that it can operate under low light and voltage conditions. This allows it to optimize electricity production by 5 to 25% according to Enphase statistics. It is equipped with an integrated automatic disconnect system (VDE 0126-1-1) and a high-performance waterproof rating (IP67). It is compatible with various mounting systems, including integrated ones, and can be connected with most 60-cell photovoltaic modules. Its wiring network is 100% AC and has a good efficiency rate.

System and Installation

The Enphase micro-inverter is easy to install due to its innovative wiring system. As mentioned above, its wiring is 100% AC, which eliminates the need for DC circuits with junction boxes and fuses. Additionally, it can be installed directly under the modules or nearby, further simplifying the installation. The micro-inverter is paired with a very effective system. The Envoy communication gateway manages the monitoring of each module and each inverter. It uses powerline technology to network the micro-inverters without needing additional cables or wireless network configuration. Setup is automatic thanks to a Plug and Play system. Envoy monitoring data is sent to the Enlighten server via a standard internet router. Enlighten records and analyzes the data sent and enables remote system troubleshooting as well as updates.

To Summarize:

With this information, we leave it to you to judge the micro-inverter yourself. However, to summarize, we can highlight:

• A sophisticated system that improves installation monitoring and maintenance
• Simplified installation
• A secure system: by replacing DC cables with standard AC cables, the risks of fires and electrical accidents are reduced.
• A protected system: with this system, an inverter failure only affects a very small part of the system, unlike a traditional system. Moreover, over the long term, not all your panels will age at the same rate, and the premature aging of one panel will impact the entire production. The Enphase micro-inverter mitigates this disadvantage by leveling out these differences, offering the benefits of both an optimizer and a transformer for each panel.
• It comes with a 20-year warranty and a much longer lifespan compared to traditional inverters, as it operates at low voltage. Thus, with a standard inverter and a system expected to last around 25 years, you would have had to replace your inverter every 10 to 15 years; with this one, that's no longer necessary.
